Abstract

An anastomosis is performed using a flexible mounting structure mounted on the outside of at least one vessel. Fasteners extend through the vessel and are bent towards the incision to attach the flexible mounting structure to the vessel in a manner that controls the edge of the vessel adjacent to the incision. The mounting structures are oriented on each vessel so fasteners on one mounting structure interdigitate with fasteners on the other mounting structure at the location of contact between the vessels when the two vessels are brought together. This creates two complementary sinusoidal-shaped vessel edges with peaks of one edge being accommodated in the valleys of the other edge. The peak-to-valley orientation forms a sinusoidal-shaped joint which is leak free. The fasteners are spaced so proper pressure is applied to the tissue to promote healing without leaking. Furthermore, the fasteners are sized and shaped to properly engage the tissue and bend in a desired manner. Methods and tools for carrying out the anastomosis according to the invention are also disclosed. Methods for forming the fastener and the tines having the proper characteristics are disclosed. An absorbable ring-shaped stent is also disclosed.

Claims4

Dependent claims

A method for forming an anastomosis comprising:

A) forming an incision in a first vessel;
B) installing an anvil into the first vessel through the incision;
C) mounting a first malleable mounting structure on the first vessel by setting fasteners on the first mounting structure into the first vessel adjacent to the incision;
D) fully forming the fasteners by driving them against the anvil and gently turning them toward the incision;
E) manipulating the first mounting structure into a configuration opening the incision in the first vessel;
F) removing the anvil from the first vessel through the incision therein;
G) forming an incision in a second vessel;
H) installing an anvil into the second vessel through the incision in the second vessel;
I) mounting a second malleable mounting structure on the second vessel by setting fasteners on the second mounting structure into the second vessel adjacent to the incision in the second vessel;
J) fully forming the fasteners of the second mounting structure by driving them against the anvil in the second vessel and gently turning them toward the incision in the second vessel;
K) manipulating the second mounting structure into a configuration opening the incision in the second vessel;
L) removing the anvil from the second vessel through the incision therein;
M) guiding the first and second mounting structures into contact with each other to bring the first and second vessels in abutting contact with each other;
and
N) connecting the first and second mounting structures together.
