Abstract

Devices, systems and methods for compressing, cutting, incising, reconfiguring, remodeling, attaching, repositioning, supporting, dislocating or altering the composition of tissues or anatomical structures to alter their positional or force relationship to other tissues or anatomical structures. In some applications, the invention may be used to improve patency or fluid flow through a body lumen or cavity (e.g., to limit constriction of the urethra by an enlarged prostate gland).

Claims

1. A method for treating prostatic tissue by inducing tissue remodeling with an implant delivery system, comprising:

accessing an interventional site adjacent prostatic tissue with the delivery system;

positioning at least a portion of a retaining member outside the prostatic capsule; and

reducing blood flow to tissue within the prostatic capsule.

2. The method of claim 1 wherein the reducing step comprises maintaining compression on prostatic tissue.

3. The method of claim 1 further comprising inducing atrophy in prostatic tissue.

4. The method of claim 1 further comprising inducing necrosis in prostatic tissue.

5. The method of claim 2 wherein compression is maintained for at least one month.

6. The method of claim 2 wherein compression is maintained for at least three months.

7. The method of claim 2 wherein compression is maintained for at least six months.

8. The method of claim 1 wherein the retaining member is bioabsorbable.

9. The method of claim 2 further comprising determining the extent of compression of prostatic tissue.

10. The method of claim 9 wherein the extent of compression of prostatic tissue is determined by visual inspection of displacement of the prostatic urethra.

11. A method for causing a therapeutic effect in prostatic tissue with an implant delivery system, comprising:

accessing an interventional site adjacent prostatic tissue with the delivery system;

deploying at least a portion of an implant to an outer surface of the prostatic capsule;

locally compressing prostatic tissue; and

maintaining compression of prostatic tissue via the implant for an amount of time sufficient to induce tissue remodeling.

12. The method of claim 11 wherein the tissue remodeling is characterized by lobular atrophy.

13. The method of claim 11 wherein the tissue remodeling is characterized by necrosis.

14. The method of claim 11 wherein the tissue remodeling is characterized by reduced tissue volume within the prostatic capsule.

15. The method of claim 11 wherein the implant is bioabsorbable.

16. The method of claim 11 wherein the implant compresses the prostatic tissue.

17. The method of claim 11 wherein the delivery system compresses the prostatic tissue.

18. The method of claim 11 further comprising determining the extent of compression by visually inspecting the interventional site.

19. A method of treating a prostate comprising positioning an implant at least partially outside a capsule of the prostate, wherein the position of the implant is maintained for a time sufficient to induce lobular atrophy.

20. The method of claim 19 wherein positioning the implant maintains compression on prostatic tissue.
