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.
