DELIVERY SYSTEM AND METHOD OF USE FOR DEPLOYMENT OF SELF-EXPANDABLE VASCULAR DEVICE

摘要

A delivery system that includes a catheter, a balloon, a self-expanding prosthesis, and a sheath. The sheath including an opening in a wall of the sheath that initiates rupturing of the sheath so that the self-expanding prosthesis may move from its compressed state to its expanded state. Additionally, a distal end portion of the balloon that is distal to a distal end of the sheath includes an enlarged diameter portion, the enlarged diameter portion having approximately the same outer diameter as an outer diameter of the sheath when the self-expanding prosthesis is in its compressed state, and the enlarged diameter portion being the maximum outer diameter of the balloon when the self-expanding prosthesis is in its compressed state.

1. A delivery system comprising:
a catheter having a distal portion and a proximal portion; a balloon disposed on the distal portion of the catheter; a self-expanding prosthesis disposed on at least a portion of the balloon, the self-expanding prosthesis having a compressed stated and an expanded state; and a sheath coupling the self-expanding prosthesis to the balloon when the self-expanding prosthesis is in its compressed state, wherein: the sheath includes an opening in a wall of the sheath that initiates rupturing of the sheath so that the self-expanding prosthesis may move from its compressed state to its expanded state, and a distal end portion of the balloon that is distal to a distal end of the sheath includes an enlarged diameter portion, the enlarged diameter portion having approximately the same outer diameter as an outer diameter of the sheath when the self-expanding prosthesis is in its compressed state, and the enlarged diameter portion being the maximum outer diameter of the balloon when the self-expanding prosthesis is in its compressed state.
