The Spanner® Prostatic Stent is a temporary stent inserted into the urethra at the neck of the bladder to maintain urine flow. The Spanner benefits men with bladder outlet obstruction (BOO) by reducing elevated post void residual (PVR), improving voiding symptoms, and allowing for voluntary urination. As an alternative to a Foley Catheter, it allows men to naturally fill and empty their bladders.
Key Benefits of The Spanner
Clinically proven to accurately measure voiding pressure.
Normal micturition achieved with bladder and sphincter.
Simple and quick to perform.
Improves urination efficiency by decreasing urine left in the bladder.
Reduces rate of bacterial colonization compared to the Foley catheter.
Well tolerated by patients.
Improves IPSS scores.
Greatly preferred by patients over catheterization.
How It Works
The Spanner® Prostatic Stent has been designed to open the prostatic urethra and allow patients to maintain urine flow and allow volitional voiding by reducing urethral resistance within the prostate. As shown in the figure to the left The Spanner has a proximal balloon that is seated in the bladder neck to properly position the stent in the prostatic urethra. The stent extends from the bladder to just above the external sphincter. Device tethers (suture material) traverse the external sphincter to allow normal sphincter function, thus providing patients the ability to volitionally void. The distal anchor of the device is positioned in the bulbar urethra, just below the sphincter, to prevent device movement and migration into the bladder.
