Publication number: 20220134095Abstract: This disclosure describes methods and systems for stimulating a respiratory muscle of a patient. The methods herein may include positioning a stimulator adjacent a nerve capable of activating the respiratory muscle; activating the stimulator to cause the respiratory muscle to contract; and ceasing the activation of the stimulator for a period of time. The level and the time of the stimulation may be adjusted for various applications. One or more of the steps in the methods may be repeated. The systems herein may include a stimulator for positioning adjacent a nerve capable of activating the respiratory muscle; a signal generator for providing stimulation energy to the stimulator; a sensor for detecting a response of the respiratory muscle to the stimulation energy; and a controller programmed to control the signal generator for providing stimulation with desired level and time.Type: ApplicationFiled: September 14, 2021Publication date: May 5, 2022Applicant: Lungpacer Medical Inc.Inventors: Viral S.

Patent number: 11311730Abstract: This disclosure describes, among other embodiments, systems and related methods for selecting electrode combinations to be used during nerve pacing procedures. A first set of electrode combinations of a nerve pacing system, such as a phrenic nerve pacing system for diaphragm activation, may be mapped (or tested) to determine the location of the electrode combinations relative to a target nerve. Once the general location of the target nerve is known, a more localized second set of electrode combinations may be tested to determine the most suitable electrode combinations for nerve stimulation. At various stages of the mapping process, electrode combinations that are non-optimal may be discarded as candidates for use in a nerve pacing procedure. The systems and methods described herein may allow for the selection of electrode combinations that are most suitable for stimulation of the left and right phrenic nerves during diaphragm pacing.Type: GrantFiled: July 12, 2019Date of Patent: April 26, 2022Assignee: Lungpacer Medical Inc.Inventors: Joaquin Andres Hoffer, Gautam Sadarangani, Marc-Andre Nolette, Viral S.
