Latest Patents

Yu-Chun Ku's latest patents showcase his innovative spirit and technical expertise. The first patent, titled "Pulsed Fiber Laser Cutting System for Medical Implants," introduces a groundbreaking method for creating an improved expandable stent for implantation in body lumens, such as arteries. The stent consists of multiple radially expandable cut cylindrical elements aligned along a common axis and interconnected by one or more interconnective elements. Notably, these elements feature a rectangular cross-section from cut-to-cut and an undulating pattern. This stent is manufactured through direct laser cutting of a single metal tube using a finely focused laser beam from a diode-pumped fiber laser. The process allows for precise control of the tube's linear and rotary velocity, with adjustable laser parameters to optimize the cut.

The second patent, "Apparatus and Method for Electropolishing Surfaces," offers an innovative method and apparatus for electropolishing a workpiece without the need for immersion in an electrolytic solution bath. In this method, the workpiece is held in an atmospheric environment, and electrolytic solution is discharged as jet streams onto its surface while a voltage difference induces current flow between the workpiece and jet streams. This process causes anodic dissolution, effectively polishing the workpiece surface. Furthermore, the electrolytic solution can be collected, filtered, cooled, and recycled, promoting sustainability.
