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.
