Title: Biocompatible materials
Usefulness: Biocompatible materials
Summary: USE The PL conjugated material is of use for a wide variety of medical and surgical devices and equipment. Examples in surgery are implants (e.g. for breast or ear), prostheses, vascular grafts, stents, stomach ports, heart valves, or any artificial part or device which replaces or augments a part of a living body or comes into contact with bodily fluids, esp. blood. Medical device examples are catheters, e.g., drain or angioplasty balloon, sutures, tubing, as in extracorporeal circuitry, membranes, as for haemodialysis or biosensors, needles, guide wires, blood pumps or filters, or diagnostic devices. A wide variety of materials, provided that the surface is modified to react with the PL, can be treated by the method; these include stainless steel, glass or other inorganics, and organic polymers, esp. polypropylene and polytetrafluoroethylene.
Novelty: Biocompatible materials linked to phospholipid moieties provides improved non-thrombogenic surface, used for implants, prostheses, vascular grafts, and medicinal and surgical devices
