Latest Patents
One of Estep's latest patents is focused on biocompatible surfaces and a method for their preparation. This innovative approach involves a novel group of compounds designed to decorate the surfaces of synthetic polymeric or tissue-derived prostheses. The goal is to prevent adverse rejection events by using decorating molecules derived from naturally occurring polysaccharides. These molecules are modified to provide functionally reactive groups, allowing for a simple one-step reaction with the prosthesis surface. Additionally, some of these reagents are effective for noncovalent adsorption to polyolefinic or perfluorocarbon-based materials. Another significant patent involves the preparation of pharmaceutical-grade hemoglobins through heat treatment. This method selectively precipitates uncrosslinked hemoglobin while purifying crosslinked hemoglobin, resulting in a product that is free of chromatography fines and has a low methemoglobin content.
