First Claim
Patent Images
1. A device for delivering a stent to a patient for implantation comprising:
- (i) a first tubular structure having a proximal end, a distal end, and a lumen extending therethrough;
(ii) a second tubular structure having a proximal end, a distal end, and a lumen extending therethrough;
(iii) the stent having a proximal end and a distal end;
(iv) a stent-engaging member;
(v) a distal tip; and
(vi) a handle positioned over a portion of the proximal end of the first tubular structure, wherein the handle is funnel-shaped and configured to receive the distal end of the stent therein,wherein said stent is disengagedly coupled to the second tubular structure via the stent-engaging member, wherein the second tubular structure is positioned within the first tubular structure and the stent is movable with respect to the first tubular structure, wherein the stent is positioned external to the second tubular structure, wherein the stent-engaging member is positioned between the second tubular structure and the stent, wherein the stent-engaging member is positioned in its entirety internal to the stent, wherein the distal tip is configured to attach to the distal end of the second tubular structure after insertion of the stent into the device, and wherein the stent-engaging member is selected from the group consisting of an annular protuberance, a flat holder, and an anchor.
