First Claim
Patent Images
1. 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 proximal and distal ends and an exchange port extending through the wall and providing access to the first passageway;
a distal tip member slideably disposed in the distal end of the elongate tubular member, the 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 a self-expandable prosthetic device can be disposed, the second proximal end disposed distal to the exchange port and defining a proximal surface;
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.

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 disposed at least partially within the distal end of the passageway. A pusher is disposed in the passageway to effect axial movement of the distal tip member.
