RECONFIGURABLE STENT-GRAFT DELIVERY SYSTEM AND METHOD OF USE
First Claim
1. A reconfigurable stent-graft delivery system comprising:
- a tubular sheath component defining a lumen from a proximal end to distal end thereof that is reconfigurable from a multi-lumen delivery catheter configuration to a delivery sheath configuration,wherein in the multi-lumen delivery catheter configuration a proximal portion of the sheath component lumen is divided into a plurality of working lumens and a distal portion of the sheath component lumen includes a stent-graft delivery area for compressing a main stent-graft prosthesis in a delivery configuration therein, andwherein in the delivery sheath configuration the proximal portion of the sheath component lumen is not divided into the plurality of working lumens.

Abstract
A reconfigurable delivery system is disclosed having a multi-lumen delivery catheter configuration that permits the delivery and staged release of a self-expanding main vessel stent-graft and a delivery sheath configuration that permits the introduction of various medical devices for the delivery and implantation of various branch vessel stent-grafts that are to be mated with the main vessel stent-graft. A method is disclosed wherein the delivery system is first used in the multi-lumen delivery catheter configuration to deliver and release a main vessel stent-graft that is configured for placement in the abdominal aorta for treatment of short-neck infrarenal, juxtarenal, and/or suprarenal aneurysms and then used in the delivery sheath configuration to facilitate the delivery of branch vessel stent-grafts that are configured to extend from the main vessel stent-graft into a respective renal artery.

11. A stent-graft delivery system comprising:
-
a handle component; a tubular sheath component having a proximal end operably attached to the handle component and defining a lumen from the proximal end to distal end thereof; and a middle member component removably coupled to the delivery system, the middle member component having a middle member shaft that extends within and divides at least a proximal portion of the sheath component lumen into a plurality of working lumens when the delivery system is in a multi-lumen delivery catheter configuration. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
