Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
133 words
An anastomosis clamp comprising: a. a first open ended clamping collar having a substantially constant diameter and a relatively thin wall, b. a second open ended clamping collar having a substantially constant diameter and a relatively thin wall, c. a relatively narrow cross bar formed on each of said collars adjacent one end thereof extending across the open area defined by the collar on a diameter thereof, said collars having opposite clamping edges on the collar ends opposite said cross bars, d. means carried axially of said collars by said cross bars for guiding and holding said clamping collars together in clamping engagement, and e. means for urging the opposed clamping edges of said clamping collars together in clamping engagement wherein the open spaces in collars permit flow axially through the clamping collars.
