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 creating continuous defects or indentations in lobes of a prostate.

Claims

1. A method for creating a continuous indentation in a prostatic urethra, comprising:

inserting an anchor delivery device within a urethra;

actuating the anchor delivery device to implant first and second anchors on a first side of a lobe of a prostate and a third anchor on a second side of the lobe, the third anchor connected to both first and second anchors;

arranging the third anchor to form a continuous indentation in the second side of the lobe; and

removing the anchor delivery device from the urethra.

2. The method of claim 1, further comprising compressing the lobe of the prostate with the anchor delivery device.

3. The method of claim 1, further comprising deploying third and fourth anchors on the second side of the lobe.

4. The method of claim 1, further comprising connecting the third anchor to the first anchor.

5. The method of claim 4, further comprising connecting a fourth anchor to the second anchor.

6. The method of claim 1, further comprising actuating the anchor delivery device to extend at least two needles beyond a prostate capsule.

7. The method of claim 6, further comprising causing a first needle to be extended at an angle with respect to a second needle.

8. The method of claim 6, further comprising configuring the at least two needles so that they extend an equal length when extended.

9. The method of claim 6, further comprising configuring the at least two needles so that they extend different lengths when extended.

10. The method of claim 6, further comprising extending the at least two needles so that they cross paths when extended.

11. The method of claim 1, further comprising creating one or more permanent valleys along the prostatic urethra.

12. The method of claim 1, further comprising employing an introducer sheath to insert the delivery device within the urethra.

13. The method of claim 12, further comprising attaching an atraumatic tip to the introducer sheath.

14. The method of claim 13, further comprising configuring the introducer sheath with a drainage tube.

15. The method of claim 14, further comprising intermittently flushing and draining a patient'"'"'s bladder.

16. The method of claim 1, further comprising providing the delivery device with a snaring structure, and snaring connectors attached to the first and second distal anchors.

17. The method of claim 16, further comprising joining snared connectors.

18. The method of claim 1, wherein the first and second anchors are defined by barbed sutures.

19. A system for creating a continuous indentation in a prostatic urethra, comprising:

a delivery device, the delivery device including at least a first projecting needle and a second projecting needle;

a first distal anchor component and a second distal anchor component each housed within and deployable by the delivery device; and

at least one proximal anchor component attached to each of the first and second distal anchors.

20. The system of claim 19, wherein the delivery device is configured to project the needles to equal lengths.

21. The system of claim 19, wherein the delivery device projects the needles to different lengths.

22. The system of claim 19, wherein the delivery device includes a first needle housing receiving the first needle and the second needle housing receiving a second needle.

23. The system of claim 22, wherein the first and second housings are arranged in a parallel manner.

24. The system of claim 22, wherein the first and second housings are arranged in a divergent manner.

25. The system of claim 22, wherein the first and second housings are arranged in a crossing manner.

26. The system of claim 19, further comprising an introducer sheath and a drainage assembly attached to the introducer sheath.

27. The system of claim 19, wherein the delivery device includes a snare wire configured to capture and attach connectors extending from the first and second distal anchors.

28. The system of claim 19, further comprising a first proximal anchor and a second proximal anchor.

29. The system of claim 28, wherein the first proximal anchor is attached to the first distal anchor by a first connector segment and the second proximal anchor is attached to the second distal anchor by a second connector segment.

30. The system of claim 19, further comprising a single proximal anchor connected to each of the first and second distal anchors by a connector.

31. The system of claim 19, wherein each of the proximal and distal anchors define split members.

32. The system of claim 19, further comprising an anchor assembly defined by a repeating anchor component along its length.

33. The system of claim 19, wherein the anchor assembly includes a locking structure permitting the anchor assembly to define a closed configuration.

34. The system of claim 19, wherein the proximal anchor includes a bar with two spaced holes, each spaced hole configured to receive a connector extending from one of the first and second distal anchor components.

35. The system of claim 19, further comprising an anchor assembly defined by a curved wire having a length and curvature sized and shaped to span a lobe of a prostate lobe.

36. The system of claim 19, further comprising an anchor assembly including a circular loop formed from flexible material.

37. The system of claim 19, further comprising an anchor assembly including a hoop which expands in width as it contracts.

38. The system of claim 19, further comprising an anchor assembly including an extendable coil.

39. The system of claim 19, further comprising an anchor assembly including an umbrella-like frame.

40. The system of claim 19, further comprising an anchor assembly including prongs adapted to extend longitudinally in a compressed state and perpendicular to a longitudinal direction in a relaxed state.

41. The system of claim 19, further comprising an anchor assembly including a corkscrew body.

42. A method for increasing a luminal opening of a urethra, comprising:

inserting an anchor delivery device within the urethra; and

actuating the anchor delivery device to implant a first anchor within tissue outside of the urethra and to implant a second anchor having an anchor maximum length in a location to increase the luminal opening of the urethra such that the luminal opening is increased along a length greater than the anchor maximum length.

43. The method of claim 42, wherein the second anchor is implanted within the urethra.

44. The method of claim 42, wherein the first anchor is implanted in contact with prostatic tissue.

45. The method of claim 42, wherein the luminal opening is increased along a length 30% greater than the second anchor.
