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.
Claims16
A stent delivery system, comprising:
- an inner member having a distal end sized and shaped to receive a stent;
- a longitudinally slidable outer member disposed over the inner member and the stent;
- a handle connected to the outer member, the handle including a retraction mechanism designed to retract the outer member into the handle;
- and
- a stability sheath disposed over the outer member, wherein the stability sheath is rotatable relative to the inner member and the outer member, the stability sheath comprising:
- a proximal end coupled to the handle at an internal section of the handle;
- and
- a disk coupled to the proximal end, wherein the disk is disposed in a circular cavity in the handle to permit free rotation of the stability sheath while preventing axial movement of the stability sheath.
