Title: Innovations by Edward Wilson Merrill
Introduction
Edward Wilson Merrill is a notable inventor based in Cambridge, MA (US). He has made significant contributions to the field of medical devices, particularly in the development of advanced contact lenses and catheters. With a total of 2 patents to his name, Merrill's work showcases his expertise and innovative spirit.
Latest Patents
Merrill's latest patents include a groundbreaking design for a contact lens that features a smooth surface layer of a hydrophilic polymer. This contact lens comprises a silicone polymer or copolymer core, with a hydrophilic polymer surface grafted to the core. The innovative process involves contacting the silicone with a free radical polymerizable precursor in a liquid state and exposing it to a high dose of ionizing radiation for a short period. This method ensures the production of an optically clear contact lens by forming a smooth surface of the polymer grafted to the silicone, while preventing substantial migration of the precursor into the silicone.
Another significant patent by Merrill is for a silicone catheter that is rendered hydrophilic. This is achieved by contacting the catheter with N-vinyl pyrrolidone (NVP) in bulk or in solution and exposing both the catheter and NVP to ionizing radiation at a high dose rate. The careful control of the radiation dose and the concentration of NVP prevents penetration beyond a thin surface layer, enhancing the catheter's functionality.
