Corewire actuated delivery system with fixed distal stent-carrying extension
First Claim
1. A stent delivery system comprising:
- a self-expanding stent;
an inner wire, an outer sleeve, the inner wire slidingly received within the sleeve, an extension member, a connection being provided between a distal portion of the sleeve and the extension member;
a restraint holding the stent collapsed over a distal wire portion of the extension member; and
a bridge segment connecting the restraint to the inner wire.

Abstract
Medical device and methods for delivery or implantation of prostheses within hollow body organs and vessels or other luminal anatomy are disclosed. The subject technologies may be used in the treatment of atherosclerosis in stenting procedures. For such purposes, a self-expanding stent is deployed in connection with an angioplasty procedure with a corewire actuated delivery system having a fixed distal stent-carrying extension. Withdrawal of the corewire retracts a restraint freeing the stent from a collapsed state, whereupon the stent assumes an expanded configuration set in apposition to the interior surface of a vessel lumen in order to help maintain the vessel open.
