Slippery coating for dialysis catheters to prevent clots and infection
Slippery Omniphobic Coating for Hemodialysis Catheter to Resist Fibrin Sheathing and Infection and Improve Patient Outcomes

What this research studies
If I have a dialysis catheter, this project is developing a slippery, non-stick coating called tethered liquid perfluorocarbon (TLP) to keep blood, bacteria, and fungi from sticking to the catheter surface. The work focuses on optimizing the coating for use on hemodialysis catheters through laboratory and preclinical testing. The aim is to stop fibrin sheath and biofilm formation that lead to catheter clotting and infections. The company plans to adapt the coating for commercial catheters so fewer patients need catheter replacement, antibiotics, or hospital care.
Who could benefit from this research
Good fit: Adults who are receiving hemodialysis with a central venous catheter or who are expected to use a catheter at dialysis initiation would be the ideal candidates.
Not a fit: People who do not use dialysis catheters (for example those with mature fistulas or grafts) and pediatric patients are unlikely to benefit directly from this project.
Why it matters
Potential benefit: Could lower rates of catheter-related bloodstream infections and thrombosis, reducing hospital visits and catheter replacements for dialysis patients.
How similar studies have performed: Non-stick and antifouling coatings have shown promise in laboratory and animal studies, but there is not yet an approved catheter coating that fully prevents both clotting and infection in patients.
