Patent number: 12161384Abstract: Apparatus and associated methods relate to controlling electrical power of an electrotherapeutic signal that is provided to a biological tissue engaged by an electrosurgical instrument during a medical procedure. Electrical power—a product of a voltage difference across and an electrical current conducted by the engaged biological tissue—is controlled according to a therapeutic schedule. The electrotherapeutic schedule can be reduced or terminated in response to a termination criterion being met. In some examples, the termination criterion is a current characteristic, such as, for example, a decrease in current conducted by the engaged biological tissue. In some examples, the termination criterion is a biological tissue resistance characteristic, such as, for example, an increase in the biological tissue resistance that exceeds a predetermined delta resistance value.Type: GrantFiled: September 18, 2023Date of Patent: December 10, 2024Assignee: Gyrus ACMI, Inc.Inventors: Kester Julian Batchelor, Riyad Moe, Wayne Williams

Patent number: 12090086Abstract: Systems and methods for manipulating the temperature of a surface are described. Described embodiments include thermal adjustment devices that may include a heatsink and that are operated in two or more modes of operation to apply a desired temperature to a user. In one operating mode the thermal adjustment device may apply a first temperature to an underlying surface while generating heat at a rate faster than the heatsink's heat dissipation rate. The thermal adjustment device may then apply a second temperature to reduce the rate of heat generation to be less than the heatsink's heat dissipation rate. These modes of operation may be applied cyclically to permit continuous operation of the thermal adjustment device. In some embodiments, the temperature profile applied when changing between the modes of operation may be selected such that the user experiences either a reduced, or substantially, neutral thermal sensation.Type: GrantFiled: January 11, 2019Date of Patent: September 17, 2024Assignee: EMBR Labs IP LLCInventors: Matthew J.
