Patent number: 11944371Abstract: A bipolar electrosurgical device including an outer shaft, an inner shaft, first and second electrode surfaces, and an irrigation channel. The outer shaft defines a lumen, a proximal end and a distal end forming a cutting window. The inner shaft is rotatably disposed within the outer shaft, and defines a distal portion forming a cutting tip. The cutting tip and the cutting window combine to define a cutting implement. The first and second electrode surfaces are electrically isolated, and are formed at the cutting implement. The irrigation channel extends parallel to the outer shaft, and terminates in at least one outlet port. The outlet port is proximally spaced from the cutting window and is located radially outside of the outer shaft. Fluid (e.g., saline) is emitted at the exterior surface of the device near the cutting window and is readily present for interacting with the electrode surfaces.Type: GrantFiled: December 17, 2021Date of Patent: April 2, 2024Assignee: Medtronic Xomed, Inc.Inventors: John R Prisco, Eric P. Detmers, Wenjeng Li, David J. Little, Patrick Richart, Jose Valdez

Publication number: 20220096147Abstract: A bipolar electrosurgical device is disclosed that operates in a mechanical cutting mode and a hemostasis mode. The device includes a housing and a blade assembly extending from the housing. The blade assembly forms a cutting tip and cutting window at a distal end region to provide mechanical cutting of tissue and first and second electrode assemblies to provide electrical energy to tissue. The first electrode assembly includes an outer shaft defining a first electrode surface and the second electrode assembly includes an electrode body extending along and electrically isolated from an outer shaft and defining a U-shape in cross section.Type: ApplicationFiled: December 13, 2021Publication date: March 31, 2022Applicant: Medtronic Xomed, Inc.Inventors: John R.
