ANASTOMOSIS DEVICE
First Claim
1. An anastomotic surgical stapling device comprising:
- an operator control assembly;
a tubular shaft longitudinally extending from the operator control assembly to a distal end; and
an actuating head portion at the distal end of said tubular shaft, said actuating head portion comprising(i) a detachable anvil portion with an axially extending stem portion and(ii) a stapling portion comprising a stapling mechanism for firing an array of staples around said stem portion and against said detachable anvil portion, wherein said anvil portion and said stapling portion matingly engage along a mating edge defined by locations around said stem portion spaced from a particular position on the axis of said stem portion by axially and/or radially varying distances.

Abstract
The present invention is directed to a circular anastomosis surgical stapler and methods of use. The circular anastomosis surgical stapler includes an operator control assembly, a tubular shaft having a distal end that is associated with a head portion, and an actuating head portion. The actuating head portion includes a detachable anvil portion with an axially extending stem portion. The anvil portion is engagable with the remainder of the head portion, which receives an array of staples. The head portion also includes an associated stapling portion with a stapling mechanism for firing an array of staples against the anvil portion. The anvil portion and the head portion matingly engage along a mating edge. The mating edge is defined by locations around the stem portion spaced from a particular position on the axis of the stem portion at axially and/or radially varying distances.
