For connecting the end of a first blood vessel (6) to the side of a second blood vessel, the latter of which preferably has a greater diameter than the first blood vessel, an expandable end portion (12, 12') for forming an annular end flange (15, 15') is provided on a sleeve (11, 11'). 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. |
