Recombinant Spider Silk Protein Coatings for Intravenous Catheters

Technical Summary

•  Intravenous (IV) catheters suffer from a variety of problems including, for example: 1) thrombotic occlusion (blood clot blocking passage of blood or therapy into our out of the catheter), 2) fibrin sheath deposition (fibrin sheath that occludes the catheter), and 3) infection either at the site of insertion or biofilm deposition that leads to systemic infections. Coating the IV catheter with recombinant spider silk proteins (rSSp) combats thrombosis and associated thrombotic occlusions and may also help resist fibrin sheath deposition.

 

Commercial Applications

•  Potential commercial partners:

•  Catheter development companies

•  Biomedical/Biotech companies

 

Competitive Advantages       

•  Elimination or reduction of infections relating to catheters.

•  rSSp coating adheres to silicone and polyurethane along with a variety of other materials.

•  Coatings can be functionalized with antimicrobials.
