  • Patent number: 9198776
    Abstract: An osteotome suitable for cutting through cancellous bone that is holding an orthopaedic implant requiring revision within a cavity of a bone, includes a cylindrical waveguide connectable to a source of ultrasonic vibrations at its proximal end and a blade having a hollow part-cylindrical cross-section and a cutting edge at its distal tip. The respective longitudinal axes of the waveguide and the blade cross at an angle of about 30°, and the waveguide and blade taper and curve smoothly together where they meet. The osteotome is dimensioned such that a first antinode of the ultrasonic vibrations is located at a proximal end of the waveguide, a second antinode is located at the distal tip of the blade and a node is located where the waveguide and blade meet. The osteotome cuts readily through cancellous bone when ultrasonically energized.

  • Patent number: 9095363
    Abstract: Embodiments described herein provide devices, systems, and methods that reduce the distance between two locations in tissue, often for treatment of congestive heart failure. For example, an anchor of an implant system may, when the implant system is fully deployed, reside within the right ventricle in engagement with the ventricular septum. The anchor may be deployed into the heart through a working lumen of a minimally invasive access tool. The minimally invasive access tool may have a plurality of grippers near a distal end of the working lumen. The grippers may engage epicardial tissue of the heart and may be moved radially inwardly relative so as to provide stabilization of the epicardial tissue and/or hemostasis near an access site where the anchor is inserted through the epicardium. The minimally invasive access tool may minimize blood loss from the access site and improve anchor implant processes.

  • Patent number: 9050004
    Abstract: A retractor instrument for minimally invasive surgery may include a housing with a longitudinal axis, an arm extending from a distal end of the housing, and an actuation mechanism, wherein actuation of the actuation mechanism causes radial expansion of the arm relative to the longitudinal axis. The device may be adapted for use with an endoscope or arthroscope or may be an integral part of one such scope. A method of performing surgery in constrained areas within the body is also included and may be applicable to the carpal tunnel of a wrist and palm or the cubital tunnel of an elbow.

  • Publication number: 20150141759
    Abstract: A surgical device includes a plurality of cameras integrated therein. The view of each of the plurality of cameras can be integrated together to provide a composite image. A surgical tool that includes an integrated camera may be used in conjunction with the surgical device. The image produced by the camera integrated with the surgical tool may be associated with the composite image generated by the plurality of cameras integrated in the surgical device. The position and orientation of the cameras and/or the surgical tool can be tracked, and the surgical tool can be rendered as transparent on the composite image. A surgical device may be powered by a hydraulic system, thereby reducing electromagnetic interference with tracking devices.

  • Patent number: 8979882
    Abstract: Described here are methods and devices for forming tracts in tissue. Some of the devices feature an elongate member, a suction member coupled to a distal portion of the elongate member, and a tissue-piercing member slidably housed within the elongate member for forming a tract in tissue. Other devices feature more than one suction member. Methods for forming tracts in tissue are also described here. In some methods, a device is advanced adjacent tissue, where the device features one or more suction members and a tissue-piercing member. Suction is applied so that the tissue is drawn against the one or more suction members, and a tissue-piercing member is advanced in a first direction through the drawn tissue to form a tract in or through the tissue. Kits incorporating one or more of the devices described here, in conjunction with one or more tools or the like, are also described here.

  • Publication number: 20150065808
    Abstract: An arthroscopic sealing cannula having improved efficiency, access and reduced manufacturing costs is described herein. In particular, the present invention describes arthroscopic sealing cannulae in which the conventional thermal and chemical bonding means are eliminated and replaced with a mechanical joining system that utilizes mating fastener pairs integrally molded into the distal and proximal elements of a cannula so as to thereby provide a strong reliable joining of the elements. Such a mechanical system eliminates the need for costly capital equipment and specializing tooling as well as the material and environmental handling problems associated with conventional bonding techniques. Furthermore, in that the join may be readily confirmed through simple visual examination, the present invention also eliminates the need for complex, costly, and time-consuming validation procedures mandated by regulations in place to ensure proper integrity, strength, and reliability of the bond.
