摘要
The invention concerns a medical set designed to be implanted in an anatomical duct (10) comprising a prosthesis (1) insertible in a duct having an upstream zone relative to the circulation direction of a liquid flowing therein, the prosthesis comprising a structure adapted to take up a first radially constricted state, to be inserted into the duct, or a second radially unfolded state wherein the structure has the general shape of a single or bifurcated tube to be set substantially resting against the duct wall (10), and at least a ring (29) comprising a flexible strap (45, 48) and adapted to be located at least opposite the prosthesis proximal end (1a) at right angle with said duct upstream zone when the set is implanted therein. The invention is characterised in that the ring further comprises a reinforcing structure (33) extending over part at least of the length of the strap to which it is linked to make it rigid.
