Patent number: 10537287Abstract: Prosthetic heart devices may be implanted into the heart with a sensor coupled to the device, the sensor being configured to measure physiological data, such as blood pressure, in the heart. Devices that may employ such sensors include prosthetic heart valves and occlusion devices, although sensor systems may be deployed in the heart separate from other implantable devices. The sensors may include a body with different configurations for attaching to the implantable device, such as apertures for sutures or fingers for connecting to structures of the implantable device. The sensors may provide data that allow a determination of aortic regurgitation or other information indicative of function of the implantable device and patient health during and after implantation of the device.Type: GrantFiled: October 6, 2017Date of Patent: January 21, 2020Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Peter N.

Patent number: 9839781Abstract: A system to measure intracardiac impedance includes implantable electrodes and a medical device. The electrodes sense electrical signals of a heart of a subject. The medical device includes a cardiac signal sensing circuit coupled to the implantable electrodes, an impedance measurement circuit coupled to the same or different implantable electrodes, and a controller circuit coupled to the cardiac signal sensing circuit and the impedance measurement circuit. The cardiac signal sensing circuit provides a sensed cardiac signal. The impedance measurement circuit senses intracardiac impedance between the electrodes to obtain an intracardiac impedance signal. The controller circuit determines cardiac cycles of the subject using the sensed cardiac signal, and detects tachyarrhythmia using cardiac-cycle to cardiac-cycle changes in a plurality of intracardiac impedance parameters obtained from the intracardiac impedance signal.Type: GrantFiled: May 7, 2013Date of Patent: December 12, 2017Assignee: Cardiac Pacemakers, Inc.Inventors: Yunlong Zhang, James O.

Publication number: 20140207206Abstract: According to a system or method, information indicative of a cardiac depolarization signal can be obtained. Information indicative of an acoustic signal from an implantable acoustic sensor included as a portion of an implantable therapy device can be obtained. A feature indicative of an R wave can be identified from the information indicative of the cardiac depolarization signal, and a feature indicative of an S2 heart sound can be identified from the information indicative of the acoustic signal. A time interval between an instant corresponding to the feature indicative of the R wave and an instant corresponding to the feature indicative of the S2 heart sound can be determined. Using information about the determined time interval, an adjusted pacing therapy parameter can be provided for use in a pacing therapy to be provided by the implantable therapy device.Type: ApplicationFiled: March 25, 2014Publication date: July 24, 2014Applicant: Cardiac Pacemakers, Inc.Inventors: Abhilash Patangay, Krzysztof Z.

Publication number: 20130303931Abstract: Inhalation measurement systems and methods enable, during inhalant exposure, substantially real-time respiratory measurements of a test subject using techniques that obtain measurements of respiration directly from that test subject, instead of from inhalation chamber parameter measurements. Direct test subject respiratory measurements may be, by way of example only, impedance measurements. These respiratory measurements taken directly from the test subject may be transmitted, wirelessly for example, for processing during the course of the test to a processing system to determine a cumulative volume of inhalant inspired by the test subject. From that, a cumulative amount of inhalant (or dose) inspired by the test subject may be determined during the course of the inhalation compound test.Type: ApplicationFiled: June 21, 2013Publication date: November 14, 2013Inventors: Paul A.
