A device for forming an end-to-side anastomosis of blood vessels or ducts comprises first means (7) for engaging an end portion (2) of a blood vessel or of a prosthesis, second means (35) for stably engaging a side portion (4) of the blood vessel or prosthesis, and means (10, 14) for reciprocally connecting the first and second engagement means (7, 35). The second engagement means (35) comprise one or more piercing elements (9) adapted to only partially penetrate the side wall (4) of the blood vessel or prosthesis so as to avoid direct contact between the elements (9) and the blood inside the vessel or prosthesis. |
