Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
177 words
A hemostat comprising a housing defined by at least two wall portions and having an open end situated at an edge of said wall portions, one of said wall portions extending beyond said open end continuing as a curl over and in spaced relation to said open end and terminating in a reverted lip that extends toward said edge to form a channel, said reverted lip being spaced from said edge to define a slot therebetween thereby to enable insertion of a blood vessel into said channel through said slot, said channel being curved in the longitudinal direction to present a convex surface to said open end and being curved in the transverse direction to present a concave surface to said open end, a resilient inflatable bladder carried by said housing with a part thereof situated at said open end and spaced from said channel, said part and said channel cooperating as a clamp when said bladder is inflated; and means communicating said bladder with a source of fluid pressure to control the inflation of said bladder.
Claim 2
Dependent Claim
177 words
A hemostat comprising a housing defined by at least two wall portions and having an open end situated at an edge of said wall portions, one of said wall portions extending beyond said open end continuing as a curl over and in spaced relation to said open end and terminating in a reverted lip that extends toward said edge to form a channel, said reverted lip being spaced from said edge to define a slot therebetween thereby to enable insertion of a blood vessel into said channel through said slot, said channel being curved in the longitudinal direction to present a convex surface to said open end and being curved in the transverse direction to present a concave surface to said open end, a resilient inflatable bladder carried by said housing with a part thereof situated at said open end and spaced from said channel, said part and said channel cooperating as a clamp when said bladder is inflated; and means communicating said bladder with a source of fluid pressure to control the inflation of said bladder.
Claim 3
Dependent Claim
33 words
The hemostat defined by claim 1 wherein said channel is formed with a transverse ridge disposed within said channel and intermediate the ends thereof, said ridge protruding toward said part of said bladder.
