Abstract

A system and associated method for manipulating tissues and anatomical or other structures in medical applications for the purpose of treating diseases or disorders or other purposes. In one aspect, the system includes a delivery device configured to deploy and implant anchor devices for such purposes.

Claims

1. A system for treatment of body tissue, comprising:

an anchor assembly, the anchor assembly including a first component and a second component; and

a delivery device, the delivery device including a needle assembly, a needle deploy actuator and a retract lever;

wherein the actuator accomplishes automated deployment of the needle assembly and the lever accomplishes manual withdrawal of the needle assembly;

wherein the delivery device includes a needle deployment spring and actuation of the actuator results in the needle deployment spring automatically advancing the needle assembly with a force sufficient to penetrate target tissue;

wherein actuation of the lever accomplishes manual retraction of the needle assembly without involvement of the deployment spring;

wherein the delivery device includes a spool assembly controlling the position of the needle assembly.

2. The system of claim 1, wherein the spool assembly includes the needle deployment spring.

3. The system of claim 2, wherein the delivery device includes a cartridge assembly, the cartridge assembly housing one anchor component.

4. The system of claim 3, wherein the cartridge assembly is replaceable.

5. The system of claim 4, wherein the cartridge assembly is configured to releasably engage the spool assembly.

6. The system of claim 5, wherein the cartridge assembly is configured to feed the one anchor component within the needle assembly.

7. The system of claim 6, wherein the cartridge assembly includes a spring.

8. The system of claim 7, wherein a clutch is provided to disassociate the cartridge assembly from at least a portion of the spool assembly.

9. The system of claim 8, wherein the spring is configured to apply a tension on the one anchor component.

10. The system of claim 9, wherein the delivery device includes a trigger assembly.

11. The system of claim 10, wherein the trigger assembly is configured to effect assembly of the anchor assembly.

12. The system of claim 11, wherein the trigger assembly controls severing of a third component of the anchor assembly.

13. The system of claim 12, wherein the delivery device includes a bail-out assembly configured to sever the third component of the anchor assembly.

14. The system of claim 13, wherein the delivery device includes a first reset lever configured to reset the needle spool assembly.

15. The system of claim 14, wherein the delivery device includes a second reset lever configured to reset the trigger assembly.

16. A system for treatment of body tissue, comprising:

an anchor assembly; and

a delivery device including a needle assembly, a spool assembly, a trigger assembly, a first actuator, a second actuator and a third actuator;

wherein actuation of the first actuator advances the needle assembly and a portion of the anchor assembly, actuation of the second actuator withdraws the needle assembly and actuation of the third actuator accomplishes assembly of the anchor assembly.

17. The system of claim 16, wherein the delivery device includes a first reset lever and a second reset lever, wherein the first reset lever resets the spool assembly and the second reset lever resets the trigger assembly.

18. The system of claim 17, wherein the delivery device includes a bail-out assembly and actuation of the bail-out assembly accomplishes severing a component of the anchor assembly.

19. The system of claim 16, wherein the delivery device includes a lock-out assembly which locks the lever until after depression of the first actuator.

20. The system of claim 16, wherein the delivery device includes a locking mechanism which locks the lever in a depressed condition.

21. The system of claim 16, wherein the delivery device includes a first actuator lock which prevents accidental needle deployment.

22. The system of claim 16, wherein the delivery device includes structure to avoid premature deployment of the third actuator until the second actuator is fully depressed.

23. The system of claim 16, wherein a needle moves along a curved trajectory within the needle assembly.
