Abstract

A blood vessel clip applicator includes two twist pins at one end, between which a blood vessel is placed before occlusion. A magazine in the blood vessel clip applicator holds a plurality of blood vessel clips and can be rotated independently from a grip assembly, whereby the twist pins can be rotated to compress a blood vessel held between them. The blood vessel clip is placed on the blood vessel after it has been flattened. The blood vessel clip includes spring quality material, and has a head connected to a first leg and a second leg. The magazine has a constricted region adjacent to an exit aperture. As the head enters the constricted region, the compressive force exerted on the head by the constricted region opens the blood vessel clip to an open position.

Claims

1. A blood vessel clip made of a spring-quality material, comprising:

a left head section;

a right head section forming a single loop configuration with the left head section;

a left leg section comprising a distal section and a proximal section, the proximal section of the left leg section being connected to the left head section; and

a right leg section comprising a distal section and a proximal section, the proximal section of the right leg section being connected to the right head section;

wherein the proximal section of the left leg section crosses the proximal section of the right leg section at a cross point of the left head section and right head section, the cross point disposed on the single loop configuration such that,

when a user applies a force to the right head section and another force to the left head section, the distal section of the left leg section is oriented away from the distal section of the right leg section so as to define a space for receiving a blood vessel, and,

when the user releases the force to the right head section or the another force to the left head section, a spring-like property of the spring-like material causes the distal section of the left leg section and the distal section of the right leg section to be oriented so as to close the space adapted to receive the blood vessel, thereby restricting the blood vessel;

wherein a left curled section of the left leg crosses a right curled section of the right leg section when the user releases the force to the right head section or the another force to the left head section.

2. The blood vessel clip of claim 1, wherein the distal section of the left leg section comprises the left curled section, the distal section of the right leg section comprises the right curled section, and the left curled section of the left leg section and the right curled section of the right leg section point substantially into the space adapted to receive the blood vessel when the user applies the force to the right head section and the another force to the left head section.

3. The blood vessel clip of claim 1, wherein said spring-quality material is stainless steel.

4. The blood vessel clip of claim 1, wherein said spring-quality material is titanium.
