Abstract
Abstract An improved hemostatic clip for use in occluding blood vessels during surgical procedures is disclosed which is formed of bio-absorbable magnesium and is shaped to minimize any effects of the brittle properties of magnesium during use. The metallic bio-absorbable clip is smaller in size than existing non-metallic, bio-absorbable clips and eliminates the need for a locking mechanism structure on the clip.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
97 words
A hemostatic clip for closing blood vessels, comprising: a body including a pair of elongate arm members extending in close spatially oriented, generally like direction from a central bight portion when in open position, said elongate arm members each having distal end portions and being plastically deformable adjacent said distal end portions for providing closure of said clip without substantial deformation of said bight portion thereof, said bight portion having a larger mass than said arms thereof for increased strength and less deformation upon closing, and said body being a metal structure made of nontoxic bio-absorbable material.

Dependent Claim
