Abstract

A system and associated method for altering or destroying tissues and anatomical or other structures in medical applications for the purpose of treating diseases or disorders. In one aspect, the system includes a device configured to deploy devices for altering the lobes of a prostate.

Claims

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

assessing an anatomy of a median lobe;

inserting a treatment device within a urethra, the treatment device includes an extendable needle and an elongate member advanceable through the extendable needle, wherein the elongate member includes a curved cutting blade;

actuating the treatment device to advance the needle within the median lobe to form a penetration track; and

advancing the elongate member beyond the needle while the needle is within the median lobe to capture, separate, cut, dissect and/or remove tissue of the median lobe.

2. The method of claim 1, further comprising advancing the treatment device into an ejaculatory duct.

3. The method of claim 1, further comprising applying energy to the median lobe to destroy tissue.

4. The method of claim 3, wherein the energy is microwave energy.

5. The method of claim 1, further comprising cauterizing median lobe tissue.

6. The method of claim 1, further comprising applying a vacuum to remove tissue from the median lobe.

7. The method of claim 1, wherein the elongate member includes a rotatable helical blade, further comprising rotation of the helical blade.

8. The method of claim 1, wherein the elongate member includes articulating cutting arms and further comprising articulating the arms to cut median lobe tissue.

9. The method of claim 1, wherein the elongate member includes an expandable cutter and further comprising expanding the cutter to cut median lobe tissue.

10. The method of claim 1, wherein the elongate member includes a blunt dissector and further comprising dissecting median lobe tissue with the dissector.

11. The method of claim 10, wherein the blunt dissector further includes a cutter blade.

12. The method of claim 1, wherein the elongate member includes a ligature and further comprising configuring the ligature about the median lobe.
