Abstract

A deployment device for a prosthesis includes a driving assembly, including a driving tube and a driving pin. The driving assembly can impact a driven assembly, which is further connected to the prosthesis. The driving assembly can impact the driven assembly multiple times, thereby driving the prosthesis further into a tissue.

Claims

1. A deployment device for repairing tissue, comprising:

a front delivery assembly including a driven assembly configured to hold a prosthesis;

a base assembly comprising a driving assembly that is configured to impact the driven assembly;

a trigger assembly for activating the driving assembly;

wherein the deployment device is configured such that the driving assembly is adapted to impact the driven assembly multiple times by engaging the trigger assembly multiple times; and

wherein subsequent impacts of the driving assembly with the driven assembly are configured to drive the prosthesis farther into the tissue.

2. The deployment device according to claim 1, wherein the driving assembly is powered by an impact spring.

3. The deployment device according to claim 2, wherein the impact spring is compressed and released using the trigger assembly.

4. The deployment device according to claim 1, wherein the driving assembly undergoes an impact cycle that includes an energy storage stage and a driving stage.

5. The deployment device according to claim 4, wherein driving assembly returns to a substantially similar position between impact cycles.

6. The deployment device according to claim 1, wherein the front delivery assembly includes a depth indicator that can be used to determine if the prosthesis has been fully implanted into the tissue.

7. A deployment device, comprising:

a front delivery assembly including a driven assembly configured to hold a prosthesis;

a base assembly comprising a driving assembly;

a trigger assembly for activating the driving assembly;

wherein the deployment device is operable in;

an initial state in which the driving assembly is at rest and the driving assembly and the driven assembly are spaced apart by a first distance;

an intermediate state in which the driving assembly is at rest and the driving assembly and the driven assembly are spaced apart by a second distance;

a final state in which the driving assembly is at rest and the driving assembly and the driven assembly are spaced apart by a third distance; and

wherein the third distance is greater than the second distance and wherein the second distance is greater than the first distance.

8. The deployment device according to claim 7, wherein the position of the driving assembly is approximately the same in the initial state, the intermediate state and a final state.

9. The deployment device according to claim 7, wherein the position of the driven assembly within the front delivery assembly is advanced from the initial state to the intermediate state.

10. The deployment device according to claim 9, wherein the position of the driven assembly within the front delivery assembly is advanced from the intermediate state to the final state.

11. The deployment device according to claim 7, wherein the driven assembly is impacted by the driving assembly in between the initial state and the intermediate state and wherein the driven assembly is impacted by the driving assembly in between the intermediate state and the final state.

12. The deployment device according to claim 7, wherein the front delivery assembly has a first rotational position in which the driven assembly is aligned with the driving assembly and a second rotational position in which the driven assembly is out of alignment with the driving assembly.

13. The deployment device according to claim 12, wherein the front delivery assembly can be placed in a locked out state and a ready to actuate state and wherein movement of the driving assembly is prevented when the front delivery assembly is in the locked out state and wherein movement of the driving assembly is allowed when the front delivery assembly is in the ready to actuate state.

14. A method of implanting a prosthesis into tissue using a deployment device, comprising:

actuating a driving assembly so that the driving assembly engages a driven assembly corresponding to the prosthesis;

observing a position of a depth indicator that is associated with a depth to which the prosthesis has been implanted within the tissue; and

actuating the driving assembly a second time if the position of the depth indicator is spaced apart from a predetermined depth position.

15. The method according to claim 14, wherein actuating the driving assembly includes engaging a trigger portion of the deployment device.

16. The method according to claim 14, using the depth indicator to retract the driven assembly after the driven assembly has been engaged by the driving assembly.

17. The method according to claim 14, wherein actuating the driving device a second time is followed by observing a second position of the depth indicator.

18. The method according to claim 17, wherein observing the second position of the depth indicator is followed by actuating the driving assembly a third time if the second position of the depth indicator is spaced apart from the predetermined depth position.

19. The method according to claim 14, further comprising retracting the driven assembly when the prosthesis has been fully implanted.

20. The method according to claim 19, wherein retracting the driven assembly is accomplished by retracting the depth indicator.
