Patent number: 9242105Abstract: Described herein are methods and devices that utilize electrical neural stimulation to treat heart failure by modulating a patient's autonomic balance in a manner that inhibits sympathetic activity and/or augments parasympathetic activity. Because other therapies for treating heart failure may also affect a patient's autonomic balance, a device for delivering neural stimulation is configured to appropriately titrate such therapy in either an open-loop or closed-loop fashion.Type: GrantFiled: May 2, 2014Date of Patent: January 26, 2016Assignee: Cardiac Pacemakers, Inc.Inventors: Marina V.

Publication number: 20150039043Abstract: Cardiac systems and methods using ECG and blood information for arrhythmia detection and discrimination. Detection circuitry is configured to produce an ECG. An implantable blood sensor configured to produce a blood sensor signal is coupled to a processor. The processor is coupled to the detection and energy delivery circuitry, and used to evaluate and treat cardiac rhythms using both the cardiac electrophysiologic and blood sensor signals. The blood sensor is configured for subcutaneous non-intrathoracic placement and provided in or on the housing, on a lead coupled to the housing, and/or separate to the housing and coupled to the processor via hardwire or wireless link. The blood sensor may be configured for optical sensing, using a blood oxygen saturation sensor or pulse oximeter. A cardiac rhythm may be evaluated using the electrocardiogram signal and the blood sensor signal, and tachyarrhythmias may be treated after confirmation using the blood sense signal.Type: ApplicationFiled: August 13, 2014Publication date: February 5, 2015Inventors: Apurv Kamath, Paul A.

Patent number: 8845544Abstract: An implantable device and method for monitoring S1 heart sounds with a remotely located accelerometer. The device includes a transducer that converts heart sounds into an electrical signal. A control circuit is coupled to the transducer. The control circuit is configured to receive the electrical signal, identify an S1 heart sound, and to convert the S1 heart sound into electrical information. The control circuit also generates morphological data from the electrical information. The morphological data relates to a hemodynamic metric, such as left ventricular contractility. A housing may enclose the control circuit. The housing defines a volume coextensive with an outer surface of the housing. The transducer is in or on the volume defined by the housing.Type: GrantFiled: September 11, 2013Date of Patent: September 30, 2014Assignee: Cardiac Pacemakers, Inc.Inventors: Gerrard M.

Patent number: 8805493Abstract: The health state of a subject is automatically evaluated or predicted using at least one implantable device. In varying examples, the health state is determined by sensing or receiving information about at least one physiological process having a circadian rhythm whose presence, absence, or baseline change is associated with impending disease, and comparing such rhythm to baseline circadian rhythm prediction criteria. Other chronobiological rhythms beside circadian may also be used. The baseline prediction criteria may be derived using one or more past physiological process observation of the subject or population of subjects in a non-disease health state. The prediction processing may be performed by the at least one implantable device or by an external device in communication with the implantable device. Systems and methods for invoking a therapy in response to the health state, such as to prevent or minimize the consequences of predicted impending heart failure, are also discussed.Type: GrantFiled: March 19, 2013Date of Patent: August 12, 2014Assignee: Cardiac Pacemakers, Inc.Inventors: Yi Zhang, John D.

Patent number: 8758260Abstract: A system comprising an implantable medical device (IMD) includes an implantable heart sound sensor to produce an electrical signal representative of at least one heart sound. The heart sound is associated with mechanical activity of a patient's heart. Additionally, the IMD includes a heart sound sensor interface circuit coupled to the heart sound sensor to produce a heart sound signal, and a signal analyzer circuit coupled to the heart sound sensor interface circuit. The signal analyzer circuit measures a baseline heart sound signal, and deems that an ischemic event has occurred using, among other things, a measured subsequent change in the heart sound signal from the established baseline heart sound signal.Type: GrantFiled: September 13, 2011Date of Patent: June 24, 2014Assignee: Cardiac Pacemakers, Inc.Inventors: Yi Zhang, Richard Fogoros, Carlos Haro, Yousufali Dalal, Marina V.

Patent number: 8630716Abstract: A method embodiment comprises generating a neural stimulation signal for a neural stimulation therapy. The signal is generated during a duty cycle of a stimulation period to provide the neural stimulation therapy with an intensity at a therapy level for a portion of the duty cycle. In various embodiments, a ramp up protocol is implemented to begin the duty cycle, a ramp down protocol is implemented to end the duty cycle, or both the ramp up protocol and the ramp down protocol are implemented. The ramp up protocol includes ramping up the intensity from a non-zero first subthreshold level for the neural stimulation therapy at the beginning of the duty cycle to the therapy level. The ramp down protocol includes ramping down the intensity from the therapy intensity level to a non-zero second subthreshold level for the neural stimulation therapy at the end of the duty cycle.Type: GrantFiled: August 16, 2012Date of Patent: January 14, 2014Assignee: Cardiac Pacemakers, Inc.Inventors: Marina V.
