Abstract
Exchangeable delivery systems, methods of making delivery systems, and methods of delivering a self-expandable prosthetic device are provided. Delivery systems according to embodiments of the invention include an elongate tubular member defining a passageway with a distal end defining an exchange port, and a distal tip member slideably disposed partially within the distal end of the passageway.
Claims13
A delivery system for placing a self-expandable prosthetic device within a body vessel, said delivery system comprising:
- an elongate tubular member comprising a circumferential wall and having first proximal and distal ends, the elongate tubular member defining a first passageway extending between the first proximal and distal ends and an exchange port extending through the wall and providing access to the first passageway;
- a distal tip member having second proximal and distal ends, defining a second passageway extending between the second proximal and distal ends, and defining a mounting region about which said self-expandable prosthetic device can be disposed, the second proximal end defining a proximal surface and being slideably disposed within the first passageway;
- a pusher disposed within the first passageway and comprising a third distal end adapted to interact with the proximal surface of the distal tip member;
- and
- means for retaining the second proximal end of the distal tip member within the first passageway;
- wherein the second proximal end of the distal tip member defines a projection directed radially outward;
- wherein the means for retaining the second proximal end of the distal tip member within the first passageway comprises a track defined by the wall of the elongate tubular member, wherein the track terminates proximal to the distal end of the elongate tubular member;
- and
- wherein the projection is slideably disposed within the track;
- wherein the second proximal end of the distal tip member further defines a second projection directed radially outward;
- wherein the means for retaining the second proximal end of the distal tip member within the first passageway further comprises a second track defined by the wall of the elongate tubular member, wherein the second track terminates proximal to the distal end of the elongate tubular member;
- and
- wherein the second projection is slideably disposed within the second track.
