## Abstract

Devices, systems and methods for retracting, lifting, compressing, supporting or repositioning tissues, organs, anatomical structures, grafts or other structures within the body of human or animal subjects for the purpose of treating a diseases or disorders and/or for cosmetic or reconstructive purposes and/or for research and development purposes or other purposes.

## Claims

### Claim 1

A method for causing a desired alteration of volitional or non-volitional flow of a body fluid through a urethra of the body of a human or animal subject whose prostate is enlarged such that it has caused a constriction of the urethra thereby interfering with normal micturition, said method comprising the steps of:
A) positioning a first anchor having a tensioning element attached thereto to engage an exterior portion of the prostate;
B) selecting a location on a tensioning member from a plurality of locations each of which will result in a different amount of tension on the tensioning member; and
C) attaching a second anchor to said tensioning member at a selected location on said tensioning member whereby the second anchor engages an interior portion of the prostate, said selected location resulting in an amount of tension that causes the desired alteration of volitional or non-volitional flow of a body fluid through the lumen.

### Claim 2 (depends on 1)

A method according to claim 1 wherein the first anchor is implanted such that it engages an outer aspect of the prostatic capsule.

### Claim 3 (depends on 1)

A method according to claim 1 wherein the first anchor is implanted such that it is within the prostatic capsule.

### Claim 4 (depends on 1)

A method according to claim 1 wherein the first anchor is implanted such that it engages prostate tissue located inside the prostatic capsule.

### Claim 5 (depends on 1)

A method according to claim 1 wherein the second anchor is implanted within the urethra.

### Claim 6 (depends on 1)

A method according to claim 1 wherein the second anchor is implanted within the urethral wall.

### Claim 7 (depends on 6)

A method according to claim 6 wherein the second anchor is constructed and implanted such that it becomes overgrown with tissue such that urine flowing through the lumen of the urethra does not directly contact the second anchor.

### Claim 8 (depends on 1)

A method according to claim 1 wherein the second anchor is implanted within the prostate tissue located outside of the wall of the urethra.
