Patent number: 9597135Abstract: An inserter for a bone screw assembly includes a hollow outer shaft with an inner shaft concentrically disposed therein. The distal ends of the inner shaft and outer shaft each define a feature for engaging the bone screw assembly. A collar is concentrically disposed about the proximal end of the inner shaft and a rotational interface is provided between the collar and inner shaft. The rotational interface is configured so that rotation of the collar relative to the inner shaft moves the collar into abutting engagement with a hub defined at the proximal end of the outer shaft. This abutting engagement locks the inner and outer shafts together when the distal ends of the shafts are engaged to the bone screw assembly for use in introducing the bone screw assembly into a bone.Type: GrantFiled: September 22, 2012Date of Patent: March 21, 2017Inventors: Gregory A. Miller, Dennis L. Abernathie, Eric J. Lintula

Patent number: 9597136Abstract: An apparatus, for reinforcing bone and tools for mounting the same, has an implant including a barrel and a device. The implant can be expanded by an expanding apparatus including an outer tub, a base, a hollow body and a handle. The expanding apparatus can be bound to the implant to place the implant into a bone to be treated and adjust the expansion degree. The expanding apparatus can be replaced by an injector apparatus including a container for bone cement and an injecting handle. The injector apparatus can inject a mixture for reinforcing bone (e.g., bone cement) into the bone through an exit, the device, the aperture, the barrel and the window of the barrel, and into the to-be treated area.Type: GrantFiled: July 10, 2013Date of Patent: March 21, 2017Assignee: CHANG GUNG UNIVERSITYInventors: Shiuann-Sheng Lee, Wen-Jer Chen, Ching-Lung Tai, De-Mei Lee, Jiunn-Jong Wu, Chih-Ta Yu, Tsung-Hsin Wu, Sheng-Yu Lin

Patent number: 9597137Abstract: A bone filling device includes a catheter that defines a longitudinal axis and extends between a proximal end and a distal end. A first lumen extends along the longitudinal axis of the catheter and defines a first passageway. A second lumen extends along the longitudinal axis of the catheter and defines a second passageway. An inflatable body includes a wall that defines a fillable cavity. The fillable cavity is in fluid communication with the first passageway. A bone filler delivery port continuous with the second passageway and configured to dispense bone filling material.Type: GrantFiled: June 24, 2016Date of Patent: March 21, 2017Assignee: Kyphon SÀRLInventor: Craig E. Lauchner

Patent number: 9597138Abstract: A bone cement mixing and delivery system including a mixer, a delivery device, and a flexible extension tube. A connector is attached to a distal end of the flexible tube. The connector includes a housing, a fitting and an enlarged knob. A spindle that extends through the housing connects the fitting to the knob so the fitting rotates with the knob. A cannula is connected to the mixing and delivery system by placing the cannula fitting adjacent the connector fitting. The knob is rotated to result in the like rotation of the connector fitting. This causes the complementary threading on the connector fitting and the cannula fitting to engage.Type: GrantFiled: November 11, 2013Date of Patent: March 21, 2017Assignee: STRYKER CORPORATIONInventors: Jared P. Coffeen, Christopher A. Rossman

Patent number: 9597139Abstract: A system, devices and methods are provided for facilitating stabilization of periarticular fractures. The system includes a compression plate and one or more of a cerclage cable for encircling the bone and securing the compression plate to the bone, a crimp lug for securing the cable in tension relative to the bone and/or a plate, and a supplemental plate coupled to the compression plate and adapted to receive bicortical or unicortical bone screws to further secure the compression plate relative to the bone. In addition, the system includes a cable tensioner for temporarily retaining the cable in tension and then applying a tension to the cable until a desired compression is effected between a plate and bone and while a cable retaining structure is secured to the cable to retain the applied tension on the cable. Also provided is a jig for use with plates for minimally invasive fracture stabilization.Type: GrantFiled: February 27, 2013Date of Patent: March 21, 2017Assignee: Biomet C.V.Inventor: Cesare Cavallazzi

Patent number: 9597140Abstract: A device, system and method for temperature-based lesion formation assessment and mapping functionality using an accessory usable with an over-the-wire balloon catheter. The device may include a first annular element, a plurality of wires coupled to the first annular element, and a second annular element, the plurality of wires passing from the first annular element through the second annular element and into an elongate wire conduit coupled to the second annular element. At least one of the plurality of wires may include at least one temperature sensor and/or at least one mapping electrode. The first annular element coupled to an outer surface of a sheath. As a balloon catheter is advanced out of the sheath lumen, the distal tip of the catheter engages the second annular element and pushes the wires out of the sheath lumen, everting them over the balloon of the catheter.Type: GrantFiled: January 31, 2014Date of Patent: March 21, 2017Assignee: Medtronic CryoCath LPInventor: Teresa Mihalik

Patent number: 9597141Abstract: A method includes providing a bipolar energy source, a monopolar energy source, a bipolar assembly, and a monopolar assembly. The method further includes moving the monopolar assembly to a retracted position. Moving the monopolar assembly to the retracted position couples the bipolar energy source to the bipolar assembly and decouples the monopolar energy source from the monopolar assembly. The method further includes moving the monopolar assembly to a deployed position. Moving the monopolar assembly to the deployed position decouples the bipolar energy source from the bipolar assembly and couples the monopolar energy source to the monopolar assembly.Type: GrantFiled: May 19, 2014Date of Patent: March 21, 2017Assignee: COVIDIEN LPInventors: David M. Garrison, Dylan R. Kingsley, Tony Moua
