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 comprising, distracting and/or retracting the lobes of a prostate.

Claims

1. A method for treating benign prostatic hypertrophy having an enlarged median lobe, comprising:

implanting a first anchor on a first side of the median lobe; and

implanting a second anchor on a second side of the median lobe with a connector between the first and second anchors to retract the median lobe away from an urethra opening to increase luminal area.

2. The method of claim 1, further comprising inserting an anchor delivery device within the urethra;

actuating the anchor delivery device.

3. The method of claim 2, further comprising incorporating a depth sensor or indicator into the anchor delivery device so that penetration of a rectum is avoided.

4. The method of claim 1, further comprising removing the anchor delivery device from the urethra.

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

6. The method of claim 1, further comprising advancing the anchor delivery device into an ejaculatory duct.

7. The method of claim 1, further comprising forming a channel in the median lobe with an anchor delivery device.

8. The method of claim 7, further comprising rotating the anchor delivery device and actuating the anchor delivery device to eject a needle assembly through the median lobe.

9. The method of claim 8, further comprising manipulating the anchor delivery device to implant the first anchor.

10. The method of claim 9, further comprising causing the anchor delivery device to implant the second anchor.

11. The method of claim 10, further comprising again rotating the anchor delivery device and deploying a second anchor assembly across the median lobe.

12. The method of claim 11, further comprising further rotation of the anchor delivery device and implanting one or more subsequent anchor assemblies across the median lobe.

13. The method of claim 12, further comprising creating one or more permanent valleys through the median lobe.

14. The method of claim 1, further comprising advancing a needle assembly through the ejaculatory duct and the median lobe.

15. The method of claim 14, further comprising implanting the first anchor within the urinary bladder and in apposition with the median lobe.

16. The method of claim 15, further comprising implanting the second anchor within the ejaculatory duct.

17. The method of claim 16, further comprising rotating the anchor delivery device.

18. The method of claim 17, further comprising implanting a second anchor assembly from the ejaculatory duct and across the median lobe.

19. The method of claim 1, further comprising anchoring the median lobe to the pubic symphysis.

20. The method of claim 1, further comprising anchoring the median lobe to the detrusor muscle.

21. A method for treating benign prostatic hypertrophy, comprising:

assessing an anatomy of a median lobe;

actuating an anchor delivery device to implant a first anchor on a first side of the median lobe and a second anchor on a second side of the median lobe to thereby retract the medial lobe to increase luminal flow through an urethra; and

removing the anchor delivery device from the urethra.

22. The method of claim 21, further comprising taking an extra-urethral approach to implant an anchor assembly across the median lobe.

23. A method for treating benign prostatic hypertrophy, comprising:

assessing an anatomy of a median lobe;

activating an anchor delivery device to implant first and second anchors on a first side of a median lobe and a third anchor on a second side of a median lobe to increase luminal flow through a urethra, wherein the first and second anchors are placed to create a 6 o'"'"'clock net force displacement of the median lobe; and

removing the anchor delivery device from the urethra.

24. The method of claim 23, further comprising implanting a fourth anchor on the second side of the median lobe.
