Publication number: 20230310851Abstract: A catheter may include electrodes for transvascular nerve stimulation. The electrodes may be positioned within lumens of the catheter and aligned with apertures in the outer wall of the catheter. The electrodes may produce focused electrical fields for stimulation of one or more nerves. In one embodiment, the catheter may include a set of proximal electrodes and a set of distal electrodes, and the proximal electrodes may stimulate a patient’s left phrenic nerve and the distal electrodes may stimulate a patient’s right phrenic nerve.Type: ApplicationFiled: June 7, 2023Publication date: October 5, 2023Applicant: Lungpacer Medical Inc.Inventors: Viral THAKKAR, Joaquin Andres HOFFER, Bao Dung TRAN, Douglas G. EVANS, John NASH

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: 10293164Abstract: A catheter may include an outer layer defining a plurality of apertures therethrough, and a body defining at least one longitudinal lumen therein. The body may be within the outer layer, and the apertures may be radially outward of the lumen. The catheter may also include a plurality of electrodes positioned in or on the catheter, with each electrode being electrically exposed through an aperture of the plurality of apertures. A ribbon cable may extend through the lumen and include a plurality of leads, with the plurality of leads being electrically connected to the plurality of electrodes. The plurality of leads and electrodes may be formed by the deposition of conductive inks or paints, or by the electrodeposition of copper or other conductive metals or materials.Type: GrantFiled: May 26, 2017Date of Patent: May 21, 2019Assignee: Lungpacer Medical Inc.Inventors: John E.
