Abstract
Abstract A graft and stent assembly is securable to a first sidewall of a blood vessel having an arteriotomy defined therein, with the blood vessel having a flow of blood therein. The assembly includes a graft which has an orifice. The graft further has an end portion which is positionable within the blood vessel and substantially adjacent to a portion of the first sidewall of the blood-vessel which substantially surrounds the arteriotomy. The assembly further includes a stent which has a second sidewall. The stent is positionable within the blood vessel and in contact with the end portion of the graft so as to secure the end portion of the graft between the first sidewall of the blood vessel and the stent. The orifice of the graft is positioned relative to the second sidewall of the stent so that the flow of blood must pass through the second sidewall of the stent in order to advance through the orifice of the graft.

Independent Claim
156 words
A graft and stent assembly which is securable to a first sidewall of a blood vessel having an arteriotomy defined therein, the blood vessel having a flow of blood therein, comprising: a graft having an orifice, said graft further having an end portion which is positionable within the blood vessel and substantially adjacent to a portion of the first sidewall of the blood vessel which substantially surrounds the arteriotomy; and a stent having a second sidewall, said stent being positionable within the blood vessel and in contact with the end portion of said graft so as to secure the end portion of said graft between the first sidewall of the blood vessel and said stent, wherein the orifice of said graft is positioned relative to the second sidewall of said stent so that the flow of blood must pass through the second sidewall of said stent in order to advance through the orifice of said graft.
Claim 2
Dependent Claim
156 words
A graft and stent assembly which is securable to a first sidewall of a blood vessel having an arteriotomy defined therein, the blood vessel having a flow of blood therein, comprising: a graft having an orifice, said graft further having an end portion which is positionable within the blood vessel and substantially adjacent to a portion of the first sidewall of the blood vessel which substantially surrounds the arteriotomy; and a stent having a second sidewall, said stent being positionable within the blood vessel and in contact with the end portion of said graft so as to secure the end portion of said graft between the first sidewall of the blood vessel and said stent, wherein the orifice of said graft is positioned relative to the second sidewall of said stent so that the flow of blood must pass through the second sidewall of said stent in order to advance through the orifice of said graft.
