Title: Innovations by James J Wang in Medical Device Technology

Introduction

James J Wang is a notable inventor based in San Marino, California, with a remarkable portfolio of seven patents. His work primarily focuses on enhancing medical device technology through innovative materials and coatings that improve the functionality and safety of these devices.

Latest Patents

One of Wang's latest patents involves the development of ultrasound responsive micro-composite markers. This technology utilizes ultrasound imaging, which is a non-invasive and cost-effective method for diagnosing and identifying implantable medical devices in real time. The innovation includes creating new ultrasound-activated coatings that expand the utility of in vivo marking by ultrasound imaging. The macro-phase segregated micro-composite thin films developed for this purpose are designed to be coated on medical devices made from various materials and shapes. These films, which contain silica micro-shells in polycyanoacrylate, produce strong color Doppler signals when used with standard clinical ultrasound transducers. Electron microscopy has revealed macro-phase separation during the slow curing of the cyanoacrylate adhesive, where air-filled silica micro-shells rise to the surface. The air trapped in these shells acts as an ultrasound contrast agent, allowing for effective imaging.

Another significant patent by Wang involves fluorescent and/or near-infrared (NIR) coatings for medical objects, which provide a composition for coating medical devices. This composition includes a polymeric matrix that contains non-toxic quantum dots or fluorophores, which bind to the medical device. The coated devices can be easily identified during surgeries, whether open or laparoscopic, significantly reducing the risk of retained foreign objects.
