Abstract

A single trigger 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 including an anchor assembly for assembly within a patient'"'"'s body, comprising;

a first anchor member;

a second anchor member including a first part and a second part;

a connector joining the first and second anchor members;

wherein one or both of the first and second parts are configured to be joined with the connector and each other within a patient'"'"'s body;

wherein the system is configured with a single trigger which accomplishes the assembly of the anchor assembly within a patient'"'"'s body and accomplishes the implantation of an assembled anchor assembly;

wherein the system is configured to deploy a plurality of anchor assemblies.

3. :

The system of claim 1, further comprising a needle assembly, wherein the system includes structure to extend the needle assembly to varying depths.

4. :

The system of claim 1, further comprising a mechanism to prevent incomplete activation of the trigger.

5. :

The system of claim 1, further comprising a scope wherein the scope extends substantially toward a terminal end of the anchor delivery device and provides a complete or partial view of deployment and assembly of same or all of the anchor assemblies.

7. :

The system of claim 1, further comprising a needle assembly, the needle assembly configured to house the first anchor member and connector, the needle assembly being operatively associated with the trigger.

8. :

The system of claim 7, further comprising a first pusher assembly, the first pusher assembly being operatively associated with the trigger and being placed into engagement with the first anchor member and connector.

9. :

The system of claim 8, further comprising a relative movement assembly operatively associated with the trigger, wherein actuation of a first actuator accomplishes the relative movement between the pusher assembly and the needle assembly.

10. :

The system of claim 9, further comprising a second pusher assembly, the second pusher assembly being operatively associated with the trigger and being placed into engagement with one part of the second anchor assembly.

11. :

The system of claim 10, further comprising a tension mechanism that is configured to apply approximately one pound of force on the connector.

12. :

The system of claim 10, wherein the tension mechanism is configured to apply approximately one half to five pounds force on the connector.

13. :

The system of claim 10, wherein the tension mechanism is configured to apply a selectable tension between approximately a half pound to five pounds of force on the connector.

14. :

The system of claim 1, wherein the anchor delivery device includes a penetrating member which is extendable from the system.

15. :

The system of claim 14, wherein the first anchor member is delivered through the penetrating member.

16. :

The system of claim 15, wherein the first anchor member and connector are pushed through the penetrating member by a rotary drive mechanism.

17. :

The system of claim 15, wherein the second anchor member is delivered without employing the penetrating member.

18. :

The system of claim 15, wherein the penetrating member is operatively associated with a tensile load system to thereby produce a load on the first anchor member when the penetrating member is retracted.

19. :

The system of claim 18, wherein the tensile load system is a rotary mechanism.

2. (canceled)

6. (canceled)

20. :

A system, comprising;

a plurality of multi-part anchor assembly assemblies; and

an anchor delivery device, the anchor delivery device including a single trigger;

wherein the multi-part anchor assembly is assemblies are delivered through the actuation of the single trigger.

21. :

The system of claim 20, wherein the anchor delivery device is loaded with the plurality of anchor assemblies and actuation of the single trigger accomplishes the delivery of the plurality of anchor assemblies.

22. :

The system of claim 20, wherein the anchor delivery device further includes a needle assembly, wherein a first trigger pull advances the needle assembly distally.

23. :

The system of claim 22, wherein a second trigger pull deploys a first component of an anchor assembly.

24. :

The system of claim 23, wherein a third trigger pull withdraws the needle assembly.

25. :

The system of claim 23, wherein a third trigger pull withdraws the needle assembly and applies a pulling force on the first component.

26. :

The system of claim 24, wherein a fourth trigger pull assembles and deploys a second component of the anchor assembly.

27. :

A method involving an anchor delivery device including a trigger assembly, a sub-assembly converting rotational motion into linear motion, and an interconnection assembly between the trigger assembly and the sub-assembly, comprising;

actuating the trigger assembly to cause a displacement of the interconnection assembly;

facilitating components of the sub-assembly to rotate in response to the displacement of the interconnecting assembly; and

permitting the sub-assembly to convert rotation of the components of the sub-assembly into linear motion of a portion of the sub-assembly.

28. :

The method of claim 27, wherein the trigger assembly includes a rack including teeth which engage a gear attached to a cam assembly, comprising causing the rack to move in a linear fashion to thereby rotate the gear and cam assembly.

29. :

The method of claim 28, wherein the interconnection assembly includes a rocker pawl configured to engage the cam assembly, comprising rotating the cam assembly to cause the rocker pawl to rotate away from a locking engagement with the sub-assembly.

30. :

The method of claim 29, wherein the sub-assembly includes a spring assembly, comprising permitting the components of the spring assembly to rotate upon disengagement of the rocker pawl from the sub-assembly.

31. :

The method of claim 30, wherein the sub-assembly further includes a scotch yoke, comprising actuating the scotch yoke to convert rotational movement of the spring assembly into linear movement of a portion of the sub-assembly.

32. :

The method of claim 31, wherein the anchor delivery device includes a needle assembly operatively associated with the sub-assembly, comprising causing the needle assembly to be advanced in response to the linear movement of the sub-assembly.

33. :

The method of claim 32, wherein the needle assembly houses a plurality of anchor components.
