Publication number: 20230264031Abstract: Devices, systems, and methods for pacing tissue are disclosed herein. In some embodiments, the devices, systems, and methods position a tip section of a catheter adjacent tissue within an anatomical structure. The tip section is attached to a distal end portion of a catheter shaft, has a maximum radial dimension that is larger than a maximum radial dimension of the catheter shaft, and includes a plurality of electrodes spatially distributed about the tip section. The devices, systems, and methods further select one or more groupings of individual ones of the plurality of electrodes and deliver stimulating energy to or through the adjacent tissue via the selected groupings of electrodes. The stimulating energy is sufficient to activate nerve tissue proximate the tip section but is insufficient to ablate the adjacent tissue. In this manner, devices, systems, and methods disclosed herein can be used to locate nerve tissue proximate the tip section.Type: ApplicationFiled: August 6, 2021Publication date: August 24, 2023Inventors: Doron Harlev, Paul B. Hultz, Robert Alan Mest

Publication number: 20230157751Abstract: Devices, systems, and methods for treating cardiac arrhythmia are disclosed herein. In some embodiments, devices, systems, and methods disclosed herein deliver interrogating energy to tissue at a position on a wall of an anatomical structure of a patient. If the devices, systems, and methods disclosed herein detect a change in electrical activity of the anatomical structure in response to the interrogating energy, the devices, systems, and methods disclosed herein can apply irreversible therapy to the tissue. In some embodiments, the change in electrical activity corresponds to slowing or termination of a detected arrhythmia.Type: ApplicationFiled: December 2, 2022Publication date: May 25, 2023Inventors: Doron Harlev, Paul B. Hultz

Publication number: 20230157748Abstract: Devices, systems, and methods of the present disclosure are directed to controlling distribution of electrical energy moving from an ablation electrode at a treatment site within a patient to a plurality of return electrodes on skin of the patient. Control over the distribution of electrical energy moving from the ablation electrode to the plurality of return electrodes can reduce or eliminate the need for manual intervention (e.g., repositioning the plurality of return electrodes on the skin of the patient, repositioning the patient, etc.) to achieve a suitable distribution of the electrical energy. Additionally, or alternatively, the devices, systems, and methods of the present disclosure can respond rapidly and automatically to changes in distribution of the electrical energy to reduce the likelihood and magnitude of inadvertent changes in the distribution of electrical energy over the course of a medical procedure.Type: ApplicationFiled: September 27, 2022Publication date: May 25, 2023Inventors: Doron Harlev, Ilya Bystryak, Alexander Shrabstein, Yanko K.

Publication number: 20200360079Abstract: Devices, systems, and methods of the present disclosure are directed to selectively controlling delivery of electrical energy to an ablation electrode, with the selective control based on a history of the electrical energy delivered to a return electrode (e.g., electrical energy delivered in a current time-step and in one or more time-steps preceding the current time-step). Controlling electrical energy delivered to an ablation electrode based on the history of electrical energy delivered to a return electrode can reduce the likelihood of unintended tissue damage away from a treatment site as electrical energy is delivered to the treatment site via the ablation electrode. Further, or instead, the devices, systems, and methods of the present disclosure can reduce the likelihood of unintended tissue damage away from the treatment site while reducing or eliminating the need to interrupt lesion formation by the ablation electrode.Type: ApplicationFiled: November 26, 2018Publication date: November 19, 2020Inventors: Doron Harlev, Paul B. Hultz, Robert Alan Mest

Publication number: 20200196885Abstract: Devices, systems, and methods directed to detecting positions of a catheter relative to cardiac regions of a patient are disclosed herein. In some implementations, an ablation system can include a cardiac catheter and a catheter interface unit in communication with one or more electrodes and/or sensors on the cardiac catheter. The devices, systems, and methods of the present disclosure can identify regions of the heart based on one or more signals from the respective one or more electrodes and/or sensors. In these and other implementations, the devices, system, and methods can display visual indicia based on an identified cardiac region.Type: ApplicationFiled: August 29, 2018Publication date: June 25, 2020Inventors: Doron Harlev, Paul B.

Patent number: 9078077Abstract: An approach to forming output signals both permits flexible and temporally and/or frequency local processing of input signals while limiting or mitigating artifacts in such output signals. Generally, the approach involves first synthesizing prototype signals for the output signals, or equivalently characterizing such prototypes, for example, according to their statistical characteristics, and then forming the output signals as estimates of the prototype signals, for example, as weighted combinations of the input signals.Type: GrantFiled: October 21, 2011Date of Patent: July 7, 2015Assignee: Bose CorporationInventors: Paul B.

Patent number: 8724827Abstract: An audio system for a vehicle has at least one source of audio signals. At least one array of speaker elements is located at each seat position that radiates within a range of bass frequencies. For each at least one array, the speaker elements receive a common audio signal, and a respective filter is disposed between the common audio signal and each of the speaker elements. Each respective filter processes magnitude and phase of the common audio signal independently of each other respective filter to thereby define a directional audio radiation from the at least one array.Type: GrantFiled: July 19, 2007Date of Patent: May 13, 2014Assignee: Bose CorporationInventors: Klaus Hartung, Paul B.
