An anchoring system is a combination of a nanofiber scaffold material and an arthroscopically deployable suture anchor. The anchor is deployed into a bone tunnel using common techniques. The nanofiber material extends out of the proximal end of the implant, once deployed. The implant also includes pre-loaded sutures or has the ability to accept and lock sutures to the implant. For an implant pre-loaded with suture, the implant is placed into the bone, the material is deployed above the anchor onto the surface of the bone, suture is passed through the soft tissue, and knots are tied to secure the tissue against the bone, sandwiching the material between the bone and tissue, to provide a pathway for cells from the bone marrow to the soft tissue-bone interface, promote the healing response, provide a biomimetic structure that cells readily adhere to, and create a larger healing footprint.

A method for securing suture to bone comprises drilling a hole in a desired portion of bone at a desired procedural site, passing a strand of suture through a portion of soft tissue to be approximated to the portion of bone, and extending the free suture ends proximally from the soft tissue. The suture is loaded into an anchor implant. Using an inserter, on a distal end of which is attached the anchor implant, the anchor implant is manipulated into the bone hole. The suture is then tensioned to a desired level by pulling on the free suture ends, after the anchor implant is positioned in the bone hole. The free suture ends are wrapped about a suture cleat on an inserter handle once the desired tension level is achieved. A proximal anchor component is moved distally to engage with a distal anchor component to lock the anchor in place within the bone hole, and to lock the suture in place within the anchor. Then, the inserter is removed from the procedural site.

A wicking component is integrated into an arthroscopically deployable bone anchor, and is intended to improve soft tissue-to-bone repair. Once deployed, the fibrous wick component extends from within the bone tunnel, out of the hole, and to the bone-tendon interface on the bone surface. The tissue is approximated against the bone, sandwiching the wick material between the bone and tissue. The wick component is ideally a polymeric fibrous or tissue-based scaffold that provides a pathway for cells (autologous bone marrow constituents and blood) to travel from within the bone to the soft tissue-bone interface, accelerating and promoting the healing response. The system provides a biomimetic structure that stimulates the extracellular matrix to encourage cell attachment and potentially improve the healing response. The wick component does not need to be integrated into a suture anchor and installed when the suture anchor is deployed. For example, the wick component could be placed above or near a traditional suture anchor after it has been deployed.

An anchoring system for securing tissue to bone includes an implant having a body through which a suture eyelet extends transversely, a suture recess extending along a portion of a length of the body, having a predetermined depth below an outer surface of the body, and a suture pinch ramp disposed at a proximal end of the suture recess. The suture pinch ramp has a depth approximately equal to the predetermined depth at a distal end thereof and sloping outwardly in a proximal direction so that a depth of a proximal end of the suture pinch ramp approaches zero. An insertion member includes an insertion tube and a handle which is engageable with the anchor body to deploy the anchor in a selected bone site.

A soft tissue fixation system, most typically applicable to orthopedic joint repairs, such as anterior cruciate ligament (ACL) knee repair procedures, comprises an implant which is placeable in a tunnel disposed in a portion of hone, wherein the tunnel is defined by walls comprised of bone. A first member is deployable outwardly to engage the tunnel walls for anchoring the implant in place in the tunnel, and a second member is deployable outwardly to engage tissue material to be fixed within the tunnel. The second member also functions to move the tissue material outwardly into contact with the tunnel walls to promote tendon-bone fixation. Extra graft length is eliminated by compression of the tendon against the bone at the aperture of the femoral tunnel, which more closely replicates the native ACL and increases graft stiffness. The inventive device provides high fixation of tendon to bone and active tendon-bone compression. Graft strength has been found to be greater than 1,000 N (Newtons), which is desirable for ACL reconstruction systems.
A simple, threaded suture anchor is pre-loaded with suture in a configuration that allows a surgeon to compress tissue against the bone without tying a knot. The knot-tying step is replaced by a simple suture looping step which requires less time and is not prone to errors in knot tying technique. The suture anchor is a screw-in style anchor body. The suture is loaded into the anchor in a configuration that allows it to create a loop on top of the tissue after it has been passed through the tissue from bottom to top. The suture limbs are then loaded into a knotless anchor which is implanted off the lateral edge of the tissue. Tensioning of the suture limbs in the knotless anchor tightens the loop on top of the tissue, providing a fulcrum point of fixation over the pre-loaded suture anchor without the otherwise need for requisite knot tying.

An all-suture suture anchor system includes an all-suture anchor, an inserter, and a specially designed drill. The drill is used to enlarge the hole and create a pocket under the bone surface from the pre-drilled hole. The created pocket is intended to accommodate the expansion of the anchor when deployed into the bone, generating a true mechanical interference under the bone surface. The anchor is loaded on the inserter and placed at full length vertically inside the drilled hole. While holding the inserter on top of the drilled hole, so that a feature on the inserter keeps the anchor to a desired depth below the bone surface, tension is applied to the suture limb that is connected to the bottom end of the anchor. This tensioning step causes the length of the anchor to contract vertically and the anchor is simultaneously expanded circumferentially to fill the pocket previously created by the drill. Since the pocket created by the drill is intended to contain the deployed anchor, the deployed position of the anchor is consistently predictable.

Inserter for soft tissue or bone-to-bone fixation device and methods
A positioning and installation tool for a fixation implant is inserted through a single, simple drill hole and positioned in place. The device controls the degree to which the implant is deployed and prevents accidental disengagement of the device from the implant before deployment has completed. The device also guides the components of the implant involved in active tendon compression at the aperture of the bone tunnel. The implant is deployed simply by rotating a knob, thereby creating an anchor point of high stiffness and fixation strength. When deployment has completed, the inserter is disengaged from the affixed implant by simply pulling a release mechanism.
An anchoring system is a combination of a nanofiber scaffold material and an arthroscopically deployable suture anchor. The anchor is deployed into a bone tunnel using common techniques.

A method for securing suture to bone comprises drilling a hole in a desired portion of bone at a desired procedural site, passing a strand of suture through a portion of soft tissue to be approximated to the portion of bone, and extending the free suture ends proximally from the soft tissue. The suture is loaded into an anchor implant. Using an inserter, on a distal end of which is attached the anchor implant, the anchor implant is manipulated into the bone hole. The suture is then tensioned to a desired level by pulling on the free suture ends, after the anchor implant is positioned in the bone hole. The free suture ends are wrapped about a suture cleat on an inserter handle once the desired tension level is achieved. A proximal anchor component is moved distally to engage with a distal anchor component to lock the anchor in place within the bone hole, and to lock the suture in place within the anchor. Then, the inserter is removed from the procedural site.

A method of anchoring soft tissue to a suitable bone site, using a soft suture anchor, includes steps of disposing the soft suture anchor on a shaft of an inserter, and securing a proximal end of a tensioning suture limb, extending proximally from the soft suture anchor, to structure in a handle of the inserter, so that it is maintained in place at a first level of holding tension (Thold). The inserter shaft is inserted into a bone hole at a desired procedural site, so that the soft suture anchor is positioned at a location where it is to be anchored.

A soft tissue fixation system, most typically applicable to orthopedic joint repairs, such as anterior cruciate ligament (ACL) knee repair procedures, comprises an implant which is placeable in a tunnel disposed in a portion of bone, wherein the tunnel is defined by walls comprised of bone. A first member is deployable outwardly to engage the tunnel walls for anchoring the implant in place in the tunnel, and a second member is deployable outwardly to engage tissue material to be fixed within the tunnel. The second member also functions to move the tissue material outwardly into contact with the tunnel walls to promote tendon-bone fixation. Extra graft length is eliminated by compression of the tendon against the bone at the aperture of the femoral tunnel, which more closely replicates the native ACL and increases graft stiffness. The inventive device provides high fixation of tendon to bone and active tendon-bone compression. Graft strength has been found to be greater than 1,000 N (Newtons), which is desirable for ACL reconstruction systems.
A positioning and installation tool for a fixation implant is inserted through a single, simple drill hole and positioned in place. The device controls the degree to which the implant is deployed and prevents accidental disengagement of the device from the implant before deployment has completed. The device also guides the components of the implant involved in active tendon compression at the aperture of the bone tunnel. The implant is deployed simply by rotating a knob, thereby creating an anchor point of high stiffness and fixation strength. When deployment has completed, the inserter is disengaged from the affixed implant by simply pulling a release mechanism.

An anterior cruciate ligament (ACL) surgical repair technique involves the use of a single femoral and tibial tunnel and an implant that separates and positions two distinct bundles. This allows for the surgeon to create a more anatomic reconstruction with a procedure that is less technically demanding, can be performed using a transtibial or anteromedial approach, minimizes tunnel widening, and decreases operative time. The result is a strong fixation option for soft tissue grafts, with circumferential graft compression at the aperture, high pull-out strength, and ease of use. The graft bundles are positioned in a more anatomic orientation through the above noted single femoral and tibial tunnel.

Devices, systems, and methods for material fixation
A material fixation system is particularly adapted to improve the tendon-to-bone fixation of hamstring autografts, as well as other soft tissue ACL reconstruction techniques. The system is easy to use, requires no additional accessories, uses only a single drill hole, and can be implanted by one person. Additionally, it replicates the native ACL by compressing the tendons against the aperture of the tibial tunnel, which leads to a shorter graft and increased graft stiffness. It is adapted to accommodate single or double tendon bundle autografts or allografts. It also provides pull out strength measured to be greater than 1000 N.
A soft tissue fixation system, most typically applicable to orthopedic joint repairs, such as anterior cruciate ligament (ACL) knee repair procedures, comprises an implant which is placeable in a tunnel disposed in a portion of bone, wherein the tunnel is defined by walls comprised of bone.

The second member also functions to move the tissue material outwardly into contact with the tunnel walls to promote tendon-bone fixation. Extra graft length is eliminated by compression of the tendon against the bone at the aperture of the femoral tunnel, which more closely replicates the native ACL and increases graft stiffness. The inventive device provides high fixation of tendon to bone and active tendon-bone compression. Graft strength has been found to be greater than 1,000 N (Newtons), which is desirable for ACL reconstruction systems.

Devices, systems and methods for material fixation
Devices, systems and methods for fixation of tendon to bone are described. An exemplary surgical implant is a modified bone anchor that is able to grasp the tendon and hold it firmly in a bone tunnel. Once deployed, the anchor delivers lateral compression to the tendon, providing direct tendon to bone compression to facilitate healing. The anchor has different versions which allow it to be attached to the tendon prior to insertion into the bone tunnel, or be inserted between tendon arms when the surgical procedure dictates. The resulting tendon to bone compression allows for the firm fixation in a manner markedly simpler than traditional techniques. A modification of this anchor can also allow the anchor to grasp and hold suture. This variation facilitates the technique for knotless rotator cuff repair.

An arthroscopic meniscal tear repair device includes a catch needle and a transfer needle. which are pierced into a torn meniscus and advanced past the tear. Suture is transferred by a suture needle from the transfer needle through the meniscus and into the catch needle. The catch needle has an internal mechanism that retains the suture. The suture needle is then retracted back to its home position inside the transfer needle, leaving the free end of the suture across the meniscus and in the catch needle. The device is then retracted out of the meniscus, leaving behind a stitch across the meniscal tear inside the meniscus . A pre-tied knot of suture is then slid down the device and cinched up using a knot pusher having a dilation tip, thus completing the repair.

SELF-TAPPING BIOCOMPATIBLE INTERFERENCE BONE SCREW
A biocompatible interference screw for soft tissue or bone-to-bone fixation comprises a screw body extending from a screw head to a distal tip of the screw. The screw body has an outer surface, and comprises polyether-ether-ketone (PEEK) material. Advantageously, the body outer surface has a textured surface finish for substantially improving pull-out strength of the interference screw. The textured surface finish is textured, in preferred embodiments, with a minimum of approximately 16 micro inches of surface roughness. The screw head comprises a tapered square keyhole for receiving a distal end of a driver instrument. The screw comprises a series of threads, which have a relatively smooth profile, in order to prevent graft tissue laceration as the screw is being inserted. The distal tip of the screw body comprises a narrow tip, and a distal end of the screw body is angled inwardly toward the narrow distal tip.

A soft tissue fixation system, most typically applicable to orthopedic joint repairs, such as anterior cruciate ligament (ACL) knee repair procedures, comprises an implant which is placeable in a tunnel disposed in a portion of bone, wherein the tunnel is defined by walls comprised of bone. A first member is deployable outwardly to engage the tunnel walls for anchoring the implant in place in the tunnel, and a second member is deployable outwardly to engage tissue material to be fixed within the tunnel. The second member also functions to move the tissue material outwardly into contact with the tunnel walls to promote tendon-bone fixation. Extra graft length is eliminated by compression of the tendon against the bone at the aperture of the femoral tunnel, which more closely replicates the native ACL and increases graft stiffness. The inventive device provides high fixation of tendon to bone and active tendon-bone compression. Graft strength has been found to be greater than 1,000 N (Newtons), which is desirable for ACL reconstruction systems.

Suture management and tensioning devices and methods for soft tissue reconstruction or bone-to-bone fixation
An adjustable, stand-alone tensioning system requires no additional fixturing, weights, or bone surface modification, and allows a single practitioner to provide an adjustable and repeatable tension to a soft tissue graft, and to install the final fixation implant. Its design facilitates introduction of the suture component of the graft into the tensioning process by simplifying retention of the suture. An even, regulated and reproducible tension is easily achieved without requiring the practitioner to manually pull on the suture strands to maintain graft tension.

ARTHROSCOPIC SOFT TISSUE PLICATION SYSTEMS AND METHODS
A system and method for repairing soft tissue comprises introducing an instrument having a shaft into an operative site, such as a human shoulder. Then, a flexible grasper is advanced from the instrument to capture a portion of soft tissue. The flexible grasper is then retracted so that the captured tissue lies in a pathway for a needle in the instrument. The needle is advanced along the pathway through the captured tissue, and then a portion of suture is captured with the needle, distally of the captured tissue. The needle is retracted proximally through the captured tissue, to thereby pass the suture therethrough and plicate the tissue. The plicated tissue is then released from the grasper.

Devices, systems and methods for material fixation
A material fixation system is particularly adapted to improve the tendon-to-bone fixation of hamstring autografts, as well as other soft tissue ACL reconstruction techniques. The system is easy to use, requires no additional accessories, uses only a single drill hole, and can be implanted by one person. Additionally, it replicates the native ACL by compressing the tendons against the aperture of the tibial tunnel, which leads to a shorter graft and increased graft stiffness. It is adapted to accommodate single or double tendon bundle autografts or allografts. It also provides pull out strength measured to be greater than 1000 N.
