A sterile non-bioabsorbable tubular device intended to be placed short-term (<= 30 days) in the urethra to facilitate urethral patency and an unimpeded flow of urine from the bladder; it is typically used to relieve lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH). It is made entirely of metal [e.g., nickel-titanium alloy (Nitinol)] and is typically self-expanded in situ; disposable devices intended to assist implantation or removal (e.g., attached thread) may be included.
