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 attached to a connector and a second component; and

a delivery device, the delivery device including a needle assembly attached to a needle spool, a needle deploy actuator and a retract lever, a connector spool and a lever lock and tape;

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

wherein the lever lock and tape includes a body having a central axis coinciding with central turning axes of the needle spool and connector spool, the lever lock and tape configured to lock the lever and translate action of the lever to rotate the needle assembly.

2. The system of claim 1, wherein the delivery device includes a needle deployment spring and actuation of the needle deploy actuator results in the needle deployment spring turning the needle spool and the connector spool to automatically advance the needle assembly with a force to penetrate through and beyond a prostate and outer capsule of the prostate.

3. The system of claim 2, wherein the delivery device includes a pawl controlling the rotation of the connector spool relative to the needle spool.

4. The system of claim 3, further including a tension spring configured about the connector spool, the tension spring applying tension to the connector.

5. The system of claim 4, wherein the tension spring applies tension contemporaneously with independent rotation of the needle spool.

6. The system of claim 5, wherein a tape portion of the lever lock and tape is attached directly to the lever.

7. The system of claim 6, wherein the needle assembly houses a first component of the anchor assembly.

8. The system of claim 7, wherein the system includes a second component of the anchor assembly.

9. The system of claim 8, wherein a terminal end of the needle includes a bevel defining a radius approximating a profile of the connector.

10. The system of claim 9, wherein actuators of the lever retracts the needle assembly farther than the needle can be advanced.

11. The system of claim 10, wherein the delivery device includes a safety mechanism incorporated into the retract lever, the safety mechanism locking the needle deploy actuator.

12. The system of claim 11, further including an anchor assembly structure configured to effect assembly of the second component to the connector.

13. The system of claim 12, further including a cutter assembly for severing of the connector of the anchor assembly, the cutter including spacing structure for ensuring a tag remains after severing the connector.

14. The system of claim 13, wherein the cutter assembly includes structure for aligning the connector with the second component.

15. The system of claim 14, the delivery device further including a terminal end having one or more direction or position indicators.

16. The system of claim 15, further including an introducer sheath, wherein the delivery device includes a sheath mount including a seal.

17. The system of claim 16, further comprising a pusher assembly operatively associated with a third actuator, the pusher assembly including an extension for receiving the second component and for providing spacing to cut the connector.

18. The system of claim 17, wherein the cutter is operatively associated with the third actuator.

19. The system of claim 18, further comprising an interlock for locking the third actuator.

20. The system of claim 17, further comprising a spring for accomplishing longitudinal movement of the pusher and cutter.
