Title: Innovations by Marc S. Cohen in Controlled Release Technologies
Introduction
Marc S. Cohen is an accomplished inventor based in Gainesville, Florida. He has made significant contributions to the field of controlled release technologies, holding a total of four patents. His work focuses on developing innovative methods and devices that enhance the delivery of biologically active agents.
Latest Patents
One of Marc S. Cohen's latest patents involves compositions and devices for the controlled release of active ingredients. This method utilizes a hydrophobic, pH-sensitive polymer matrix that releases the active agent when the environment reaches a pH of 8.5. The polymer matrix swells in response to this pH change, allowing for the gradual release of the active agent. In another embodiment, the system employs weakly basic comonomers, releasing the active agent as the pH drops. A specific application of this technology is in ureteral catheterization, where the pH-sensitive polymer is coated onto latex catheters. This innovation addresses the common issue of urinary tract infections caused by urease-producing bacteria in catheterized patients. The polymer can release an antibiotic or urease inhibitor when exposed to high pH urine, maintaining effective drug levels for a clinically useful duration. Other potential applications for this technology include gastrointestinal tubes, respiratory trap lines, dye-releasing sutures, and even contact lenses.
