An anastomotic device, particularly a positioning device ( 24 ) extending along a longitudinal axis ( 30 ) comprises a first component, or proximal component ( 26 ) and a second component, or distal component ( 28 ). The proximal and distal components are suitable to lock an elastic ring ( 52 ) in a deformed configuration therebetween. The proximal component ( 26 ) has a substantially cylindrical outer structure with a cavity ( 32 ) for receiving a proximal end ( 52 a) of the elastic ring ( 52 ). The distal component ( 28 ) comprises a head ( 42 ) and a stem ( 44 ) developing along the longitudinal axis ( 30 ). The head ( 42 ) has a cone or truncated-cone shape. |
