Endoprosthesis delivery systems with deployment aids

An endoprosthesis delivery system comprising:

• an expandable endoprosthesis having at least one apex at an end;
• at least one guiding flexible element disposed over the at least one apex;
• and
• a covering member about the endoprosthesis, wherein the at least one guiding flexible element impedes the covering member from catching on the at least one apex.

An endoprosthetic device for treating a body lumen, the endoprosthetic device comprising:

• a compressible material coupled to a distal section of an elongate member;
• an expandable endoprosthesis at least partially embedded in the compressible material, the endoprosthesis comprising a distal stent element, the distal stent element forming a series of apices, each of the apices at least partially defining an opening;
• a plurality of flexible members, at least one of the plurality of flexible members overlaying one apex, each flexible member further inserted through one of the openings, each flexible member further extending between the compressible material and the endoprosthesis;
• and
• a plurality of fibers woven about an exterior surface of the endoprosthesis and constraining the endoprosthesis in a constrained diameter, the plurality of fibers capable of unraveling from the endoprosthesis such that at least one of the plurality of fibers is guided over at least one of the apices by at least one of the plurality of flexible members.

An endoprosthesis delivery system comprising:

• an elongate member;
• a slip resistant portion on an outer surface of the elongate member;
• a tubular endoprosthesis having a distal end and a proximal end and located about the elongate member adjacent the slip resistant portion;
• and
• a sheath disposed about the tubular endoprosthesis and extending beyond at least one of the distal end and the proximal end, wherein the slip resistant portion is adapted to impede bunching of the sheath during deployment.

An endoprosthesis delivery system comprising:

• an elongate member;
• a tubular endoprosthesis comprising an edge located at a distal section of the elongate member;
• an end cap adjacent to the edge;
• and
• a covering member comprising a plurality of fibers, the covering member at least partially covering the endoprosthesis, the covering member extending over at least a portion of the end cap.

An endoprosthesis delivery system comprising:

• an elongate member;
• a tubular endoprosthesis comprising an edge located at a distal section of the elongate member;
• an end cap adjacent the edge;
• and
• a covering member, the covering member extending over at least a portion of the end cap, wherein the end cap is adapted to at least partially conform to the edge.
