Innovation That Matters
Zwitterionic molecules create a hydration barrier that repels proteins and bacteria. Designed for:
Infection Resistance
Biofilm reduction without antibiotics or antimicrobials.
Reduced Encrustation
Fewer blockages, fewer replacements, reduced trauma.
Cost Efficiency
Decrease complication-related expenses.
Enhanced Comfort
Superior lubricity for patient wellbeing.
Treatment Effect Demonstration
ClearTract SPT® Specialty Foley Catheters
Drug-free surface treatment designed to reduce infections and encrustation, and improve patient comfort.
The first time this SILQ catheter was used we saw an immediate improvement. This has been a life-changing event for not only Nathan, but also his group home and us.
