## Abstract

An assembly used in osteosynthesis comprising a delivery instrument in combination with an implant wherein the delivery instrument releasably holds the implant in a first configuration prior to attachment of the implant to bone. The delivery instrument allows the implant to be affixed to bone before the implant is released from the instrument. And the instrument may comprise guide means for drills, depth gauges, screws, pins, pegs, blades and or drivers which are used or implanted when the implant is releasably attached to the instrument. After the implant is affixed to bone and released from the delivery instrument, the implant assumes at least a second configuration which provides compression and or distraction and or control of spatial orientation.

## Claims

### Claim 1

A tissue fixation system comprising:
an implant, wherein the implant is movable between a first configuration and a second configuration; and
an inserter connectable to the implant;
wherein when the inserter is connected to the implant, the inserter is actuatable to move the implant between the first and second configurations, and the implant is fully seatable in a final position against a tissue;
wherein when the implant is fully seated in the final position against the tissue and the inserter is disconnected from the implant, the implant applies force to the tissue in at least a first direction.

### Claim 2 (depends on 1)

The tissue fixation system of claim 1, wherein the implant comprises a bridge comprising a tissue facing surface;
wherein when the inserter is connected to the implant, the entire inserter is on the same side of the tissue facing surface as the bridge.

### Claim 3 (depends on 2)

The tissue fixation system of claim 2, wherein the bridge comprises an upper surface, a first inserter engaging surface, and a second inserter engaging surface, wherein the tissue facing surface and the first and second inserter engaging surfaces face away from the upper surface, wherein the first and second inserter engaging surfaces are spaced apart from the tissue facing surface in a direction toward the upper surface;
wherein the inserter comprises an implant facing surface, a first implant engaging surface, and a second implant engaging surface, wherein the first and second implant engaging surfaces face toward the implant facing surface;
wherein when the inserter is connected to the implant, the upper surface faces the implant facing surface, the first inserter engaging surface engages the first implant engaging surface, and the second inserter engaging surface engages the second implant engaging surface.

### Claim 4 (depends on 2)

The tissue fixation system of claim 2, wherein when the inserter is actuated to move the implant toward the first configuration, the inserter bends the bridge.

### Claim 5 (depends on 4)

The tissue fixation system of claim 4, wherein the bridge extends between a first end and a second end, wherein the inserter supports the first and second ends and pushes on the bridge between the first and second ends.

### Claim 6 (depends on 1)

The tissue fixation system of claim 1, wherein the inserter comprises an implant configuration indicator.

### Claim 7 (depends on 1)

The tissue fixation system of claim 1, wherein the inserter comprises an interlock mechanism to keep the inserter connected to the implant when the implant is in an elastically deformed state.

### Claim 8

A tissue fixation system comprising:
an implant comprising an inserter attaching means, wherein the implant is movable between a first configuration and a second configuration; and
an inserter comprising an implant attaching means, wherein the implant attaching means engages the inserter attaching means so as to hold the implant in the first configuration and so as not to prohibit final seating of the implant in a final position against a tissue;
wherein when the implant is finally seated in the final position against the tissue and the inserter is disengaged from the implant, the implant moves toward the second configuration and applies force to the tissue in at least a first direction.

### Claim 9 (depends on 8)

The tissue fixation system of claim 8, comprising a tissue engaging member coupled to the implant.

### Claim 10 (depends on 9)

The tissue fixation system of claim 9, wherein the tissue engaging member is selected from the group consisting of a screw and a peg.

### Claim 11 (depends on 8)

The tissue fixation system of claim 8, wherein the implant comprises a tissue facing surface and an opposite top surface, wherein the inserter attaching means comprises a lower surface, wherein the tissue facing surface and the lower surface face away from the top surface, wherein the lower surface is spaced apart from the tissue facing surface toward the top surface.

### Claim 12 (depends on 8)

The tissue fixation system of claim 8, wherein the implant attaching means comprises a first member and a second member separated from the first member by a space.

### Claim 13 (depends on 12)

The tissue fixation system of claim 12, wherein the inserter is disengaged from the implant by changing the space between the first and second members.

### Claim 14 (depends on 12)

The tissue fixation system of claim 12, wherein the implant comprises a tissue facing surface, wherein the inserter attaching means comprises a first lower surface and a second lower surface, wherein the first and second lower surfaces are recessed from the tissue facing surface.

### Claim 15

A tissue fixation system comprising:
an implant comprising a tissue facing surface, a first lower surface, and a second lower surface, wherein the first and second lower surfaces are recessed from the tissue facing surface, wherein the implant is movable between a first configuration and a second configuration; and
an inserter comprising a first arm comprising a first upper surface and a second arm comprising a second upper surface, wherein a variable space exists between the first and second arms;
wherein when the inserter engages the implant, the first upper surface engages the first lower surface and the second upper surface engages the second lower surface to hold the implant in the first configuration and to permit the implant to be fully seated in a final position against a tissue;
wherein when the implant is fully seated in the final position against the tissue and the inserter is disconnected from the implant, the implant applies force to the tissue in at least a first direction.

### Claim 16 (depends on 15)

The tissue fixation system of claim 15, wherein the inserter is engaged to the implant and disengaged from the implant by varying the space between the first and second arms.

### Claim 17 (depends on 15)

The tissue fixation system of claim 15, wherein the implant comprises a top surface opposite the tissue facing surface, wherein the inserter comprises an implant contacting surface between the first and second arms, wherein when the inserter engages the implant, the implant contacting surface contacts the top surface to hold the implant in the first configuration.

### Claim 18 (depends on 17)

The tissue fixation system of claim 17, wherein the inserter engages the implant in the second configuration, wherein the implant contacting surface contacts the top surface to move the implant toward the first configuration.

### Claim 19 (depends on 15)

The tissue fixation system of claim 15, wherein the inserter comprises an interlock component to prevent the implant from being disengaged from the inserter when the implant is in the first configuration.

### Claim 20 (depends on 19)

The tissue fixation system of claim 19, wherein the implant in the first configuration is in an elastically deformed state with significant potential energy.
