Urethral probe device

摘要

An urethral probe device for treatment of prostate hyperplasia comprises an elongated tube (12) extending between a distal end (12c) and a proximal end (12a) to be inserted into the urethra towards the prostate. A catheter probe (11) having an elongated body with a circumferential surface, a distal end (11c) and a proximal end (11a) is movably accomodated within the urethral probe. The elongated body has a longitudinal bore (11b) extending from the distal end towards an outlet opening (11d) in the circumferential surface near the proximal end. A catheter tube (13) having a distal end and a proximal sharp end (13a) is inserted with its sharp end through the longitudinal bore, the outlet opening and through the urethral wall into the prostate. The catheter tube includes means for delivering a certain pre-planned amount of radiation energy to at least one location within the prostate for effecting radiation treatment. The urethral probe allows a quick and more accurate positioning of the catheter probe and the catheter tube relative to the prostate without discomforting the patient. <IMAGE>
