Surgical clip
First Claim
1. A surgical clip for use with a mechanical clip applying device for occluding the flow of blood through a vein, artery or similar vessel, the clip having first and second opposed legs interconnected at a back end to form a bight portion and spaced at the opposite distal ends, the improvement comprising:
- longitudinal channel means on the inside surface of each of said opposed legs and extending substantially from the spaced distal end to the bight portion for preventing longitudinal slippage of said clip relative to the vessel after said clip has been deformed about the vessel, said longitudinal channel means defined by an open sided channel having a pair of spaced generally parallel side walls and a bottom surface, a plurality of lateral channel means extending across the inside surface of said first and second opposed legs and traversing said longitudinal channel means for preventing lateral slippage of said clip relative to the vessel after said clip has been deformed about the vessel, said lateral channel means being defined by a bottom wall generally parallel to the inside surface of said leg in which it is formed, and bight and distal walls extending between said bottom wall and said inside surface, said distal wall being generally planar and forming an acute angle with said bottom wall.

Abstract
The present invention relates to a surgical clip for occluding the flow of blood through a blood vessel, artery or vein. The clip formed with longitudinal and transverse or lateral notches to prevent both longitudinal and lateral slippage of the clip with respect to the vessel. The clip is also provided with coined front legs to assist in deformation about a vessel and to further provide a self aligning feature when the clips are arranged in an abutting, forward facing row. The apparatus of the present invention forms the foregoing described clip and does so in a symmetrical way to provide a clip with a uniform stock length.

- 5. A surgical clip for occluding the flow of a body fluid through a vein, artery or similar vessel for use with a mechanical clip applying device adapted to hold a plurality of the clips abuttingly arranged in a forward facing row and deform each successive clip to provide two generally parallel legs joined at a bight portion, the clip, prior to deformation, having proximal leg portions connected together at the bight portion and forming an angle therebetween, and distal leg portions, each distal leg portion being connected to its respective proximal leg portion at an obtuse angle, the distal and proximal leg portions being substantially coplanar and the distal leg portions being substantially parallel, the improvement comprising bevelled formations at the free ends of the distal leg portions disposed and arranged to cause each clip to have a clip stack length equal to the clip stack length of every other clip in the row of clips and to engage the proximal leg portions of the preceding clip in the row of clips to cause the row of clips to advance while maintaining linear alignment upon the application of a force to the last clip in the row of clips.
