Delivery system for endoluminal implant
First Claim
1. A delivery system for delivering an endoluminal implant to a distal deployment location inside a body lumen from a proximal access location outside the body lumen, the delivery system comprising:
- the implant having a proximal end and a distal end;
a catheter comprising, a catheter tip, the catheter tip having a proximal end located adjacent the implant distal end and attached to a central core slideably disposed relative to the implant;
the catheter tip proximal end comprising a docking section adapted to releasably engage a portion of the implant, the docking section comprising a pocket adapted to releasably contain a limited length of one end of the compressed implant inserted therein, the pocket comprising an annular pocket having an inner wall located radially inward of the compressed implant and an outer wall located radially outward of the compressed implant, the inner wall and the outer wall both terminating at a substantially same axial location relative to the implant.

Abstract
A delivery system for delivering an endoluminal implant to a distal deployment location inside a body lumen from a proximal access location outside the lumen. The system comprises the implant, a catheter, and a slidable sheath having an advanced position in which the sheath covers the implant and a retracted position in which the implant is exposed. The catheter comprises a stabilizer having a distal end adjacent the implant proximal end and/or a catheter tip attached to a central core slideably disposed relative to the implant and having a proximal end adjacent the implant distal end. The catheter tip proximal end and/or the stabilizer distal end comprises a docking section adapted to releasably engage a portion of the implant. Each docking section has an engagement geometry comprising a flared engagement surface that extends inside a short axial length of the implant or a pocket having a bottleneck geometry.
