Abstract
Abstract An implantable textile prosthesis which is anatomically curved to substantially match the natural curvature of the aortic arch in a human being or patient is provided. The first woven section is arched define an apical region and to conform generally to an aortic arch of a human patient. A plurality of elongate woven tubular extents extend vertically from a top wall portion at the apical region of the tubular main wall. These tubular extents are sutured to the first woven section to provide fluid communication between the tubular main wall and the tubular extents.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
169 words
An arched implantable textile prosthesis comprising: a first woven section comprising an elongate tubular main wall having a first and a second open end defining a fluid passageway therethrough and further defining a lateral wall portion, a top wall portion and a bottom wall portion extending longitudinally therebetween, the first woven section being heat-settably arched with a radius of curvature from about 150 mm to about 300 mm defining an apical region of the main tubular wall between the first and second open ends; and a plurality of elongate woven tubular extents extending vertically from the top wall portion at the apical portion of the tubular main wall and being sutured to the first woven section to provide fluid communication between the tubular main wall and the tubular extents; wherein the first woven section can be further arched to a radius of curvature of from about 20 mm to about 80 mm to conform generally to an aortic arch of a patient without kinking of the tubular main wall.
Claim 2
Dependent Claim
169 words
An arched implantable textile prosthesis comprising: a first woven section comprising an elongate tubular main wall having a first and a second open end defining a fluid passageway therethrough and further defining a lateral wall portion, a top wall portion and a bottom wall portion extending longitudinally therebetween, the first woven section being heat-settably arched with a radius of curvature from about 150 mm to about 300 mm defining an apical region of the main tubular wall between the first and second open ends; and a plurality of elongate woven tubular extents extending vertically from the top wall portion at the apical portion of the tubular main wall and being sutured to the first woven section to provide fluid communication between the tubular main wall and the tubular extents; wherein the first woven section can be further arched to a radius of curvature of from about 20 mm to about 80 mm to conform generally to an aortic arch of a patient without kinking of the tubular main wall.
