Patent number: 9333352Abstract: Methods and devices for reducing ventricle filling volume are disclosed. In some embodiments, an electrical stimulator may be used to stimulate a patient's heart to reduce ventricle filling volume or even blood pressure. When the heart is stimulated in a consistent way to reduce blood pressure, the cardiovascular system may over time adapt to the stimulation and revert back to the higher blood pressure. In some embodiments, the stimulation pattern may be configured to be inconsistent such that the adaptation response of the heart is reduced or even prevented. In some embodiments, an electrical stimulator may be used to stimulate a patient's heart to cause at least a portion of an atrial contraction to occur while the atrioventricular valve is closed. Such an atrial contraction may deposit less blood into the corresponding ventricle than when the atrioventricular valve is opened throughout an atrial contraction.Type: GrantFiled: March 10, 2015Date of Patent: May 10, 2016Assignee: BackBeat Medical, Inc.Inventors: Yuval Mika, Darren Sherman, Robert S. Schwartz, Robert A. Van Tassel, Daniel Burkhoff

Publication number: 20160022896Abstract: A system and methods of using a multi-lumen catheter and a blood pump to increase cardiac output and blood oxygenation are described. The system diverts deoxygenated blood from the right atrium to the left atrium, through the atrial septum. The catheter is adapted for simultaneously pumping blood to and from a patient's heart. A gas exchanger may be used as part of the system to remove CO2 and add o2 to the blood that is pumped via the system. Components or portions of the system may be implantable in the patient.Type: ApplicationFiled: July 22, 2015Publication date: January 28, 2016Inventor: Daniel Burkhoff

Publication number: 20150360035Abstract: Systems and methods for controlling blood pressure by controlling atrial pressure and atrial stretch are disclosed. In some embodiments, a stimulation circuit may be configured to deliver a stimulation pulse to at least one cardiac chamber of a heart of a patient, and at least one controller may be configured to execute delivery of one or more stimulation patterns of stimulation pulses to the at least one cardiac chamber, wherein at least one of the stimulation pulses stimulates the heart such that an atrial pressure resulting from atrial contraction of an atrium overlaps in time a passive pressure build-up of the atrium, such that an atrial pressure of the atrium resulting from the stimulation is a combination of the atrial pressure resulting from atrial contraction and the passive pressure build-up and is higher than an atrial pressure of the atrium would be without the stimulation, and such that the blood pressure of the patient is reduced.Type: ApplicationFiled: June 17, 2014Publication date: December 17, 2015Inventors: Yuval Mika, Darren Sherman, Robert S.
