Its primary purpose is to support narrowed or damaged urinary tracts and to drain urine. It is suitable for patients who require long-term (from several months to one year) urinary diversion or urinary tract support. Made from high-purity medical-grade silicone, this device exhibits excellent biocompatibility and anti-encrustation properties, making it an ideal choice for long-term placement scenarios.
