Vascular prosthesis for use in the treatment of arterial diseases

A vascular prosthesis (1) made of biocompatible material comprising at least one first portion (1′) that is tubular and resilient at least in longitudinal sense, wherein at least said tubular and resilient first portion (1′) has at least one reinforcement frame (2) shaped like a cuff-like covering, said reinforcement frame (2) being adapted to allow the execution of at least one suture line with separated stitches for the stable and durable anchoring of said prosthesis (1) to the vascular core (100) of interest, said reinforcement frame (2) defining, with the prosthesis portion from which the reinforcement frame departs, an interspace (7), the latter being delimited by the external surface of the prosthesis portion enclosed by said reinforcement frame (2) and by the internal surface of the latter, said reinforcement frame (2) having a first base and a second base, said first base being that closest, with respect to said second base, to the vascular core (100) end to which said frame (2) is to be sutured and to the tubular portion of the prosthesis 1′ with which the frame is in a continuity relationship.
