Abstract: 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.

Abstract: The present invention relates to a bending actuator (1) comprising a plastic base layer (2) and a shape memory element (3) made from shape memory material, which can be actively shortened in a direction of action of the shape memory, wherein the shape memory element (3) is arranged outside the base layer (2) and is mechanically connected to the base layer (2) so that a bending occurs in the bending actuator (1) because of a pull by a contraction (K) of the shape memory element (3) in a direction of action of the shape memory, wherein an intermediate layer (6) is arranged between the shape memory element (3) and the base layer (2) in order to improve the transmission of force between the base layer (2) and the shape memory element (3), to prolong the service life and to reduce the degree of bend of the bending actuator (1), wherein the elasticity module of said intermediate layer (6) is less than the elasticity module of the base layer (2).
