Claims
- 1. A stent delivery system comprising:
a catheter including a stent mounting region; a stent disposed about the stent mounting region of the catheter, the stent having a distal end and a proximal end, the stent further having an unexpanded state and an expanded state, and at least one stent retaining sleeve having a first end and a second end,
the first end overlying an end of the stent when the stent is in the unexpanded state, the second end engaged to at least a portion of the catheter adjacent to the stent mounting region; the at least one stent retaining sleeve being at least partially composed of at least one hydrophilic elastomeric material.
- 2. The stent delivery catheter of claim 1 wherein the at least one hydrophilic elastomeric material is TECOPHILIC.
- 3. The stent delivery catheter of claim 1 wherein the at least one hydrophilic elastomeric material is HYDROTHANE.
- 4. The stent delivery catheter of claim 1 wherein the at least one hydrophilic elastomeric material is at least partially comprised of hydrophilic polyurethane.
- 5. The stent delivery catheter of claim 1 wherein the at least one hydrophilic elastomeric material is at least partially comprised of hydrophilic polyesters.
- 6. The stent delivery catheter of claim 1 wherein the at least one hydrophilic elastomeric material is at least partially comprised of hydrophilic polyamides.
- 7. The stent delivery catheter of claim 1 where in the at least one hydrophilic elastomeric material has a predetermined hardness, the predetermined hardness being selected from a durometer value between about 80A-72D.
- 8. A stent retaining sleeve for retaining in an expanded state at least one end of a stent on a balloon catheter comprising a tubular member having a first end and a second end:
the first end constructed and arranged to overlay an end of a stent, the second end constructed and arranged to be in contact with at least a portion of a catheter adjacent to a stent mounting region; at least a portion of the tubular member composed of at least one hydrophilic elastomer material.
- 9. A stent delivery system comprising:
a catheter including a stent mounting region; a stent disposed about the stent mounting region of the catheter, the stent having a distal end and a proximal end, the stent further having an unexpanded state and an expanded state, and at least one hydrophilic elastomeric stent retaining sleeve having a first end and a second end,
the first end overlying an end of the stent when the stent is in the unexpanded state, the second end engaged to at least a portion of the catheter adjacent to the stent mounting region.
