Publication number: 20200147366Abstract: 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: November 7, 2019Publication date: May 14, 2020Applicant: Lungpacer Medical Inc.Inventors: Joaquin Andres HOFFER, Marc-Andre NOLETTE, Viral S.

Patent number: 10589097Abstract: Transvascular diaphragm pacing systems (TDPS) and methods are disclosed for providing respiratory therapy to a patient. The TDPS can provide rapid insertion and deployment of endovascular pacing electrodes in critically ill patients who require intubation and invasive PPMV in order to support the physiological requirements of the human ventilatory system. The systems and methods make best use of the contractile properties of the diaphragm muscle and prevent muscle disuse and muscle atrophy. This can be carried out by engaging the phrenic nerves using patterned functional electrical stimulation applied to endovascular electrodes that are temporarily and reversibly inserted in central veins of the patient, such as the left subclavian vein and the superior vena cava.Type: GrantFiled: July 2, 2019Date of Patent: March 17, 2020Assignee: Lungpacer Medical Inc.Inventors: Ramasamy Meyyappan, Joaquin Andres Hoffer, Marcelo Baru, Bernard Coquinco, Rodrigo Andres Sandoval, Jessica Kit-Sum Tang

Patent number: 10561844Abstract: Diaphragm pacing systems and methods are disclosed for providing respiratory therapy to a patient. The diaphragm pacing systems can provide rapid insertion and deployment of pacing electrodes in critically ill patients who require intubation and invasive Positive Pressure Mechanical Ventilation (PPMV) in order to support the physiological requirements of the human ventilatory system. The systems and methods make best use of the contractile properties of the diaphragm muscle and prevent muscle disuse and muscle atrophy. This can be carried out by engaging the phrenic nerves using patterned functional electrical stimulation. The diaphragm pacing systems can be designed to seamlessly interface with any commercially available positive-pressure ventilatory assistance/support equipment such as is commonly in use in hospital intensive care units (ICU) for treating critically ill patients with breathing insufficiencies, pain, trauma, sepsis or neurological diseases or deficits.Type: GrantFiled: August 27, 2018Date of Patent: February 18, 2020Assignee: Lungpacer Medical Inc.Inventors: Ramasamy Meyyappan, Joaquin Andres Hoffer, Marcelo Baru, Bernard Coquinco, Rodrigo Andres Sandoval, Jessica Kit-Sum Tang

Patent number: 10561843Abstract: Electrode structures for transvascular nerve stimulation combine electrodes with an electrically-insulating backing layer. The backing layer increases the electrical impedance of electrical paths through blood in a lumen of a blood vessel and consequently increases the flow of electrical current through surrounding tissues. The electrode structures may be applied to stimulate nerves such as the phrenic, vagus, trigeminal, obturator or other nerves.Type: GrantFiled: August 27, 2018Date of Patent: February 18, 2020Inventor: Joaquin Andres Hoffer

Publication number: 20190336773Abstract: 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: July 12, 2019Publication date: November 7, 2019Applicant: Lungpacer Medical Inc.Inventors: Joaquin Andres HOFFER, Gautam SADARANGANI, Marc-Andre NOLETTE, Viral S.
