## Indications for use
The Lighthouse TM Urinary Catheter is intended for bladder/urinary tract drainage during prostate brachytherapy procedures where transrectal ultrasound (TRUS) imaging is used to visualize the prostate. The catheter additionally enhances identification of the course of the posterior aspect of the prostatic urethra during TRUS-guided brachytherapy by creating an acoustic interface (i.e., air) between the catheter and the urethral wall via its urethral identification bladder.
