Abstract
A device for forming an end-to-side anastomosis of blood vessels includes a first body for engaging an end portion of a blood vessel, a second body having a saddle portion that may be placed partly over a wall of a side portion of a further blood vessel and having a central hole which communicates with the wall for stably engaging the side portion of the further blood vessel. The first and second body are engaged together and in the engaging portion there are provided piercing elements adapted to penetrate the external surface of the wall without penetrating the internal surface of the wall of the further blood vessel so as to avoid direct contact between the piercing elements and the blood inside the vessel.
