Publication number: 20220280782Abstract: The invention, in one aspect, relates to an intravascular electrode system. The system comprises one or more electrodes supported on an elongated resiliently flexible support member, and the support member may be used to introduce the electrodes into a blood vessel. As the support member is introduced into the blood vessel the support member bends to follow the path of the blood vessel.Type: ApplicationFiled: May 12, 2022Publication date: September 8, 2022Applicant: Lungpacer Medical Inc.Inventors: Joaquin Andres HOFFER, Marc-Andre NOLETTE, Viral THAKKAR, Bao Dung TRAN

Publication number: 20220212013Abstract: 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: ApplicationFiled: March 23, 2022Publication date: July 7, 2022Applicant: Lungpacer Medical Inc.Inventors: Joaquin Andres HOFFER, Gautam SADARANGANI, Marc-Andre NOLETTE, Viral THAKKAR, Bao Dung TRAN

Patent number: 10578325Abstract: The humidifier has an upper tank and a lower reservoir. A liquid level switch in the lower reservoir works in conjunction with a valve in a water passage between the upper tank and the lower reservoir in order to provide an automated flow of water to the lower reservoir during operation of the humidifier. The upper tank is unsealed, such that air in the upper tank may equalize with an ambient air pressure. The humidifier can be top-filled allowing that the upper tank to be permanently affixed to the base of the humidifier.Type: GrantFiled: November 24, 2015Date of Patent: March 3, 2020Assignee: Great Innovations, LLCInventors: Joseph A.

Patent number: 9645377Abstract: A compressive imaging system includes an illumination system arranged to illuminate an object of interest with illumination light, and a detection system configured to detect at least a portion of the illumination light after being at least one of reflected from, scattered from, or transmitted through the object of interest or to detect fluorescent light from the object of interest and to provide an imaging signal. The compressive imaging system further includes an image processing system configured to communicate with the detection system to receive the imaging signal. The illumination light from the illumination system comprises a plurality of light pulses such that each light pulse has a preselected spectrum that is distinguishable from spectra of all other pulses. The image processing system is configured to form an image of the object of interest using information concerning the preselected spectra of the plurality of light pulses.Type: GrantFiled: February 8, 2016Date of Patent: May 9, 2017Assignee: THE JOHNS HOPKINS UNIVERSITYInventors: Bryan T.
