Triangular Prostatic Stent (TPS)

During the last two decades, the use of prostatic stents has started to become an alternative to indwelling catheters or even to surgery. The adaptation of existing vascular stents for different non-vascular conditions created a gap in the market for site and disease-specific stents that are designed precisely to the anatomy and physiology of the organ to be treated.

The TPS range has a large calibre triangular cross-section to match the contours of the prostatic urethral lumen allowing it to exert varying degrees of radial force depending on the anatomy. For example, higher radial force in its main body and lower radial force in the area near the external sphincter to prevent sphincteric dysfunction. These characteristics enable the TPS to conform to the prostatic urethra, allow an excellent flow and offer a much improved comfort than existing stents, without jeopardising the voluntary continence mechanism.
