Abstract: In a method for producing an implant from a biocompatible silicone, a 3D mathematical model of an implant to be produced is used to create a 3D model of a casting mold for the implant as a negative. The casting mold is produced from a polymeric material through an additive manufacturing process and coated through vapor deposition of a coating material from the parylene family at least in a region that comes into contact with the biocompatible silicone to be cast. A platinum-catalyzed 2-component thermosetting silicone as the biocompatible silicone for the implant is introduced into a mold cavity of the coated casting mold, with a residence time of the implant in a patient's body of more than 29 days. The casting mold is heated to vulcanize the biocompatible silicone, and after cooling down the vulcanized implant is demolded from the casting mold.

Abstract: An endoscopy device for introducing an expandable body into a cavity includes a first endoscope having a working channel, a further endoscope accommodating the expandable body and insertable with the expandable body in the working channel of the first endoscope, and a video unit located in the further endoscope in parallel relation to the expandable body and having a distal end situated next to a distal end of the expandable body in order to place the expandable body under visual control in the cavity prior to expansion. The video unit is designed to form an abutment at a proximal end of the expandable body after positioning of the expandable body and when the further endoscope is withdrawn.

Abstract: A stent has a center length section, two end sections, and an elastically deformable woven wire mesh, which enables the stent to expand from a small diameter to a larger diameter, with the diameter of the end sections being larger than in the center length section in the expanded state. The wire extends in a zig-zag manner from an outer end of one end section toward the outer end of the other end section, and back in a zig-zag manner to the one end section. The peripheral direction of the woven wire changes at the transition from an end section to the center length section, such that the wire intersects on the return path to the one end section in the center length section and overall forms an 8-shaped loop having two closed eyes, wherein a plurality of interconnected loops are arranged offset to each other over the circumference.

Abstract: A stent in the form of a generally tubular body has multiple annularly expandable serpentine elements. The serpentine elements have arcs at the first and second element ends which point in the axial direction of the stent. Annularly expandable serpentine elements which follow one another in the axial direction are connected to one another via connectors which are arranged at the ends of the adjacent elements. The connectors extend in the circumferential direction of the stent in the non-expanded state of the stent and have a curvature in the circumferential direction. In the expanded state of the stent, the curvature is so great in the circumferential direction that the connectors project radially outward beyond the circumference of the serpentine elements.

Abstract: According to the invention, the one-piece tubular body (2) of the endoprosthesis comprises a flexible intermediate part (21) permitting the relative orientation of the parts (2A, 2B) of said body (2) that are situated on either side of said flexible intermediate part (21).

Abstract: The bronchial plug (1) comprises a hollow body (2), the front side (4) of which is open and the back side (5) of which comprises at least one valve (6) being closed in the normal state thereof and adapted to be voluntarily or spontaneously opened so as to form a communication orifice. It further comprises gripping means (7) especially dedicated to a guide (10) adapted to position it in a bronchus (16), said gripping means (7) being arranged on the front side of said valve (6) and accessible through said valve (6).

Abstract: An endoprosthesis may be implanted in the region of an anatomical canal that is experiencing impairment. An exterior surface wall of the endoprosthesis bears projecting studs that cooperate with the wall of the anatomical canal so as to hold the endoprosthesis in position. One of the projecting studs is hollow and acts as a reservoir for a product that is active against the impairment.

Abstract: The present invention relates to a structure of a prosthesis intended to be implanted in a human or animal passage, particularly an artery, to provide through-passage along said passage, said structure (2) comprising at least one mesh (4) which, at least in part, is approximately cylindrical and comprises at least one corrugated filament (F) forming approximately annular units (UA) linked together, at least some of the corrugations (ON) of said corrugated filament (F) of two respective adjacent units (UA) being linked to one another by linking means (5). According to the invention, at least some of said linking means (5) comprise links (6A, 6C) which are made as a rigid piece and which are provided with at least two loops joined together and, in the case of each of said links (6A, 6C), each of the two loops of the link (6A, 6C) entraps, with some clearance, one of the two corrugations (ON) which are to be linked together.

Abstract: According to the invention, said prosthesis (I) comprises projecting studs (3) at least some of which form a reservoir able to contain an active product (5) that acts against an impairment of said anatomical canal.

Abstract: The present invention relates to a bifurcated aortic prosthesis comprising a structure (2) which comprises a main trunk (3) which divides into two branches (4, 5) of equal lengths and which has shape memory, and at least one impervious envelope (6) completely enveloping said branches (4, 5) and at least partially enveloping said trunk (3). According to the invention, said envelope (6) has a length (L) such that, in the position in which it is implanted in the aorta (AO), it approximately covers that part of the aorta (AO) which lies between the renal arteries (A1, A2) and the iliac arteries (A3, A4) and the length (l2) of said branches (4, 5) is between 1/4 and 2/5 of the length (L) of said envelope (6).

Abstract: Release of an object into a human or an animal passage is performed via a catheter formed of telescopic first and second sheaths. The catheter is at least partially inserted into the passage to release the object in response to relative sliding of the first and second sheaths. The catheter includes a first fixing device that fixes an extra-corporal part of the first sheath to a casing and a second fixing device that fixes an extra-corporal part of the second sheath to a mobile carriage mounted on the casing. A controllable motor moves the mobile carriage with respect to the casing.
