Title: Ralph S. Greco: Innovator in Biomaterials
Introduction
Ralph S. Greco is a notable inventor based in Basking Ridge, NJ (US), recognized for his contributions to the field of biomaterials. With a total of 5 patents, Greco has made significant advancements that enhance the functionality and safety of medical devices.
Latest Patents
One of Greco's latest patents is the "Thromboresistant surface treatment for biomaterials." This invention provides a biomaterial with a thromboresistant surface, achieved through a distinct coating layer of a chitosan-based membrane combined with a biologically active material. This innovative approach allows the chitosan membrane to transition from a highly thrombogenic state to an essentially non-thrombogenic one. The biologically active material can be a polymeric substance, such as polyvinyl alcohol, or a biological substance like serum albumin, which is embedded in or attached to the chitosan membrane activated with glutardialdehyde. This thromboresistant biomaterial is particularly suitable for vascular grafts with an inside diameter of less than 6 millimeters.
Another significant patent is the "Drug bonded prosthesis and process for producing same." This invention describes an improved prosthesis that is coated with an anionic surfactant and a drug, such as an antibiotic or antithrombotic agent. The prosthesis may also undergo treatment with an ion exchange compound to eliminate un-drug bound anionic surfactant, ensuring that the drug is effectively bound to the surfactant-coated prosthesis.
