Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 119 words
A surgical connector comprising: a) grid plate having multiple openings therethrough, b) said plate having multiple nodes distributed over the plate area, c) the plate defining multiple curved ribs interconnecting said nodes, d) there being at least three curved ribs connected to each node, e) said openings defined between said ribs, said openings having elongate dumb bell configuration, with narrow intermediate zones and enlarged end zones, f) the plate forming elongated tabs located at different sides of the plate, each tab connected to multiple of said ribs, each tab having length exceeding the length of each said elongate dumb bell configuration, each tab having width throughout its length exceeding the widths of the ribs to which it is connected.
Claim 2
Dependent Claim 119 words
A surgical connector comprising: a) grid plate having multiple openings therethrough, b) said plate having multiple nodes distributed over the plate area, c) the plate defining multiple curved ribs interconnecting said nodes, d) there being at least three curved ribs connected to each node, e) said openings defined between said ribs, said openings having elongate dumb bell configuration, with narrow intermediate zones and enlarged end zones, f) the plate forming elongated tabs located at different sides of the plate, each tab connected to multiple of said ribs, each tab having length exceeding the length of each said elongate dumb bell configuration, each tab having width throughout its length exceeding the widths of the ribs to which it is connected.
Claim 3
Dependent Claim 17 words
The connector of claim 1 wherein there are four of said curved ribs connected to each node.
Claim 4
Dependent Claim 12 words
