Title: William L. Creer: Innovator in Vascular Prosthesis
Introduction
William L. Creer, a prolific inventor based in Phoenix, Arizona, has made significant contributions to the field of biomedical engineering with a focus on vascular prostheses. With a total of five patents to his name, Creer's work is instrumental in improving medical technology and patient care.
Latest Patents
Among his latest patents, Creer has developed a method for creating large diameter vascular prostheses and a vascular prosthesis made by said method. This innovative approach utilizes ePTFE (expanded polytetrafluoroethylene), allowing for prostheses with larger diameters and thinner walls than previously possible through traditional ram extrusion techniques. The method involves extruding a PTFE tube and processing it into an ePTFE tube, which undergoes lateral dilation in incremental steps. Each dilation step is followed by calendering the tube while maintaining it at an elevated temperature. Once dilated, the tube may be sintered with another to create a laminate, or a wire stent may be combined with one or more tubes to ensure the laminate retains a cylindrical shape.
