Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
79 words
A surgical connector comprising: a) a grid plate having multiple holes therethrough, and distributed over the plate area, b) there being plate material in the form of a ring extending about each hole, c) the plate defining multiple arcuate ribs, d) three and only three of said ribs connecting each ring with three others of said rings, respectively, wherein at least two adjacent rings define a plane and are connected by an arcuate rib projecting upwardly of said plane.
Claim 2
Dependent Claim
79 words
A surgical connector comprising: a) a grid plate having multiple holes therethrough, and distributed over the plate area, b) there being plate material in the form of a ring extending about each hole, c) the plate defining multiple arcuate ribs, d) three and only three of said ribs connecting each ring with three others of said rings, respectively, wherein at least two adjacent rings define a plane and are connected by an arcuate rib projecting upwardly of said plane.
Claim 3
Dependent Claim
13 words
