Abstract

A hemostatic clip useful in the strangulation of tubular members and formed of elongate deformable material is disclosed. The clip consists of a pair of arms coupled at one end and open at the other, the arms being separated in a substantially opposed relationship and each having a flat surface facing inwardly. Located in the flat surfaces of the arms are diagonal recesses. The recesses in opposing surfaces are arranged so as to be angularly displaced with respect to one another such that when the surfaces are brought into contact the recesses on opposing surfaces form a cross-hatched pattern.

Claims

1. A hemostatic clip formed of elongate deformable material for use in the strangulation of tubular members by means of a hemostatic clip applicator, the clip applicator of the type having jaw portions adapted to receive and maintain hemostatic clips via grooves in said jaws, said jaws further having stop portions at the extremity thereof adapted to maintain said hemostatic clips within said grooves, the hemostatic clip being generally U-shaped and comprising:

(i) a bail portion forming the base of said U-shape;

(ii) a pair of arms extending from said bail portion and forming the extremities of said U-shape, said arms being separated in a substantially opposed relationship and having opposing substantially flat surfaces, each arm being substantially longer than said bail portion, whereby said substantial length of said arm portions results in stability of said clip in said clip applicator, each arm having a generally trapezoidal cross-section with a narrower outer portion adapted to be received in a respective groove of said clip applicator; and

(iii) a plurality of spaced parallel diagonally disposed grooves extending downwardly into each of said clip arm opposing surfaces, said grooves extending below each clip arm flat surface and being spaced apart sufficiently so that substantial portions of said flat surface remain between adjacent grooves, the grooves on one arm extending solely in one direction, the grooves on the other arm extending solely in an opposite direction such that the grooves in opposing surfaces are angularly displaced with respect to one another, whereby said grooves form a generally cross-hatched pattern when said opposing substantially flat surfaces are brought into facing contact with one another.

2. The clip of claim 1 wherein said bail portion is V-shaped and each arm is coupled to one extremity of said bail portion.
