The invention concerns a device comprising: an implant (1) with an elongated deformable structure, such that the implant can adopt an elongated shape to be inserted into the patient's body through a passage of reduced diameter and a curved shape adapted to perform annuloplasty; and a tubular instrument (2) for receiving at least partly said implant (1) therein, having a rigidity such that it enables the implant (1) to be inserted in the patient's body through said passage; said instrument (2) comprises an orifice (12, 13) at its distal end, providing access to the implant (1), means (15) for locking the implant (1) in rotation relative thereto, means (15) for maintaining the implant (1) relative thereto, and means for locating its angular orientation inside the patient's body. Said device is particularly designed for use in the reconstruction of cardiac valves.

Ce dispositif comprend: un implant (1) ayant une structure allongée et déformable, telle que l'implant peut prendre d'une part une forme allongée pour son introduction dans le corps du patient par un passage de diamètre réduit, et d'autre part une forme courbe adaptée à la réalisation de l'annuloplastie, et un instrument tubulaire (2) propre à recevoir au moins partiellement ledit implant (1) en lui, qui présente une rigidité telle qu'il permet l'introduction de l'implant (1) dans le corps du patient par ledit passage; cet instrument (2) comprend une ouverture (12, 13) au niveau de son extrémité distale, permettant l'accès à l'implant (1), des moyens (15) de calage en rotation de l'implant (1) par rapport à lui, des moyens (15) de maintien de l'implant (1) par rapport à lui, et des moyens de repérage de son orientation angulaire à l'intérieur du corps du patient. Notamment utilisable pour la reconstruction de valves cardiaques.
