Latest Patents
O'Brien's latest patents include innovative techniques for making closed-end tubes for surgical instruments. These techniques involve creating one-piece tubes where an inner tube, which carries a cutting implement, is designed to move within an outer tube that features a cutting window. This design allows the cutting implement to effectively interact with tissue during surgical procedures. The process includes swaging to close one end of the tubular member, which can serve as either the inner or outer tube. Additional processing steps involve cutting away a protrusion formed by the swaging, fusing the tube material at a seam, and shaping the closed distal end into a selected form. This versatility allows the tubes to be suitable for various surgical instruments, whether they require a rounded or flattened distal end.
Another significant patent involves a lubricant for forming ferrous metal blanks into specific configurations through warm- or hot-forming procedures. This lubricant is an alkali-modified borate glass that is created in situ on the surface to be lubricated. By heating a mixture of boron oxide and alkali metal borate, the glass is formed, enhancing the metal forming process.
