Abstract
Abstract A surgical closure device having two mating members is disclosed. The first member comprises a plurality of pins, an indentation ajacent the proximal end of each pin, and at least one synthetic tissue compatible first fiber connecting the distal end of each adjacent pin. The second member comprises at least one synthetic tissue compatible second fiber having a plurality of knots essentially equal in number to the plurality of pins. A method of closing a wound of living tissue using the surgical closure device is also disclosed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
102 words
A surgical closure device having two mating members, the first member comprising a plurality of pins, an indentation adjacent the proximal end of each pin, and at least one synthetic tissue compatible first fiber, said fiber connecting the distal end of each adjacent pin, and the second member comprising at least one synthetic tissue compatible second fiber having a plurality of knots essentially equal in number to said plurality of pins, the inside diameter of each knot being essentially equal to or slightly less than the diameter of each pin, whereby each knot is capable of being held by a separate indentation.
Claim 2
Dependent Claim
102 words
A surgical closure device having two mating members, the first member comprising a plurality of pins, an indentation adjacent the proximal end of each pin, and at least one synthetic tissue compatible first fiber, said fiber connecting the distal end of each adjacent pin, and the second member comprising at least one synthetic tissue compatible second fiber having a plurality of knots essentially equal in number to said plurality of pins, the inside diameter of each knot being essentially equal to or slightly less than the diameter of each pin, whereby each knot is capable of being held by a separate indentation.
