Latest Patents
Walder's latest notable patents include:
1. **Method for rendering a substrate surface antithrombogenic** - This invention details a method for rendering a medical article antithrombogenic and/or anti-infective. It involves coextruding a base polymer with a hydrophilic laminating polymer that contains a quarternary salt complexing agent. The process includes steeping the extruded article in an aqueous solution of an antithrombogenic and/or anti-infective reagent, allowing for the absorption of the reagent along with water by the hydrophilic polymer which then reacts with the complexing agent.
2. **Catheter obturator with automatic feed and control** - This device is designed to facilitate the placing and withdrawing of a catheter obturator over extended periods. It provides the means to occlude the catheter lumen without the need for cumbersome saline and heparin locks while ensuring that the internal functioning remains sterile throughout its use. The obturator includes a special coating that reacts with aqueous fluids to seal the catheter lumen effectively, incorporating heparin to prevent clotting.
