Abstract
An aneurysm clip (1) is provided with two arms (2, 3) which are resiliently pivotable towards each other and carry at their free end clamping bars (12, 13) which are resiliently clamped against each other by the spring force of the arms, with outwardly curved sections of the arms adjoining the clamping bars and jointly forming a receiving space (10) for a vessel (11). In order to improve the safety of the application and the possibility of varying the application of the aneurysm clip, the clamping bars protrude from the arms towards both sides and thereby project laterally on both sides over the width of the arms in the outwardly curved sections.
Claims24
Aneurysm clip comprising:
- two arms joined at one end by a spring, said arms being pivotable towards each other about a pivot axis and carrying at respective free ends thereof clamping bars which, in a rest position, are resiliently held against each other by a spring force exerted by said spring;
- outwardly curved sections of the arms which precede said free ends forming a space for receiving a vessel portion that is not to be clamped;
- the clamping bars protruding parallel to said pivot axis and laterally away in opposite directions from first and second opposite sides of each of the outwardly curved sections, and being curved to provide one of a convex and a concave shape adapted to clamp an aneurysm;
- the respective positions of said space and said clamping bars allowing a protuberance of a vessel to be clamped by said bars when said vessel portion is received in said space without being clamped.
