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. Hatlestad, Gerard M. Carlson, Yousufali Dalal, Marina V. Brockway, Kent Lee, Richard O. Kuenzler, Carlos Haro, Krzysztof Z. Siejko, Abhilash Patangay

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.

Publication number: 20080119749Abstract: Respiration-synchronized heart sound trends can be detected using an implantable medical device, including a respiration sensor, a respiration phase detector, a heart sound sensor, a heart sound detector, and a processor. The implantable medical device can also include a cardiac sensor. The respiration-synchronized heart sound trends can include heart sounds occurring during specific phases of a respiration signal, such as inspiration or expiration. The heart sound signal can be gated or the heart sound sensor can be enabled or disabled using the cardiac sensor or the respiration sensor. Further, the heart sound trends can be displayed using an external display, and can provide information about a cardiovascular status using an analysis module, or the analysis module and a blood volume sensor.Type: ApplicationFiled: November 20, 2006Publication date: May 22, 2008Applicant: Cardiac Pacemakers, Inc.Inventors: Carlos Haro, Yi Zhang, Abhilash Patangay, Gerrard M.
