The electrical pulses are controlled within ranges for voltage, wattage and duration of application. Multiple pulses or groups of pulses may be applied to obtain a desired result while maintaining any temperature increase below a level which destroys cells.Type: ApplicationFiled: December 3, 2018Publication date: April 4, 2019Inventors: BORIS RUBINSKY, CHARLOTTE DANIELS

Publication number: 20190099215Abstract: An electrosurgical cutting tool comprising a pair of pivotable blades that are mechanically operable as scissors or pliers. The blades have electrodes capable of delivery RF and/or microwave energy to cut or coagulate tissue between them. The tool combines the actuation and energy delivery mechanisms in a compact arrangement that enables the tool to be inserted through an instrument channel of a surgical scoping device, such as an endoscope, gastroscope or laparoscope. Each blade may comprise a planar body made of dielectric material that separates a first conductive element from a second conductive element. The blades may rotate relative to each other in the plane of the blades.Type: ApplicationFiled: May 16, 2017Publication date: April 4, 2019Inventors: Christopher Paul HANCOCK, Louis TURNER, Malcolm WHITE, Sandra May SWAIN, Patrick BURN, Steven MORRIS

Publication number: 20190099216Abstract: An electrosurgical instrument includes a needle configured as a first electrode and a coil extending through the needle and configured as a second electrode. The coil movable relative to the needle, and as the needle and the coil are inserted into tissue and energized with an electrical energy source, the needle and the coil apply current to the tissue to coagulate the tissue.Type: ApplicationFiled: February 22, 2017Publication date: April 4, 2019Inventors: Brandon J. Shuman, Peter Lambe, Chenhao Fu, Zoie R. Engman, Cassandra A. Saleira

Publication number: 20190099217Abstract: An end effector of an electrosurgical device may include a first body, a first electrode on the left side of the first body, and a second electrode on the right side of the first body. The first and second electrodes may be configured to receive electrosurgical energy to treat tissue in a target treatment zone. The end effector may also include a fluid aspiration port in fluid communication with a fluid path. The fluid aspiration port may be configured to remove a material from the target treatment zone.Type: ApplicationFiled: September 29, 2017Publication date: April 4, 2019Inventors: David A. Witt, David C. Yates, Frederick E. Shelton, IV, Cory G. Kimball, Barry C. Worrell, Monica L. Rivard, Scott R. Bingham

Publication number: 20190099218Abstract: An isolating circuit for electrosurgical generator arranged to produce radiofrequency (RF) energy and microwave energy for treating biological tissue. The generator has an RF channel and a microwave channel which are combined at signal combiner to enable the RF energy and microwave energy to be delivered into tissue along a common feed path. The isolating circuit comprises a tunable waveguide isolator at a junction between the microwave channel and signal combiner, and can include a capacitive structure between a ground conductor of the signal combiner and a conductive input section of the waveguide isolator to inhibit coupling of the RF energy and leakage of the microwave energy. The isolating circuit can combine into a single tunable unit all the necessary components to isolate the microwave and RF channels from one another whilst providing a high withstanding voltage.Type: ApplicationFiled: November 13, 2018Publication date: April 4, 2019Inventors: Christopher Paul HANCOCK, Malcolm WHITE, Nuwan DHARMISIRI

Publication number: 20190099219Abstract: A shaft assembly for a microwave ablation applicator which includes a shaft assembly and an antenna assembly located within the shaft assembly is disclosed. The shaft assembly comprises an elongate shaft (22) which extends from a first end to a second end thereof, and which defines therein a hollow inner volume and a longitudinal axis of the antenna assembly; and an applicator tip (24) mounted on the second end of the elongate body. The elongate shaft (22) comprises a first shaft portion (44) which extends longitudinally from the first end of the shaft (22) to an engagement region between the first and second ends of the shaft (22), and a second portion (46) which extends longitudinally from the engagement region to the second end of the shaft (22). The first shaft portion (44) is of a carbon reinforced plastics material, and the second shaft portion (46) is of a fibre reinforced plastics material having fibres which are non-electrically conductive.Type: ApplicationFiled: January 12, 2018Publication date: April 4, 2019Inventors: Tudor Thomas, David Nicholas Williams, Lewis Jones

Publication number: 20190099221Abstract: Disclosed are systems and methods for rapid generation of simulations of a patient's spinal morphology that enable pre-operative viewing of a patient's condition and to assist surgeons in determining the best corrective procedure and with any of the selection, augmentation or manufacture of spinal devices based on the patient specific simulated condition. The simulation is generated by morphing a generic spine model with a three-dimensional curve representation of the patient's particular spinal morphology derived from existing images of the patient's condition.Type: ApplicationFiled: July 12, 2018Publication date: April 4, 2019Inventors: John Schmidt, Margaret Redford, Jennifer McCool, Anthony Young, Noah Q.

Publication number: 20190099222Abstract: This invention concerns an automated registration method and device for a surgical robot enabling registration between a first three-dimensional location system comprising an optical distance sensor and a second three-dimensional location system comprising optical acquisition means. The method comprises: a first step of intraoperative registration between the first location system and data recorded on an anatomical surface of a patient and; a second step of intraoperative registration of two three-dimensional location systems. The second registration step is performed at the same time as the first registration step by detection, by the optical acquisition means, of at least one point of a point cloud acquired by the optical sensor during the first intraoperative registration.Type: ApplicationFiled: March 21, 2017Publication date: April 4, 2019Inventors: Bertin Nahum, Lucien Blondel, Pierre Maillet
