Delivery system and method for deploying an endovascular prosthesis
First Claim
1. An apparatus for delivering an endovascular prosthesis within a blood vessel, said apparatus comprising a sheath with a first end, a second end, an inner lumen for receiving an endovascular prosthesis, and an outer lumen for receiving a guide wire, said inner lumen extending along a central axis between said first end and said second end, said outer lumen being radially spaced from said inner lumen and extending along an outer axis between said ends;
- anda nosecone connected to a stiff wire, said nosecone having an outer diameter that is greater than the diameter of a first opening in said first end of said sheath.

Abstract
The present invention relates to an apparatus (300) for delivering an endovascular prosthesis within a blood vessel. The apparatus (300) includes a sheath (302) having a first end (310), a second end (308), an inner lumen (316) for receiving an endovascular prosthesis, and an outer lumen (322) for receiving a guide wire. The inner lumen (316) extends along a central axis (313) between the first end (310) and the second end (308). The outer lumen (322) is radially spaced from the inner lumen (316) and extends along an outer axis (323) between the ends (308 and 310).
