Branched stent graft system

摘要

An endovascular prosthetic system comprising an prosthetic device with a major lumen extending therethrough, a major wall, at least one opening in the major wall; at least one branch extending into the major lumen of the prosthetic device having a minor lumen, a minor wall, and a fenestration in the minor wall in communication with the major lumen; and at least one guide wire extending through the fenestration and out of the prosthesis through the opening.

主权项

1. An endovascular prosthesis delivery system for implanting a prosthetic device, the endovascular prosthetic delivery system comprising:
a delivery catheter; a primary prosthesis disposed on the delivery catheter, the primary prosthesis comprising:
a major lumen;a socket for receiving a secondary prosthesis, which secondary prosthesis is deployed in a branch artery, the socket having at least a portion that extends into the major lumen, said portion being angled in a proximal direction so as to direct blood flowing from the heart to the branch artery; anda fenestration in the wall of the socket sized to accommodate a preloaded guide wire;where the guidewire is preloaded directly within the major lumen of the primary prosthesis disposed on the delivery catheter prior to implantation and passes through the major lumen from a distal location, through the fenestration, and into the socket, said guide wire being configured to facilitate placement of the secondary prosthesis in the branch artery.
