The collapsible penetration locators provide the insertion sheath with a small outer diameter and the added functionality of precise location indicator. The collapsible penetration locators comprise thin membranes that collapse upon insertion of a sealing device or vascular instrument into the insertion sheath. The insertion sheath includes a reinforced wall according to some embodiments, with a coiled or braided filament for reinforcement.
An internal tissue puncture closure method and apparatus. The method and apparatus provide a folded sealing plug (218) that provides more surface area than conventional plugs to more fully cover and seal an external situs of an internal tissue puncture. The folded sealing plug (218) may have a weave pattern that tends to cause the sealing plug to corkscrew into the internal tissue puncture as it is compressed toward an anchor (114) placed inside of the tissue puncture.
The present invention provides a method and apparatus for sealing a subcutaneous tissue puncture. The method and apparatus increases the reliability of device function by creating a multi-level anchor nest in a carrier tube of a tissue puncture closure device. The multi-level nest allows an insertion sheath or other deployment member to slide between the carrier tube and the anchor to rotate and deploy the anchor within an artery or other lumen.
A sealing device incorporating a block and tackle for assisting in sealing an internal tissue puncture with an internal and external component. The block and tackle provides a mechanical advantage multiplying an initial force to facilitate compression of the internal and external component together across the internal tissue puncture. The internal and external components may be an anchor and collagen sponge, respectively. The internal tissue puncture is generally an arteriotomy intentionally created in order to perform a vascular procedure. The ability to exert a greater compression force across the arteriotomy eliminates a tamping tube common to prior internal tissue puncture closure devices, and also eliminates additional steps heretofore common to sealing internal tissue punctures. The steps eliminated by application of the principles described herein include tamping the collagen sponge, attaching a tamping spring between a tamping tube and a filament connecting the anchor to the collagen sponge, and later removing the tamping spring.
A method and apparatus for sealing a puncture or incision formed percutaneously in tissue separating two internal portions of the body of a living being with an anchor, a sealing plug and a filament connecting the anchor and sealing plug. The method and apparatus provide for automatic tamping and/or cinching of the sealing plug when the apparatus is withdrawn from the puncture site. The automatic tamping and/or cinching is facilitated by transducing a motive force generated by the withdrawal of the apparatus into a tamping and/or cinching force.

An internal tissue puncture closure method and apparatus. The method and apparatus provide a locking device for compressing and holding an external component such as a collagen sponge at a puncture situs. The locking device facilitates compression of the external component in a first direction, but prevents or locks against retraction.
The present invention involves an automatic suture locking device useable with vascular closure device. The suture locking device includes a housing and a locking mechanism. The locking mechanism has locked and unlocked positions. In the locked position, a suture pathway through the mechanism is sufficiently tortuous to prevent free suture movement.

A vascular closure device including a sheath with one or more orifices therein to detect blood flow, indicating that the sheath has entered an artery and the relative position of the sheath within the artery. Thus, the sheath can be moved and positioned relative to the artery without having to completely extract the sheath from the artery after initial penetration.
