Abstract
A method for relining a blood vessel. A tubular liner of biocompatible material, having an anchoring device connected to a distal end thereof, is inserted into a blood vessel using a delivery system. The delivery system may include a removable hub that is initially attached to the tubular liner and a hollow tip that is positioned over the anchoring device. The tip is positioned at a predetermined location and the anchoring device is removed from the tip, contacting a wall of the blood vessel. The liner is attached to the blood vessel following separation from the hub and removal of the delivery system from the blood vessel.
Claims4
A method for relining a blood vessel utilizing an apparatus comprising a tubular liner of biocompatible material having a proximal end and a distal end, an anchoring device connected to said distal end of said tubular liner, wherein said proximal end of said tubular liner extends beyond said anchoring device and is configured for attachment to said blood vessel, and a delivery system comprising a removable hub attached to said proximal end of said tubular liner and a hollow tip positioned over said distal end of said tubular liner, said tip being connected to a proximal end of said delivery system, wherein at least a portion of said anchoring device is positioned within said tip, comprising the steps of:
- inserting said tip and distal end of said tubular liner into said blood vessel;
- positioning said tip at a predetermined location;
- removing said liner and said anchoring device from said tip, whereupon said anchoring device comes into contact with a wall of said blood vessel;
- removing said hub from said proximal end of said liner;
- removing said delivery system from said blood vessel;
- and
- attaching said proximal end of said liner to said blood vessel.
