A prosthesis (1) for a blood vessel (2) comprises an implantable tubular cylindrical element (3) of biocompatible material, affording a pair of rigid rings (5) positioned one at either end, that can be inserted into a diseased section of the opened vessel (2) with the rings offered in direct contact to corresponding healthy cylindrical portions (2c), also, a pair of first spiral wound locating elements (6) respectively associated with and encircling the rings (5) through a circumferential distance of no less than 360°, each of which is ensheathed freely in its turn by a second spiral wound stitching element (7) having a sharp point (7a); the second spiral wound element (7) is rotated helically about the first spiral wound element (6) and caused thus to advance along its own longitudinal axis (X), with the result that the rigid ring (5) becomes securely anchored as the point (7a) penetrates the wall of the vessel, progressively pinning the cylindrical portion (2c) to a given depth (S) between the two spiral wound elements (6, 7).

Une prothèse (1) pour vaisseau sanguin (2) comporte un élément cylindrique tubulaire implantable (3) en matériau biocompatible, présentant deux bagues rigides (5) dont une est placée à l'une des ses extrémités et peut être insérée dans une région malade du vaisseau ouvert (2), et lesdites bagues étant en contact direct avec les parties cylindriques saines correspondantes (2c). Cette prothèse comprend également une paire de premiers éléments en spirale (6) associés respectivement aux bagues (5) et les entourant sur une distance circonférencielle non inférieure à 360 DEG , lesdits éléments étant entourés, de manière lâche, d'un second élément de couture en spirale (7) présentant une pointe effilée (7a); le second élément en spirale (7) tourne en hélice autour du premier élément en spirale (6) et avance le long de son propre axe longitudinal (X), de sorte que la bague rigide (5) s'ancre fermement à mesure que la pointe (7a) pénètre dans la paroi du vaisseau et que la partie cylindrique (2c) soit attachée progressivement à une profondeur donnée (S) entre les deux éléments en spirale (6, 7).
