Abstract
Abstract A cannulated bioabsorbable tack has annular ribs configured to enhance fixation to tissue, such as bone, and is particularly effective for attaching soft tissue to bone, such as ligaments or muscles in the shoulder. Apparatus and method for display the tack facilitate arthroscopic surgical procedures for attaching or joining tissue.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
128 words
An inserter for use in engaging tissue to be oriented adjacent bone at an attachment site comprising an elongate member having a proximal end, a distal end and a longitudinal passage therethrough; and barb means disposed at said distal end of said member for engaging tissue in barb-like fashion and having a longitudinal passage therethrough aligned with said passage through said member whereby a trocar wire can pass through said passages in said member and said barb means, said barb means including a neck extending from said distal end of said member and a frusto-conical tip extending from said neck having an open distal end and a proximal end having a diameter greater than a transverse dimension of said neck to define an edge for engaging the tissue.
Claim 2
Dependent Claim
128 words
An inserter for use in engaging tissue to be oriented adjacent bone at an attachment site comprising an elongate member having a proximal end, a distal end and a longitudinal passage therethrough; and barb means disposed at said distal end of said member for engaging tissue in barb-like fashion and having a longitudinal passage therethrough aligned with said passage through said member whereby a trocar wire can pass through said passages in said member and said barb means, said barb means including a neck extending from said distal end of said member and a frusto-conical tip extending from said neck having an open distal end and a proximal end having a diameter greater than a transverse dimension of said neck to define an edge for engaging the tissue.
Claim 3
Dependent Claim
28 words
An inserter as recited in claim 1 wherein said distal end of said member has a rounded shoulder to prevent said distal end from cutting through the tissue.
Claim 4
Dependent Claim
55 words
An inserter as recited in claim 1 and further comprising a trocar wire passing through said passages in said member and said barb means, said trocar wire including a sharp conical distal end extending from said open distal end of said tip and having an annular shape to be a smooth extension of said tip.
Claim 5
Dependent Claim
34 words
An inserter as recited in claim 3 and further comprising a handle removably secured to said proximal end of said member and wherein said trocar wire has a proximal end received in said handle.
Claim 6
Dependent Claim
166 words
An inserter for use in engaging tissue to be oriented adjacent bone at an attachment site comprising an elongate member having a proximal end, a distal end and a longitudinal passage therethrough; and barb means disposed at said distal end of said member for engaging tissue in barb-like fashion and having a longitudinal passage therethrough aligned with said passage through said member whereby a trocar wire can pass through said passages in said member and said barb means, said bar means including a neck extending from said distal end of said member and a tip extending from said neck, said tip having an open distal end and a proximal end with a transverse dimension larger than a corresponding transverse dimension of said neck to define an edge for engaging the tissue, said transverse dimension of said proximal end also being larger than a corresponding transverse dimension of said distal end of said tip such that said barb tapers from its proximal end to its distal end.
Claim 7
Dependent Claim
166 words
An inserter for use in engaging tissue to be oriented adjacent bone at an attachment site comprising an elongate member having a proximal end, a distal end and a longitudinal passage therethrough; and barb means disposed at said distal end of said member for engaging tissue in barb-like fashion and having a longitudinal passage therethrough aligned with said passage through said member whereby a trocar wire can pass through said passages in said member and said barb means, said bar means including a neck extending from said distal end of said member and a tip extending from said neck, said tip having an open distal end and a proximal end with a transverse dimension larger than a corresponding transverse dimension of said neck to define an edge for engaging the tissue, said transverse dimension of said proximal end also being larger than a corresponding transverse dimension of said distal end of said tip such that said barb tapers from its proximal end to its distal end.
Claim 8
Dependent Claim
50 words
An inserter as recited in claim 5 and further comprising a trocar wire passing through said passages in said member and said barb means, said trocar wire including a distal end tapering from said open distal end of said tip to comprise a smooth transition and extension of said tip.
Claim 9
Dependent Claim
34 words
An inserter as recited in claim 6 and further comprising a handle removably secured to said proximal end of said member, and wherein said trocar wire has a proximal end received in said handle.
