Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
130 words
A device for anchoring a filament to tissue or bone, comprising: an anchor member adapted to be embedded in bone, the anchor having at least one cavity therein and including first and second components; and a filament having at least one portion extending from the at least one cavity, the filament being held in the at least one cavity by interference fit between the first and second components, the filament being substantially non-movable in response to a tensional force less than a threshold force applied to any of the at least one portion, the filament being longitudinally movable in response to a tensional force greater than the threshold force applied to any of the at least one portion, wherein the filament has a breaking strength greater than the threshold force.
Claim 2
Independent Claim
130 words
A device for anchoring a filament to tissue or bone, comprising: an anchor member adapted to be embedded in bone, the anchor having at least one cavity therein and including first and second components; and a filament having at least one portion extending from the at least one cavity, the filament being held in the at least one cavity by interference fit between the first and second components, the filament being substantially non-movable in response to a tensional force less than a threshold force applied to any of the at least one portion, the filament being longitudinally movable in response to a tensional force greater than the threshold force applied to any of the at least one portion, wherein the filament has a breaking strength greater than the threshold force.
Claim 3
Dependent Claim
26 words
The device of claim 1 , wherein the filament is passed through the at least one cavity in the anchor member to form a loop segment.
Claim 4
Dependent Claim
26 words
The device of claim 1 , wherein the anchor member includes a frangible portion that is adapted to shear during deployment of the device into bone.
Claim 5
Dependent Claim
16 words
The device of claim 1 , wherein the at least one cavity includes opposed open ends.
Claim 6
Independent Claim
102 words
A device for anchoring a filament to tissue or bone, comprising: an anchor member adapted to be embedded in bone, the anchor having at least one cavity therein and including first and second components; and a filament being held in the at least one cavity by interference fit between the first and second components, the filament having at least one portion extending from the at least one cavity, the filament being compressed within the at least one cavity such that a threshold tension necessary to move the filament is substantially the same as or greater than a breaking strength of the filament.
Claim 7
Independent Claim
102 words
A device for anchoring a filament to tissue or bone, comprising: an anchor member adapted to be embedded in bone, the anchor having at least one cavity therein and including first and second components; and a filament being held in the at least one cavity by interference fit between the first and second components, the filament having at least one portion extending from the at least one cavity, the filament being compressed within the at least one cavity such that a threshold tension necessary to move the filament is substantially the same as or greater than a breaking strength of the filament.
Claim 8
Dependent Claim
