Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
121 words
A clamp device adapted for occluding flexible tubular conduits comprising (1) a hook-shaped first jaw member with a concave inner surface, which jaw member is attached to an extended shaft, said first jaw member together with said shaft forming the shape of a J; (2) a second jaw member with a resiliently deformable convex inner surface, which jaw member is attached to an extended shaft, wherein said extended shafts are coextensively and slidably connected for moving and guiding said jaw members to maintain the concave and convex inner surfaces of said jaw members in an oppositely disposed and longitudinally engageable contacting relationship; and (3) biasing means for urging said jaw members into concave and convex inner surface contacting and conforming proximity.
Claim 2
Dependent Claim
121 words
A clamp device adapted for occluding flexible tubular conduits comprising (1) a hook-shaped first jaw member with a concave inner surface, which jaw member is attached to an extended shaft, said first jaw member together with said shaft forming the shape of a J; (2) a second jaw member with a resiliently deformable convex inner surface, which jaw member is attached to an extended shaft, wherein said extended shafts are coextensively and slidably connected for moving and guiding said jaw members to maintain the concave and convex inner surfaces of said jaw members in an oppositely disposed and longitudinally engageable contacting relationship; and (3) biasing means for urging said jaw members into concave and convex inner surface contacting and conforming proximity.
Claim 3
Dependent Claim
21 words
