Abstract

One preferred embodiment includes a stent delivery system including a retractable sheath and an outer stability sheath. The stability sheath freely rotates relative to the retractable sheath, relieving compression forces caused by twisting of stability sheath in when in a tortuous conformation.

Claims

1. A stent delivery system, comprising:

a first tubular member having a distal end sized and shaped to receive a stent;

a second tubular member being longitudinally slidable over said first tubular member;

a third tubular member being at least partially disposed over said second tubular member, said third tubular member being rotatable relative to said first tubular member and to said second tubular member;

a handle body coupled to said second tubular member to retract said second tubular member relative to said first tubular member.

2. A stent delivery system, comprising:

a first tubular member having a distal end sized and shaped to receive a stent;

a second tubular member being longitudinally slidable over said first tubular member;

a third tubular member being at least partially disposed over said second tubular member, said third tubular member being longitudinally compressible relative to said first tubular member and to said second tubular member;

a handle body coupled to said second tubular member to retract said second tubular member relative to said first tubular member.

3. A stent delivery system, comprising:

a first tubular member having a distal end sized and shaped to receive a stent;

a second tubular member being longitudinally slidable over said first tubular member;

a third tubular member being at least partially disposed over said second tubular member;

a handle body coupled to said second tubular member to retract said second tubular member relative to said first tubular member;

said third tubular member being releasably bonded to said handle body.
