PARTIAL (NON-APICAL) PROSTATE ABLATION PROCEDURE AND DEVICE

摘要

A device and procedure for performing partial non-apical transurethral ablation of the prostate. The device includes a first conductor member reciprocably extending from a distal end of a sheath, a cap disposed at the distal end of the first conductor member, at least two nonconducting members interconnecting the cap and the distal end of the sheath, and multiple flexible conductor members distally extending from the distal end of the sheath, along the first conductor member, and interconnected with the distal end of the first conductor member. The device is operable to expand the nonconducting members and the flexible conductor members to perform ablation of a lower region of the prostatic urethra while an upper (apex) region of the prostatic urethra is held apart from the lower region by the nonconducting members so that the upper (apex) region does not undergo ablation.
