Patent number: 9456856Abstract: An intrabody implant disclosed and methods of use are disclosed. The implant has an inclined surface, forming a wedge shape having an acute angle adapted to be placed between at least 2 separated portions of a single bony structure (such as a vertebral body). In some embodiments, the implant may be used to support portions of a vertebral body that have been separated surgically as part of a pedicle subtraction osteotomy and to orient the portions at a more predictable lordotic angle.Type: GrantFiled: September 26, 2013Date of Patent: October 4, 2016Assignee: Warsaw Orthopedic, Inc.Inventor: Rodney Ballard

Patent number: 9456857Abstract: The present invention relates to an apparatus for the strictly limited flexible stabilization of long bone fractures, said apparatus incorporating a stabilization element configured to be a helical rod that may be introduced into the cavity of a long bone and that comprises a fixation device at one end at least. In accordance with the invention there is provided that the helical rod comprises, beside a very high vertical spring rate, a bending spring rate that is reduced to the “physiological” level as compared to a marrow nail so that, once placed in the bone, minimal healing-promoting movements are being stimulated. It is further preferred that the helical rod has a normalized, uniformly configured head that is independent of the variable outer diameter of the helical rod, which is adapted to the respective bone.Type: GrantFiled: April 2, 2009Date of Patent: October 4, 2016Assignee: H&R SPECIAL SPRINGS L.P.Inventor: Reiner Labitzke

Patent number: 9456859Abstract: A polyaxial pedicle screw includes a threaded shaft portion for anchoring the pedicle screw in a vertebra, the pedicle screw having one axial end provided with a shaft head which is coupled to a mounting sleeve for a longitudinal beam in a rotatable and/or pivotable manner, including a fixing device for the selective positional fixation of the mounting sleeve with respect to the shaft portion. The fixing device includes a locking element as well as a counterforce part which is formed so as to be separate from the pedicle screw and counteracts the holding force of the locking element, preferably a grub screw or threaded nut, and is designed and/or retained in such a manner that the holding force of the locking element can be selectively released by means of the counterforce part, viz. is without any effect.Type: GrantFiled: August 2, 2012Date of Patent: October 4, 2016Assignee: Aesculap AGInventor: Andrea Peukert

Patent number: 9456861Abstract: A dispensing assembly includes a syringe body having a barrel and a dispensing tip. The dispensing assembly further includes a mixing and plunging assembly configured for coupling with the syringe body and comprising a mixer and a plunger. The mixer is configured for mixing material in the barrel and has a rod and a mixing element removably connected with the rod. The plunger is configured to dispense material from the barrel through the dispensing tip. Also, the rod is configured to be detached from the mixing element and used to push material out of the dispensing tip.Type: GrantFiled: June 23, 2014Date of Patent: October 4, 2016Assignee: Nordson CorporationInventors: Benjamin B. Anderson, Kevin C. Geppert, Jon E. Hoogenakker, Huadong Lou, Zachary Rzeszutek, Mark Stevenson

Patent number: 9456862Abstract: An electrosurgical generator includes an electrosurgical energy output configured to deliver electrosurgical energy to a bipolar end effector assembly in a conductive fluid environment for treating tissue. A controller having a processor is configured to control a waveform of the electrosurgical energy such that the waveform oscillates between a cut phase for initiating and sustaining tissue cutting, wherein the waveform includes a cut energy greater than the energy needed to create and sustain arcing, and a hemostasis phase, for desiccating/coagulating tissue, wherein the waveform includes a hemostasis energy less than the energy needed to sustain arcing.Type: GrantFiled: December 10, 2013Date of Patent: October 4, 2016Assignee: COVIDIEN LPInventors: Arlen K. Ward, Joe D. Sartor, Robert H. Wham

Patent number: 9456863Abstract: A surgical instrument includes a housing and an elongated shaft operably coupled to an actuating mechanism moveable between an actuated position and an unactuated position. An end effector includes a pair of opposing first and second jaw members and is adapted to connect to a source of electrosurgical energy. A switch is moveable between an activated position to initiate delivery of electrosurgical energy to the end effector and a deactivated position to terminate delivery of electrosurgical energy to the end effector. A switch activation member is configured to move the switch between an activated position and a deactivated position. A switch control member is configured to maintain the switch in the activated position during at least partial movement of the actuating mechanism from the actuated position to the unactuated position.Type: GrantFiled: December 13, 2013Date of Patent: October 4, 2016Assignee: COVIDIEN LPInventor: Tony Moua

Patent number: 9456864Abstract: An end effector for use with a surgical instrument is disclosed. The end effector comprises a first jaw, a second jaw, wherein the first jaw is movable relative to the second jaw to transition the end effector between an open configuration and an approximated configuration to clamp tissue between the first jaw and the second jaw, and a camming assembly. The camming assembly comprises a first camming member comprising a first distal camming portion, a first proximal camming portion, and a first flexible portion extending between the first distal camming portion and the first proximal camming portion. The camming assembly further comprises a second camming member and a connector at least partially disposed between the first camming member and the second camming member, wherein the camming assembly is movable relative to the end effector to transition the end effector to the approximated configuration.Type: GrantFiled: February 3, 2014Date of Patent: October 4, 2016Assignee: Ethicon Endo-Surgery, LLCInventors: David A.
