1. An apparatus for repairing a damaged area of a body vessel, comprising:

  • a resilient sleeve adapted for placement within the vessel and having a length sufficient to bridge the damaged area of said vessel, said sleeve being radially collapsible to a collapsed condition and capable of thereafter expanding to its original uncollapsed condition, said sleeve having an outside diameter sufficient to form an interference fit between the outer wall of the sleeve and the inner wall of the vessel throughout substantially the entire length of the sleeve;

    percutaneous insertion means for inserting the sleeve into the body vessel, said insertion means including a thin walled sheath for retaining said sleeve in its collapsed condition against radially outward pressure exerted thereby during placement of said sleeve within said vessel, said insertion means being removable after placement of said sleeve within said vessel;

    said thin walled sheath being provided at the end of an elongated flexible catheter adapted for percutaneous placement within said vessel for transporting said sleeve to the location of the damaged area of said vessel, said catheter and sheath being removable from said vessel while said sleeve is retained at the location of the damaged area of said vessel for allowing said sleeve to return to its original unexpanded condition upon withdrawal of said catheter and sheath; and

    collapsing means for collapsing said sleeve, comprising a thread adapted to be looped about the circumference of said sleeve throughout substantially the entire length of said sleeve, and to be tightened about said sleeve so as to collapse said sleeve onto said catheter for subsequent insertion of said sleeve into said thin walled sheath.
