Patent number: 11864786Abstract: Systems, devices, and methods are operable to track usage of a surgical instrument and modify the performance of the surgical instrument based on the prior usage of the surgical instrument. Some surgical instruments are designed to have a limited service life beginning at their first use, or a limit to their overall usage in order to ensure safe use of the sensitive instruments. However, a lack of ability to track usage characteristics when the instrument is separated from an external power supply allows for user abuse and avoidance of such safety mechanisms. Adding a battery or capacitor to the instrument may allow for an ability to track usage when the instrument is separated from an external power supply. Implementing special user prompts, device use ratios, and device use half-life upon powering down of an instrument may additionally be used to prevent circumvention of safety features.Type: GrantFiled: February 26, 2020Date of Patent: January 9, 2024Assignee: Cilag GmbH InternationalInventors: Craig N.

Patent number: 11864809Abstract: Ablation catheters and systems include flexible catheter tips with a distal needle or ports for delivery of an ablative agent to a target tissue. Pressure monitoring during ablation ensure operation is performed within safe limits and with desired efficacy. Positioning elements help maintain the devices in the proper position with respect to the target tissue and also prevent the passage of ablative agent to normal tissues.Type: GrantFiled: January 14, 2022Date of Patent: January 9, 2024Assignee: Santa Anna Tech LLCInventor: Virender K. Sharma

Patent number: 11864810Abstract: A vapor delivery system and method is provided that is adapted for ablating bladder tissue to treat overactive bladder (OAB). The vapor delivery system includes an anchor tip configured anchor the system in the bladder while condensable vapor is delivered to target tissue. In one method, the vapor delivery system is advanced transurethrally into the patient to access the target tissue of the bladder, which can include a surface sensor of the bladder responsible for creating an urge incontinence sensation. The vapor delivery system includes a vapor source that provides a high quality vapor for delivery to tissue.Type: GrantFiled: January 6, 2022Date of Patent: January 9, 2024Assignee: Boston Scientific Scimed, Inc.Inventors: Michael Hoey, Maximillian D.

Patent number: 11864811Abstract: A method for performing cold atmospheric plasma therapy to treat breast cancer. The cancerous tumor is sampled and cold atmospheric plasma treatment is performed on sampled cancerous tumor cells ex vivo. The results of the testing are stored in an electronic storage media. A cell viability reduction rate of said tested samples is calculated with a processor and stored in memory. An average cell viability reduction rate is then calculated by the processor for the cancerous tumor. Cold atmospheric plasma dosages to be used in treatment of the cancerous tumor in vivo are then projected using the processor. The tumor is surgically removed from the patient. The surgical margins of the tumor are then treated with cold atmospheric plasma at the projected dosages.Type: GrantFiled: August 22, 2019Date of Patent: January 9, 2024Assignee: US Patent Innovations, LLCInventors: Xiaoqian Cheng, Jerome Canady, Warren J Rowe

Patent number: 11864812Abstract: Systems and methods for enhancing surgical outcomes by providing generators having optimal RF output for sealing, fusing and/or cutting tissue or vessels under all dynamic conditions are described. Examples of dynamic conditions may include varying tissue impedance load due to electrosurgical operations or tissue affects, any operational conditions and commands determined by the surgeon, surgical procedure and/or device script. This is achieved by implementing a digital closed-loop control system within the electrosurgical generator to regulate voltage, current, and power of the RF output. The digital closed-loop control system may include an RF amplifier for generating RF energy, a feedback system for constantly monitoring the electrical characteristics, e.g.Type: GrantFiled: September 5, 2019Date of Patent: January 9, 2024Assignee: Applied Medical Resources CorporationInventors: Michael Nguyen, Igor Gorin, Joanna Pang

Patent number: 11864813Abstract: 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: May 14, 2020Date of Patent: January 9, 2024Assignee: Gyrus ACMI, Inc.Inventors: Kester Julian Batchelor, Riyad Moe, Wayne Williams

Patent number: 11864815Abstract: An electrosurgical device for cutting tissue includes a body portion and a tool portion extending distally from the body portion. The tool portion defines a longitudinal axis. The tool portion includes a return lead adapted to be electrically coupled to a return terminal of an electrosurgical energy source, first and second electrical insulators disposed on a first surface of the return lead, and an active lead adapted to be electrically coupled to an active terminal of the electrosurgical energy source. The first electrical insulator is disposed distal of the second electrical insulator. The active lead extends through the first and second electrical insulators such that the active lead and the first surface of the return lead define a gap therebetween. Upon activation of the electrosurgical energy source, electrosurgical energy is transmitted from the active lead through tissue to the return lead to cut the tissue.Type: GrantFiled: February 6, 2020Date of Patent: January 9, 2024Assignee: Covidien LPInventors: Jacob C.
