Claim Text:
1. A device for creating a seal in a blood vessel comprising: a low profile shaft assembly configured for insertion into a vessel, said shaft assembly having an expandable region at the distal end of the shaft assembly and a sealing membrane spanning said expandable region, said expandable region being deployable from a first low-profile position to a second expanded position and having an area in its second expanded position corresponding to an area of a blood vessel that is large enough to accommodate multiple anastomosis sites, wherein said expandable region in its second expanded position has a hexagonal shape; a clamping member positioned generally opposite to and moveable towards said expandable region, said clamping member having a distal end shape corresponding to said expandable region in its second expanded position; and wherein the expandable region further comprises bowing segments that bow outwardly from the shaft assembly when the expandable region is deployed from the first low-profile position to the second expanded position, the expandable region comprises an upper proximal hole, an upper distal hole and a first slit extending longitudinally between the upper proximal hole and the upper distal hole on an upper surface of the expandable region, and a lower proximal hole, a lower distal hole and a second slit extending longitudinally between the lower proximal hole and the lower distal hole on a lower surface of the expandable region, wherein the upper proximal hole and the lower proximal hole are offset from one another; and wherein the upper distal hole and the lower distal hole are offset from one another such that the bowing segments are biased toward the clamping member when the expandable region is deployed from the first low-profile position to the second expanded position.
