Abstract
Abstract The present invention provides a synthetic vascular prosthesis which is formed by a first tube member and a second tube member. Both tube members have inner flow paths for blood. An end of the second tube member is connected with an outer surface of the first tube member, and the inner flow path of the second tube member is communicated with the inner flow path of the first tube member.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
154 words
A synthetic vascular prosthesis comprising: a first synthetic vascular tube member defining an inner path for blood flow; and a second synthetic tube member defining an inner path for blood flow, said second tube member being constructed separately from said first tube member, a circumference of one end of said second tube member being connected with a circumference of an opening formed on an outer surface of said first tube member, said circumference of said one end of said second tube member consisting of a side edge formed in a direction substantially perpendicular to an axis of said second tube member and a cut-out edge extending from said side edge in a direction inclined to both the axis of said second tube member and said side edge, said circumference of said opening of said first tube member having a substantially identical shape as said circumference of said one end of said second tube member.
Claim 2
Dependent Claim
154 words
A synthetic vascular prosthesis comprising: a first synthetic vascular tube member defining an inner path for blood flow; and a second synthetic tube member defining an inner path for blood flow, said second tube member being constructed separately from said first tube member, a circumference of one end of said second tube member being connected with a circumference of an opening formed on an outer surface of said first tube member, said circumference of said one end of said second tube member consisting of a side edge formed in a direction substantially perpendicular to an axis of said second tube member and a cut-out edge extending from said side edge in a direction inclined to both the axis of said second tube member and said side edge, said circumference of said opening of said first tube member having a substantially identical shape as said circumference of said one end of said second tube member.
Claim 3
Dependent Claim
72 words
The synthetic vascular prosthesis according to claim 1, wherein the circumference of the opening of the first tube member and the circumference of the one end of the second tube member are both bent outwardly and an inner face of the first tube member adjacent the opening of the first tube member is bonded to an inner face of the second tube member adjacent the one end of the second tube member.
