Publication number: 20240000493Abstract: Medical instruments and systems for applying energy to tissue, and more particularly relates to a system for ablating thin layers of the wall of a lumen in a patient's gastrointestinal tract such as a small intestine to cause an intended therapeutic effect. Devices perform the treatment by contacting targeted tissue with a vapor phase media wherein a subsequent vapor-to-liquid phase change of the media applies thermal energy to the tissue.Type: ApplicationFiled: June 28, 2023Publication date: January 4, 2024Inventor: John H.

Publication number: 20240000494Abstract: Electrosurgical generator and method for outputting a high-frequency alternating voltage to an electrosurgical instrument, including an inverter that generates a high-frequency alternating voltage having variable frequency and amplitude which is fed to an output socket for the electrosurgical instrument. Ahe inverter is a multi-level inverter controlled by a reference signal defining shape of the generated HF alternating voltage, the reference signal being defined by a datagram including a finite series of sequenced amplitude and frequency data vectors for a defined number of periods. By such datagrams including descriptive data for the desired HF sinusoidal curve, data amount and bandwidth required can be reduced. Thereby a variety of modes can be described using a minimum of data which can be as low as just a few dozen bytes long. This allows for efficient control even of complex modes.Type: ApplicationFiled: June 28, 2023Publication date: January 4, 2024Applicant: OLYMPUS WINTER & IBE GMBHInventors: Fabian JANICH, Jelle DIJKSTRA, Raphael BEHRENDT

Publication number: 20240000495Abstract: 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: ApplicationFiled: June 21, 2023Publication date: January 4, 2024Inventors: Kester Julian Batchelor, Maureen Julian Batchelor, Wayne Williams

Publication number: 20240000499Abstract: An apparatus includes a shaft assembly and an end effector, which includes first and second jaws pivotably coupled together. The first jaw includes a first electrode, and the second jaw includes a second electrode. The jaws may be used to clamp a portion of patient tissue and apply a non-therapeutic, or low voltage, radio frequency (RF) signal to the tissue. Based on the measured response of the current and voltage passing through the tissue, the apparatus can determine various characteristics of the clamped tissue, such as whether the tissue comprises body fluids, blood vessels, tendons, intestines, and/or fat. Once it is determined that the clamped tissue is the correct tissue type, the apparatus may then apply a therapeutic RF signal (e.g., a signal capable of sealing or cauterizing the tissue).Type: ApplicationFiled: June 30, 2022Publication date: January 4, 2024Inventors: Eric B.
