Abstract
A device for forming an anastomosis of blood vessels or ducts comprises: first and second engagement structures (7, 10; 35) for respectively engaging a first end portion (2) of a blood vessel (1) or of a prosthesis and a second end or side portion (4, 4') of the blood vessel (1) or prosthesis; and a mechanism (14, 14') for reciprocally connecting the first and second engagement structures. The first engagement structure (7, 10) comprise one or more piercing elements (6) adapted to only partially penetrate the side wall of the blood vessel (1) so as to avoid direct contact between the elements (6) and the blood inside the vessel or prosthesis.
