Abstract

An implant system including a transurethral prostatic implant positioned in a prostate and including a lumen with an inner perimeter that surrounds an outer perimeter of a urethra at the prostate. The implant system may include a delivery tool including a shaft having a distal portion and an implant-holding portion proximal to the distal portion, the distal portion being sized for entry into a urethra, and the implant-holding portion being thicker than the distal portion, and an implant positioned on the implant-holding portion.

Claims (16)

1. An implant system comprising:

a delivery tool comprising a shaft having a distal portion and an implant-holding portion proximal to the distal portion, said distal portion being sized for entry into a urethra, and said implant-holding portion being thicker than said distal portion; and

an implant positioned on said implant-holding portion, said implant having a lumen with an inner perimeter greater in size than an outer perimeter of the urethra.

2. The implant system according to claim 1 , wherein said implant comprises a plurality of coils configured to corkscrew into tissue.

3. The implant system according to claim 2 , wherein said coils are continuous to one another.

4. The implant system according to claim 2 , wherein said coils are coated with a substance.

5. The implant system according to claim 2 , wherein at least one of said coils is energized to deliver RF energy.

6. The implant system according to claim 2 , wherein at least one of said coils is energized to provide thermal energy.

7. The implant system according to claim 2 , wherein said implant-holding portion is formed with screw threads corresponding to a pitch between said coils, and said implant is initially positioned on said screw threads.

8. The implant system according to claim 7 , wherein a shoulder is formed at a junction of said distal portion and said implant-holding portion.

9. The implant system according to claim 1 , wherein said delivery tool comprises a hollow lumen for passing therethrough at least one of a substance and a tool.

10. The implant system according to claim 1 , wherein said shaft comprises a hollow lumen in fluid communication with a plurality of holes formed on a side wall of said shaft.

11. The implant system according to claim 10 , further comprising a suction device in fluid communication with said holes that are on the side wall of said shaft.

12. The implant system according to claim 1 , further comprising an implanting tool that includes a spiral pusher adapted for screwing onto said implant-holding portion of said shaft by rotation about a longitudinal axis of said shaft.

13. An implant system comprising a transurethral prostatic implant positionable in a prostate and including a lumen with an inner perimeter sized to surround an outer perimeter of a urethra at the prostate.

14. The implant system according to claim 13 , wherein said implant comprises a plurality of coils configured to corkscrew into tissue.
