Publication number: 20170172637Abstract: In a human or animal patient, two bone portions separated by a cut or fracture are stabilized in a desired position relative to each other by bringing the two bone portions into this desired position, by pulling them against each other, by providing an opening having a mouth on a bone surface and reaching across the cut or fracture and walls in both bone portions, by inserting an implant into the opening and anchoring the implant in the walls of the opening with the aid of a material having thermoplastic properties and energy transmitted into the implant for in situ liquefaction of at least part of the material having thermoplastic properties. One exemplary application of the stabilizing procedure concerns the two tibial bone portions separated by tibial plateau leveling osteotomy in a canine patient suffering from cranial cruciate ligament damage or rupture in a stifle joint.Type: ApplicationFiled: January 10, 2017Publication date: June 22, 2017Inventor: Jörg Mayer

Publication number: 20170172639Abstract: An orthopedic implant screw driver includes drive shaft. A first gear is operably coupled to the drive shaft and in meshing engagement with a hollow gear which rotates in response to rotation of the drive shaft. The hollow gear includes a passage defining an inwardly facing screw engagement periphery configured to receive and drivingly rotate a threaded portion of the screw. A method of securing an orthopedic implant to a bone includes positioning a screw within the passage which is configured to drivingly engage a threaded portion of the screw and rotating a drive shaft in driving engagement with the gear causing the gear to engage the screw along the threaded portion of the screw and rotatably drive the screw via the threaded portion.Type: ApplicationFiled: December 27, 2016Publication date: June 22, 2017Inventors: Anthony C. DeFalco, Rawley Stanhope, Daniel C. Taylor, Rui J. Ferreira

Publication number: 20170172640Abstract: A method of treating a lung tumor or metastasis comprising forming a condensable vapor comprising water and a therapeutic agent and delivering the vapor and therapeutic agent to a target tissue in a region of a patient's lung. The therapeutic agent may be chemotherapy drug. In embodiments, vapor ablation is combined with systemic therapy.Type: ApplicationFiled: December 13, 2016Publication date: June 22, 2017Inventor: Erik Henne

Publication number: 20170172641Abstract: A surgical instrument for thermally-mediated therapies in targeted tissue volumes and for causing thermal effects in polymer tissue-contacting members. In one embodiment, the instrument has a working end with an interior chamber that is supplied with a biocompatible liquid. An energy source causes a liquid-to-vapor phase change within the interior of the instrument. The vapor phase media then is ejected from the working surface of the instrument, and a controlled vapor-to-liquid phase change in an interface with tissue applies thermal energy substantially equal to the heat of vaporization to ablate tissue. The vapor-to-liquid phase transitions, or internal energy releases, can be provided about thin-film flexible structures for engaging body lumens and cavities. An exemplary embodiment can be used for shrinking, sealing, welding or creating lesions in tissue—while causing limited collateral thermal damage and while totally eliminating electrical current flow in the engaged tissue.Type: ApplicationFiled: March 1, 2017Publication date: June 22, 2017Applicant: Tsunami MedTech, LLCInventor: John H.

Publication number: 20170172642Abstract: Electrosurgical procedures. At least some of the example methods that include: supplying energy to an active electrode of an electrosurgical wand, the supplying energy to the active electrode by an electrosurgical controller; monitoring an electrical parameter associated with the energy; and determining, based on the electrical parameter, the presence of a wand condition of the electrosurgical wand, the wand condition being at least one selected from the group consisting of: a surface area of the active electrode is less than a predetermined threshold surface area; the surface area of the active electrode is approaching the predetermined threshold surface area; and that the electrosurgical wand is affected by a blockage.Type: ApplicationFiled: March 3, 2017Publication date: June 22, 2017Inventors: David Y.

Publication number: 20170172643Abstract: A grasping treatment unit includes a first jaw, and a second jaw openable and closable relative to the first jaw. In the first jaw, a heating wire continues without branching from a first extending end to a second extending end, and generates heat over an entire length from the first extending end to the second extending end when an electric current flows therethrough. A heating portion is lower in calorific value per unit area in a distal portion than in a proximal portion in the first jaw in a state where the heat is generated from the heating wire.Type: ApplicationFiled: March 1, 2017Publication date: June 22, 2017Applicant: OLYMPUS CORPORATIONInventors: Tomoyuki TAKASHINO, Yusuke TAKEI, Kazuhiro TANAKA

Publication number: 20170172644Abstract: The preferred embodiment provides apparatus for ablating a vessel by generating heat within a vessel to cause blood clotting to occlude the vessel. The apparatus includes an electrically resistive element at the distal end of the apparatus, the resistive element being uncoated and therefore in bare form. An alternating current supply feeds electrical current through the resistive element to cause heating of the element and surrounding blood or tissue. The alternating current power supply preferably is balanced about a centre point so as to create a net sum of alternating pulses of zero. It has been found that the supply of alternating current to the resistive element reduces or eliminates corrosion of the resistive element in blood as the resistive element is heated. Use of conductive coatings for a sacrificial anode can be avoided.Type: ApplicationFiled: December 15, 2016Publication date: June 22, 2017Inventors: Raimo Urban BUTZBACKER, Rune T. Paamand
