  • Patent number: 10582920
    Abstract: Examples of a suture anchor (100) having a non-expandable body (105) and expendable cap (110) are described herein. In response to an axial insertion force that brings the non-expandable body and expendable cap together inside a bone hole, the expendable cap expands radially. This creates a radial force of expansion that advantageously augments an interference fit between the suture anchor and bone hole, which leads to higher fixation strength. Other examples include retention features that inhibit the expendable cap from returning back into its unexpanded state. This advantageously maintains the radial force of expansion against the surrounding pressure of the walls of the bone hole pressing back on the suture.

  • Patent number: 8753344
    Abstract: A dynamic sensing method and apparatus employs microelectromechanical systems (MEMS) and nanoelectromechanical (NEMS) surgical sensors for gathering and reporting surgical parameters pertaining to a drive mechanism of a surgical device, such as speed, rotation, torque and other characteristics of the surgical device. The surgical device employs or affixes the surgical sensor on or about a surgical device for detecting electromechanical characteristics during the surgical procedure. The surgical procedure disposes the medical device in the surgical field responsive to the drive mechanism of a shaver or other endoscopic instrument inserted in a surgical field defined by the surgical procedure.

  • Publication number: 20140135806
    Abstract: Featured is a surgical instrument having an elongate inner tubular member and an elongate outer tubular member, in which the inner tubular member is moveably received within the outer tubular member. The instrument also includes a diamond-like carbon (DLC) surface disposed so as to be between the inner and outer tubular members. In further embodiments, the DLC surface is formed on the outer surface of the inner tubular member and/or on the inner surface of the outer tubular member. In yet further embodiments, the inner tubular member includes a cutting edge disposed at a distal region thereof, and the outer tubular member includes a distal opening therein. The opening is positioned to expose and co-operate with the cutting edge of the inner tubular member to permit shearing or cutting of tissue.
