Balloon flareable branch vessel prosthesis and method
First Claim
1. A stent graft system for intraluminal deployment in an aorta and a branch vessel comprising:
- an aorta stent graft for deployment within the aorta and defining a lumen for the passage of blood therethrough, and having a fenestration positioned and sized so as to allow blood to flow to a contiguous branch vessel;
a branch vessel prosthesis having a tubular portion and a flaring portion, such that, when deployed, the flaring portion is located within the lumen of the aorta stent graft and the tubular portion passes through the fenestration and into the branch vessel;
a balloon expansion catheter having first and second balloons,wherein the first balloon is aligned substantially with the flaring portion and the second balloon is aligned substantially with the tubular portion such that inflation of the first balloon flares the flaring portion and inflation of the second balloon expands the tubular portion, andwherein the second balloon is less compliant than the first balloon.

Abstract
A stent graft system for intraluminal deployment in an aorta and a branch vessel that includes an aorta stent graft for deployment within the aorta and defining a lumen for the passage of blood therethrough, and having a fenestration positioned and sized so as to allow blood to flow to a contiguous branch vessel. The system also includes a branch vessel prosthesis, preferably a stent graft, having a tubular portion and a flaring portion, such that, when deployed, the flaring portion is located within the lumen of the aorta stent graft and the tubular portion passes through the fenestration and into the branch vessel. A balloon expansion catheter expands the tubular portion and flare the flaring portion. The expansion of the tubular portion and the flaring of the flaring portion may occur sequentially or simultaneously.

8. A method of deploying a stent graft system in an aorta and a branch vessel comprising:
-
deploying an aorta stent graft within the aorta, which defines a lumen for the passage of blood therethrough, and comprises a fenestration positioned and sized so as to allow blood to flow to a contiguous branch vessel; deploying a branch vessel prosthesis, which comprises a tubular portion and a flaring portion, so that the flaring portion is located within the lumen of the aorta stent graft and the tubular portion passes through the fenestration and into the branch vessel; aligning a single balloon expansion catheter having first and second balloons such that the first balloon is aligned substantially with the flaring portion and the second balloon is aligned substantially with the tubular portion, wherein the second balloon is less compliant than the first balloon; and inflating the first balloon to flare the flaring portion and inflating the second balloon to expand the tubular portion. - View Dependent Claims (9, 10, 11, 12, 13, 14, 17, 18)
