An elastic ring, defining an inner opening, an outer contour and an annular bearing surface between the inner opening and the outer contour. The ring is deformable between a rest position and an insertion position in which the inner opening has a diameter greater than its diameter in the rest position. The ring is also elastically biased towards the rest position. The ring includes at least three strands passing through the ring, each strand having a first end and a second end positioned on the outer contour, the inner contour of the opening being defined by a portion of each strand and having a pseudo-polygonal shape.

Elastic ring and associated treatment device for implanting in a conduit for circulation of a body fluid

The kit includes: a first implant () defining a window (), and a second implant () including a second tubular body () designed to be positioned in the window (). The second implant () includes a retaining member for retaining the second implant () relative to the first implant. The kit further includes a retaining ring () for retaining the second implant () attached on the first tubular body () in the window () and delimiting an insertion passage () for the second implant (). The retaining ring () is elastically deformable in the window () to allow a reversible increase of at least 20%, advantageously at least 30%, of the outer contour of the insertion passage ().

Treatment kit, treatment device, and associated method of production

A method for producing an aortic or mitral heart valve prosthesis and the resulting aortic or mitral heart valve. The method is characterized in that it essentially consists in producing the prosthesis by shaping a textile material. The invention is more particularly applicable in the field of medicine, in particular repair surgery, and especially in heart surgery, more particularly heart prostheses.
