Abstract:
1. A method of both treating a stenosed region of the interior surface of a blood vessel and inducing repair of the region, comprising: introducing a device into the blood vessel, the device including a tubular first member at least partially comprised of an extracellular matrix material, said tubular first member having first and second ends, said tubular first member being unsupported between said first end and said second end and having barbs which perforate said tubular first member and enter tissue of the blood vessel; inserting said device into said vessel so that said barbs are upstream of said second end of said tubular first member and of said stenosed region and so that said tubular first member shields at least a portion of the stenosed region of the interior surface from blood flow; and introducing a dilation balloon into said tubular first member after inserting said device, and inflating at least a portion of said balloon against said unsupported tubular first member so that said balloon expands said unsupported tubular first member and the stenosed region and maintains the stenosis out of blood flow; wherein when said balloon has been removed, said unsupported tubular first member remains adjacent with the stenosed region and is effective to induce repair of the stenosed region.
