Abstract: A device useful for implantation at a native heart valve can include an anchor element having a tubular configuration defining a longitudinal direction and a circumference, a heart valve prosthesis disposed within the anchor element, and a plurality of elongate members positioned at equidistant angular intervals about the circumference of the anchor element. The device can be configured to be transitioned from a radially collapsed delivery configuration to a radially expanded implantation configuration, and the plurality of elongate members can have a length extending in the longitudinal direction of the tubular member in the expanded implantation configuration.

Abstract: The implant implantation unit (2), at a determined position in the tubular element (51) with a wall comprising a cavity (50), is pushed there by a catheter (60) and the unit comprises deformable feelers (31) to, under the control of remote activation elements (42), change from a stowed form to a deployed functional form, to detect the cavity (50) and position itself there with reference to the position of the cavity.

Abstract: Embodiments of the present invention are directed to medical implants/stents, systems, and methods of treatment using such stents. Some embodiments of the invention include a self-expanding stent having a tubular first wall structure of a first diameter, where each end portion of the first wall structure is formed into a second wall structure of a second diameter larger than the first diameter. A membrane covers at least the first wall structure and the stent includes an interlaced, helicoidally wound wire forming a mesh-like structure.

Abstract: The device includes a solid disk (1) whose diameter is larger than the diameter of a hole (2) to be treated and which is formed by a peripheral deformable thread (6) made of a shape memory material and a flexible membrane (6) which is made of biocompatible material and connected to the thread; and at least an attachment (15) separated from the disk (1) which makes it possible to fix the disk (1) to the body wall. Each attachment (15) is provided with an area (16) for linking to the disk and an area (16) for linking to the body wall (3) and is embodied such that it is deformable and can be introduced into a hollow needle (28).

Abstract: This process comprises the step consisting in forming the structure from a single wire, by running each strand of wire helicoidally from one end to the other of the structure and by interlacing this strand with other strands previously arranged. Said method moreover comprises the steps consisting in:—forming a loop (12) between each strand (11b, 11c) at each end of the structure (10) and setting the free ends of the first (11b) and of the last strand significantly back from the ends of the structure (10).
