Endovascular graft
First Claim
1. A bifurcated endovascular graft system comprising:
- a main tubular body portion of biocompatible material having a proximal end and an opposed distal end, the proximal end comprising a proximal neck portion having an open end;
the main body portion further comprising;
an inflatable cuff permanently secured to the proximal neck portion of the main tubular body portion proximal to the open end of the proximal neck portion and extending around a circumference of the proximal neck portion; and
a non-inflatable expansion member having a generally cylindrical shape secured to a portion of the proximal neck portion of the main tubular body portion between the inflatable cuff and the end of the proximal neck portion;
a first tubular bifurcated portion of biocompatible material having opposed open ends and secured at the distal end of the main body portion;
a second tubular bifurcated portion of biocompatible material having opposed open ends and secured at the distal end of the main body portion;
wherein the first and second tubular bifurcated portions further comprise circumferential inflatable channels; and
wherein at least one of the circumferential inflatable channels of the first and second tubular bifurcated portions extends only partially around a circumference of the first and second tubular bifurcated portions.

Abstract
An endovascular graft, which is configured to conform to the morphology of a vessel to be treated, includes a tubular ePTFE structure; an inflatable ePTFE structure disposed over at least a portion of the ePTFE tubular structure; and an injection port in fluid communication with the inflatable ePTFE structure for inflation of the inflatable ePTFE structure with an inflation medium. The inflatable ePTFE structure may be longitudinally disposed over the tubular ePTFE structure. The ePTFE structure may be a bifurcated structure having first and second bifurcated tubular structures, where the inflatable ePTFE structure is disposed over at least a portion of the first and second bifurcated tubular structures.
