DEVICE AND METHOD FOR TACKING PLAQUE TO BLOOD VESSEL WALL
A tack device for holding plaque against blood vessel walls in treating atherosclerotic occlusive disease can be formed as a thin, annular band of durable, flexible material. The tack device may also have a plurality of barbs or anchoring points on its outer annular periphery. The annular band can have a length in the axial direction of the blood vessel walls that is about equal to or less than its diameter as installed in the blood vessel. A preferred method is to perform angioplasty with a drug eluting balloon as a first step, and if there is any dissection to the blood vessel caused by the balloon angioplasty, one or more tack devices may be installed to tack down the dissected area of the blood vessel surface.

A plaque tack can be used for holding plaque against blood vessel walls such as in treating atherosclerotic occlusive disease. The plaque tack can be formed as a thin, annular band for holding loose plaque under a spring or other expansion force against a blood vessel wall. Focal elevating elements and/or other features, such as anchors, can be used to exert a holding force on a plaque position while minimizing the amount of material surface area in contact with the plaque or blood vessel wall and reducing the potential of friction with the endoluminal surface. This approach offers clinicians the ability to perform a minimally invasive post-angioplasty treatment and produce a stent-like result without using a stent.

A plaque tack can be used for holding plaque against blood vessel walls such as in treating atherosclerotic occlusive disease. The plaque tack can be formed as a thin, annular band for holding loose plaque under a spring or other expansion force against a blood vessel wall. Focal elevating elements and/or other features, such as anchors, can be used to exert a holding force on a plaque position while minimizing the amount of material surface area in contact with the plaque or blood vessel wall and reducing the potential of friction with the endoluminal surface. This approach offers clinicians the ability to perform a minimally invasive post-angioplasty treatment and produce a stent-like result without using a stent.

SYSTEMS AND METHODS FOR ATTACHING RADIOPAQUE MARKERS TO A MEDICAL DEVICE
A radiopaque marker can be attached to a medical device, such as an intravascular device. The radiopaque marker can be pre-formed, or formed from a spool of material. The radiopaque marker can be placed in, on, or at a spot for receiving the radiopaque marker. The radiopaque marker can then be attached to the medical device.

A plaque tack can be used for holding plaque against blood vessel walls such as in treating atherosclerotic occlusive disease. The plaque tack can be formed as a thin, annular band for holding loose plaque under a spring or other expansion force against a blood vessel wall. Focal elevating elements and/or other features, such as anchors, can be used to exert a holding force on a plaque position while minimizing the amount of material surface area in contact with the plaque or blood vessel wall and reducing the potential of friction with the endoluminal surface. This approach offers clinicians the ability to perform a minimally invasive post-angioplasty treatment and produce a stent-like result without using a stent.

Device and method for tacking plaque to a blood vessel wall
A tack device for holding plaque against blood vessel walls in treating atherosclerotic occlusive disease is formed as a thin, annular band of durable, flexible material having a plurality of barbs or anchoring points on its outer annular periphery. The annular band has a length in the axial direction of the blood vessel walls that is about equal to or less than its diameter as installed in the blood vessel. In a preferred embodiment, the tack device is formed as a compressible metallic mesh band having outer barbs on outer sides of the mesh structure. Another embodiment may have a plurality of compressible mesh bands may be formed spaced apart coaxially from each other and connected by longitudinally extending bridge members. A preferred method is to perform angioplasty with a drug eluting balloon as a first step, and if there is any dissection to the blood vessel caused by the balloon angioplasty, one or more tack devices may be installed to tack down the dissected area of the blood vessel surface, in order to avoid the need to install a stent and thereby maintain a ‘stent-free’ environment.
A plaque tack device for treating atherosclerotic occlusive disease is formed as a thin, annular band of durable, flexible material having a plurality of barbs or anchoring points on its outer periphery for preventing it from being dislodged. The plaque tack may be used with a balloon angioplasty procedure or as a de novo treatment for blood vessel blockage to reopen the vessel lumen for desired blood flow. It has a width that is small relative to its diameter, to minimize the amount of foreign structure placed in the blood vessel. One or more tacks may be applied in positions along a plaque accumulation site as needed to stabilize the site and/or hold pieces of plaque out of the way of blood flow. The barbs of the tack may be pressed into the plaque and/or blood vessel walls by balloon expansion. Related methods of deployment and delivery devices are provided for insertion of the plaque tack in a compressed state into the blood vessel and expanding it back to its annular shape for holding plaque against the blood vessel walls.
