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 anchor component; and

a delivery device, the delivery device including a handle, an elongate portion extending from the handle, the elongate portion including a leading end, a needle tube, and a scope assembly, a needle assembly extending through the needle tube and configured to be advanced from the leading end, and the connector extending through the needle assembly;

wherein the leading end includes a needle targeting structure configured to facilitate targeting the needle through tissue.

2. The system of claim 1, wherein a terminal end of the needle assembly has a start position within view of the scope assembly.

3. The system of claim 1, wherein the leading end is configured with a guide to constrain the needle assembly to exit the leading end in a generally perpendicular direction with respect to the elongate portion.

4. The system of claim 1, wherein the needle assembly has a start position in a path of the second anchor component.

5. The system of claim 1, wherein the needle has a beveled tip on another side of the needle assembly from that of an inside radius as it is ejected from the delivery device.

6. The system of claim 1, wherein the scope assembly is laterally offset from the needle tube.

7. The system of claim 6, wherein one or more of the scope assembly and needle assembly are configured to be laterally translated.

8. The system of claim 1, wherein the scope assembly is configured to be translated axially.

9. The system of claim 1, further comprising a cover, wherein the cover is positioned between the needle tube and scope assembly.

10. The system of claim 1, wherein a viewing space is provided distal to scope assembly within the elongate portion.

11. 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;

a delivery device, the delivery device including a handle, an elongate portion extending from the handle, the elongate portion including a leading end, a needle tube, and a scope assembly, a needle assembly extending through the needle tube and configured to be ejected from the leading end, and the connector extending through the needle assembly;

wherein the elongate portion includes connector manipulating element configured to facilitate presenting the connector to the second component for a robust connection.

12. The system of claim 11, further comprising a cutter assembly, the cutter assembly including a slot having a length of greater than 0.045 inches and includes one or more reflection surfaces.

13. The system of claim 12, wherein the slot is sized and shaped to receive the connector, wherein the connector is placed into engagement with the proximal anchor.

14. The system of claim 11, wherein a bore extending through the needle and the connector diameter are sized so that the connector is supported about its circumference when within the needle bore.

15. The system of claim 11, wherein a portion of the connector includes an over jacket.

16. The system of claim 13, wherein a connector indicating feature is added to the keyhole to identify the position of the connector.

17. The system of claim 11, further comprising a cutter assembly, the cutter assembly including a window.

18. The system of claim 17, wherein reflection surfaces are provided on the window.

19. The system of claim 11, further comprising a cutter assembly, the cutter assembly configured to move and stop prior to engaging a connector.

20. The system of claim 17, wherein the cutter assembly further includes a guide to center a connector.

21. The system of claim 11, further comprising a guide configured to displace the connector perpendicularly with respect to the elongate portion.

22. The system of claim 21, wherein the guide is sliding and spring biased.

23. The system of claim 21, wherein the guide embodies a looped wire.

24. The system of claim 21, wherein the guide embodies an elongate pusher including a recess for the connector.

25. The system of claim 11, further comprising a pusher including a spring configured to engage the second component.

26. The system of claim 11, further comprising a pusher including a recess sized to receive the second component.

27. The system of claim 11, further comprising a backstop against which the second component is advanced when it is being engaged with the connector.

28. The system of claim 11, further comprising a temporary restraint positioned to engage the second component and launch the second component from the delivery device.

29. The system of claim 11, further comprising a cutter including a cutter tail.

30. The system of claim 11, further comprising a cutter assembly configured to be advanced toward a leading end of a spring biased proximal anchor.

31. The system of claim 11, wherein the elongate portion includes an advancing tip arrangement.

32. The system of claim 11, further comprising a rotating cutter assembly.

33. The system of claim 11, wherein the proximal anchor includes locking structure which defines an angle which is non-perpendicular to a long dimension of the proximal anchor, and includes knurled surfaces.
