<p>When performing an end-to-side anastomosis connecting the end (10) of a first vessel (9) to the edge region (12) around an opening in the side wall of a second vessel (11), an instrument (1) is used having a circumferential stapling anvil (3) secured to an anvil tube (2) accommodating the first vessel (9), the end of which is everted about the anvil (3) with the intima of the end region (10) facing the intima of the edge region (12), when the instrument (1) with the first vessel (9) in place has been inserted into the opening in the second vessel (11). Then, a clamping tube (5) is advanced towards the anvil (3), clamping the end (10) and edge region (12) together against the anvil (3). In the next step, a number of stapling plungers (6) carrying staples (7) are advanced towards the anvil (3), the latter having staple-bending surfaces (4), thus stapling the two vessels together in a manner not shown. Finally, the clamping tube (5) and the stapling plungers (6) are withdrawn, and the whole instrument removed from the anastomosis.</p> |
