<p>For connecting the end of a first blood vessel (6) to the side of a second blood vessel, which preferably has a greater diameter than the first blood vessel, use is made of a sleeve (11, 11') whose one end portion (12, 12') is expandable for the forming of an annular end flange (15, 15'). As a result, the first blood vessel (6), after being passed through the sleeve (11, 11') in the direction of the expandable end portion and folding back at least over the expandable end portion, is formable into a collar, both sides of which enclose the annular end flange inside the second blood vessel and internally surround an opening formed therein.</p> |
