Abstract
Abstract Disclosed is a hemostatic clip formed into a horseshoe shape from material having a generally triangular cross-section. The mating edges of the clip contain a groove used to provide space for the walls of the vessel when the clip is applied. The groove is located approximately in the center of the mating surfaces, and its width is less than one third the width of the mating surfaces. Because the width is less than one third of the mating surfaces, the other two thirds of the mating surfaces are too wide to fit into the groove, should the clip be applied in a misaligned manner. A plurality of slots in the occlusive surface of the clip help to hold the clip in position on a vessel, once the clip has been clamped into place. After the slots have been placed into the clip, the clip is processed in a tumbling operation to remove any serrations around the slots or at any other place on the clip. Thus, no protrusions remain around the slots to puncture a vessel during ligation. The triangular shape of the clip allows the clip to better fit into the jaws of the applier.

Claim 1
Independent Claim
99 words
A hemostatic clip comprising: a pair of arms formed from a single elongated strip of deformable material, said arms being interconnected at one end and open at the other end and arranged in laterally spaced apart substantially parallel relation, each of said arms being substantially triangular in cross-section with a flat side facing inwardly and with the apex facing outwardly; a longitudinal groove formed along said flat side of said arms, said groove having a width less than one third the width of said flat side, and said groove being formed substantially in the center of said flat side.
Claim 2
Dependent Claim

Claim 7
Dependent Claim
115 words
A process for making a hemostatic clip comprising the steps of: (a) forming a pair of arms from a single elongated substantially triangular strip of deformable material, said arms being formed to interconnect at one end and to be open at the other end, formed to be arranged in laterally spaced apart substantially parallel relation, and formed having a flat side facing inwardly with the apex of said substantially triangular strip facing outwardly; (b) shaping a longitudinal groove along said flat side of said arms, said groove being shaped to a width less than one third the width of said flat side, and said groove being located substantially in the center of said flat side.
Claim 8
Dependent Claim
115 words
A process for making a hemostatic clip comprising the steps of: (a) forming a pair of arms from a single elongated substantially triangular strip of deformable material, said arms being formed to interconnect at one end and to be open at the other end, formed to be arranged in laterally spaced apart substantially parallel relation, and formed having a flat side facing inwardly with the apex of said substantially triangular strip facing outwardly; (b) shaping a longitudinal groove along said flat side of said arms, said groove being shaped to a width less than one third the width of said flat side, and said groove being located substantially in the center of said flat side.
Claim 9
Dependent Claim
