The Targis microwave system by Urologix® is a non-surgical device developed to relieve symptoms associated with benign prostatic hyperplasia (also referred to as BPH—a noncancerous enlargement of the prostate gland). The one-hour procedure is typically performed by a urologist who inserts a flexible catheter into the urethra. Within the catheter, a microwave exists which creates high temperatures in order to destroy the diseased over-grown prostate tissue. While this procedure is occurring, at the same time, the catheter cools and protects the nearby healthy tissue in order to minimize complications and discomfort following the procedure. The Targis treatment is done on an out-patient basis and does not require anesthesia.
