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: 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.

Abstract: An incapacitating composition, for example of the type containing at least one incapacitating active ingredient is described, characterised in that it contains, as the active ingredient, a synergistic mixture of a piperidide, such as the piperine extracted from certain peppers, and of capsaicinoids extracted from certain capsicums. The composition is in the form of a solution, or combined with a powder, optionally diluted in an immiscible diluent The composition spraying device comprises an aerosol or a spray lance for the solution or the powder, or pyrotechnic or smoke-producing systems, weapons using ammunition comprising capsules of the powder or liquid containing the incapacitating composition, which ammunition is intended to be fired and to explode on the target or in the space surrounding the target.
