First Claim
Patent Images
1. A method of connecting a biological duct to a prosthetic device comprising:
- providing a prosthesis having a first, open end and side walls depending therefrom;
resecting a biological duct to which said prosthesis is to be attached to define a free end of said duct;
selecting a segment of living tissue remote from said duct;
securing said duct to a first portion of said tissue at a point spaced from the free end of said duct;
securing a second portion of said tissue spaced from said first portion to said first end of said prosthesis so that said free end of said duct is disposed at least partially in said open end of said prosthesis, whereby said duct is indirectly coupled to said prosthesis and a passage defined through said duct is in flow communication with said prosthesis through said open end thereof.

Abstract
An anastomotic method for connecting a biological duct, such as the ureter, to a man-made device. The method involves connecting the duct to the prosthesis via an intermediate tissue so there is no direct connection between the ureter and the prosthesis. The method includes securing the resected duct to a remote living tissue, such as the peritoneum or omentum, and then securing that tissue to the prosthesis so that the duct drains into the prosthesis.
