Title: Kazuhiro Maruyama: Innovator in Stent Manufacturing
Introduction
Kazuhiro Maruyama is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of medical devices, particularly in the development of stents. With a total of 7 patents to his name, Maruyama's work focuses on enhancing the effectiveness and reliability of stent manufacturing.
Latest Patents
Maruyama's latest patents include a manufacturing method of a stent and a coating device. This innovative manufacturing method prevents a drug from being peeled off or separated due to stress concentration or distortion that occurs during the stent's expanding deformation. The method ensures that the drug remains uniformly effective, leading to improved yields during stent production. Additionally, the coating device features a non-coating portion forming process that prevents the bending portion of the stent from being coated with the drug. This is achieved by allowing the nozzle to bypass the bending portion while reducing the adhesion amount of the coating solution.
Another significant patent is for a stent with a drug coat layer designed to minimize strain and stress concentration during expansive deformation. This stent includes a body and a drug coating layer that gradually decreases in thickness toward the bent portion, thereby reducing the risk of drug separation.
Career Highlights
Throughout his career, Kazuhiro Maruyama has worked with prominent companies such as Terumo Corporation and Sony Corporation. His experience in these organizations has contributed to his expertise in medical device innovation and development.
