Abstract
Abstract A method for anastomosing an anatomical tubular structure that has an unhealthy section interposed between two healthy sections includes the steps of moving a tubular wall of the unhealthy section radially outwardly relative to a central axis and connecting the tubular walls of the two healthy sections together to form a junction. The unhealthy section of the anatomical tubular structure forms a toroid that is disposed about the junction. The anastomosis method can be performed without first cutting or removing the unhealthy section of any human or animal anatomical tubular structure. An anastomosis apparatus for anastomosing an anatomical tubular structure includes a first body member, a second body member and a connector device. Each body member has a hole formed therethrough with a diameter sized to receive the anatomical tubular structure in a close-fitting relationship and a slit that extends from the hole exteriorly of the body member. Each body member moves between a closed state wherein the body member circumscribes the anatomical tubular structure and an opened state wherein the body member separates at the slit a distance sufficient to receive the anatomical tubular structure. The connector device connects the first and second body members together after the anatomical tubular structure is received by the holes of the body members.

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
90 words
A method for anastomosing an anatomical tubular structure extending along a central axis and defined by a tubular wall, the anatomical tubular structure having an unhealthy section interposed between two healthy sections, the method comprising the steps of: moving the tubular wall of the unhealthy section radially outwardly relative to the central axis; and connecting the tubular walls of the two healthy sections of the anatomical tubular structure together to form a junction whereby the unhealthy section of the anatomical tubular structure substantially defines a toroid disposed about the junction.
Claim 2
Independent Claim
90 words
A method for anastomosing an anatomical tubular structure extending along a central axis and defined by a tubular wall, the anatomical tubular structure having an unhealthy section interposed between two healthy sections, the method comprising the steps of: moving the tubular wall of the unhealthy section radially outwardly relative to the central axis; and connecting the tubular walls of the two healthy sections of the anatomical tubular structure together to form a junction whereby the unhealthy section of the anatomical tubular structure substantially defines a toroid disposed about the junction.
