Patent number: 11622784Abstract: Arthroscopic cutters are used for resecting tissues, such as meniscal tissues, in meniscectomies or other arthroscopic procedures. The arthroscopic cutters have a shaft assembly with openable-closeable jaws at a working end of the shaft. A handpiece having a motor drive may be detachably coupled to a hub on a hub end of the handpiece. When the shaft is coupled to the handpiece, the motor drive will couple to the jaw structure to open and close the jaw structure to cut meniscal and other tissues.Type: GrantFiled: February 13, 2020Date of Patent: April 11, 2023Assignee: Relign CorporationInventors: Aaron Germain, Jeffrey Norton, Salvatore G.

Publication number: 20220355019Abstract: A fluid management system includes a pump connectable to a fluid source. An inflow line removably connects to a cannula for delivering a fluid flow from the pump into a surgical site, such as a joint cavity. A flow pressure sensor is coupled to measure flow pressure in the inflow line and produce a measured pressure value, A controller is connected to the pump and the flow pressure sensor, and the controller maintains a pressure set point by controlling a pump speed based on a backpressure-adjusted pressure value calculated by subtracting a backpressure value selected from a backpressure table from the measured pressure value. The BAPV is monitored to determine whether the BAPV deviates outside an initial BAPV range, and corrective measure are taken should such deviations occur.Type: ApplicationFiled: July 22, 2022Publication date: November 10, 2022Inventors: Steffan Benamou, Michael D.

Publication number: 20210113262Abstract: An electrosurgical probe can be detachably secured to a handpiece having a motor drive unit and an RF current contact. The electrosurgical probe includes an elongate shaft having a longitudinal axis, a distal dielectric tip, and a proximal hub which is detachably securable to the handpiece. A hook electrode is reciprocatably mounted in the distal dielectric tip, and an RF connector on the hub is couplable to the RF current contact in the handpiece when the hub is secured to the handpiece. A drive mechanism in the hub mechanically couples to the hook electrode, and drive mechanism engages a rotational component in the motor drive unit when the hub is secured to the handpiece. The drive mechanism converts rotational motion from the rotational component into axial reciprocation and transmits the axial reciprocation to the hook electrode to axially displace the hook electrode between a non-extended position and an extended position relative to the dielectric tip.Type: ApplicationFiled: December 3, 2020Publication date: April 22, 2021Applicant: RELIGN CorporationInventors: Aaron Germain, Kyle Klein, Steffan Benamou, Jeffrey Norton, Jacob Tonkel

Publication number: 20200179033Abstract: An electrosurgical system includes an electrosurgical probe connected to a control console, wherein the probe is capable of coagulating and ablating tissue depending on a selected operating mode. Before operating the system, probe-specific data stored in a memory device associated with the probe is read by a processing device in the console. The data includes source impedance values specific to a coagulation or cutting mode of operation. A constant duty cycle value for a modulated cutting mode also is provided. Depending on the operating mode selected, an RF generator adjusted to have a predetermined source impedance value provides a voltage value to the probe. During the duty-cycled mode, the RF generator generates an instantaneous voltage value output for a duty cycle portion that is less than 100% of a time period, which value is no less than a maximum continuous average voltage value for the electrosurgical probe.Type: ApplicationFiled: February 19, 2020Publication date: June 11, 2020Inventors: Steffan A.
