Clip for aneurism

Clip for an aneurism suitable for being implanted into tissue in which an aneurism has formed and carrying out a tight closure of the aneurism. The clip includes a pair of claw members (2a, 2 b) non-metallic material, the claw members provided with an articulated joining mechanism (3), which allows rotation of the pair of claw members around a pivot (4) which interlocks them. The clip can adopt at least one opening position (A) and one closure position (B). The clip has at least one spring element (6) at least partially housed in the clip which bends to arrange the clip in closure position which includes at least one flexible (7) and elastic element with a section with arced configuration (8), press-fitted with two opposing ends (9a, 9b) each one exerting pressure on a different claw member both in the opening and in the closure position.
