Publication number: 20230389869Abstract: A system includes a sheet flexible material having a contact surface adapted to be placed on an outer surface of a patient's body. A plurality of sensing apparatuses have respective sensing surfaces distributed across the contact surface of the sheet. One or more of the sensing apparatuses include a multimodal sensing apparatus. Each multimodal sensing apparatus includes a monolithic substrate carrying a transducer, circuitry and an electrophysiological sensor. The transducer is coupled to the circuitry and configured to at least sense acoustic energy from a transducer location of the sheet. The electrophysiological sensor is also coupled to the circuitry, and the sensor is configured to at least sense electrophysiological signals from a sensor location of the sheet, in which the sensor location has a known spatial position relative to the transducer location.Type: ApplicationFiled: May 9, 2023Publication date: December 7, 2023Inventors: Sarah E. AHLBERG, Randal C. SCHULHAUSER

Publication number: 20230355301Abstract: An example system for use in ablating target tissue includes memory configured to store anatomical and/or physiological information of a patient and processing circuitry communicatively coupled to the memory. The processing circuitry is configured to, based on the anatomical information and/or the physiological information, determine ablation parameters, the ablation parameters including a suggested positioning of at least energy delivery element of at least one catheter and/or an amount of energy to be delivered via the at least one energy delivery element to the target tissue during ablation. The processing circuitry is configured to output, for display, a representation of at least one of a suggested positioning of the at least one energy delivery element during the ablation, a representation of the target tissue, or a representation of the predicted tissue volume that will be ablated after delivery of ablation energy.Type: ApplicationFiled: April 11, 2023Publication date: November 9, 2023Inventors: Mary A. Beckman, Heather L. O'Connell, Timothy G. Laske, Mark T. Stewart, Brian T. Howard, Lars M. Mattison, Megan M. Schmidt, Sarah E. Ahlberg

Patent number: 11642173Abstract: Various embodiments of a system for guiding an instrument through a region of a patient are disclosed. The system includes an instrument and a controller that is adapted to receive ultrasound image data from an ultrasound sensor, receive EM tracking data from an EM tracking system, and identify a physiological landmark of the region of the patient based on the ultrasound image data. The controller is further adapted to determine at least one of a position, orientation, or trajectory of the instrument based on the EM tracking data and generate a graphical user interface showing at least one of the position, orientation, or trajectory of the instrument in relation to a plane of the ultrasound image data, and a target zone that is registered with the physiological landmark.Type: GrantFiled: June 6, 2019Date of Patent: May 9, 2023Assignee: MEDTRONIC, INC.Inventors: Elizabeth A. Schotzko, Linnea R. Lentz, Sarah E. Ahlberg, Syed Omar Ishrak
