Adjustable trans-urethral radio-frequency ablation
First Claim
1. A device for enlarging a urethral passage, comprising:
- an elongate member having a distal portion configured for intraurethral placement in the urethral passage, and an electrode at the distal portion of the elongate member configured to be energized with high frequency energy to necrose tissue of the urethral wall and surrounding prostate tissue to form a cavity in the urethral passage, the electrode having an adjustable working length.

Abstract
A device for enlarging a urethral passage includes an elongate member having a distal portion configured for intraurethral placement in the urethral passage, and an electrode at the distal portion. The electrode is configured to be energized with high frequency energy to necrose tissue of the urethral wall and surrounding prostate tissue to form a cavity in the urethral passage. The electrode has an adjustable working length. The electrode has a diameter greater than about 16 French to substantially occlude the urethra. The device includes multiple electrodes spaced apart a distance of about 1 to 5 mm to provide flexibility in the distal portion of the elongate member. A method of treating a urethral passage includes measuring a length of a patient'"'"'s prostate, and selecting a length of an electrode based on the measured length of the prostate.
