Patent number: 8827913Abstract: An example system may include at least one pressure sensor configured to measure a cardiovascular pressure signal and another medical device configured to measure an electrical depolarization signal of the heart. The system determines a plurality of cardiovascular pressure metrics based on the measured cardiovascular pressure signal, including at least one cardiovascular pressure metric indicative of a timing of at least one cardiac pulse. The system also determines a metric indicative of a timing of at least one heart depolarization within the measured electrical depolarization signal. The system compares the timing of the at least one cardiac pulse to the timing of the at least one depolarization, and determines whether to discard the plurality of cardiovascular pressure metrics based on whether the timings substantially agree.Type: GrantFiled: May 3, 2011Date of Patent: September 9, 2014Assignee: Medtronic, Inc.Inventors: William J. Havel, Tommy D. Bennett, Yong Kyun Cho, Robert T. Taepke, II

Patent number: 8062227Abstract: Heart failure decompensation is detected by sensing at least one physiological signal. Values of at least two different heart failure variables are derived using one or more physiological signals and a threshold for the first heart failure variable is adjusted in response to the value of the second heart failure variable. The value of the first heart failure variable is compared to first threshold for detecting a heart failure condition.Type: GrantFiled: October 30, 2008Date of Patent: November 22, 2011Assignee: Medtronic, Inc.Inventors: Yong K. Cho, Shantanu Sarkar, Douglas A. Hettrick, Robert T. Taepke, II, Tommy D. Bennett

Patent number: 7704209Abstract: A system and method are provided for sensing cardiac electrogram (EGM) signals and ventricular pressure signals and for using the sensed EGM and sensed pressure signals for estimating stroke volume (SV). A measure of cardiac output can be computed from the estimated SV and a heart rate determined from the EGM signals. The sensed ventricular pressure signal and the sensed EGM signal are used to derive landmark points such as an estimated pulmonary diastolic pressure, a mean pulmonary artery pressure, a peak right ventricular pressure (RVP), and various time intervals used in computing an area or a pulse contour integral. The pulse contour integral is used to estimate SV. The estimated pulmonary diastolic pressure, mean pulmonary artery pressure and CO computed from the estimated SV can be used to compute a pulmonary vascular resistance.Type: GrantFiled: February 11, 2009Date of Patent: April 27, 2010Assignee: Medtronic, Inc.Inventors: Tommy D. Bennett, Robert T. Taepke, II, Barbro M. Kjellstrom

Patent number: 6234973Abstract: An implantable barometric pressure sensor coupled with an implantable medical device (IMD) provides a barometric pressure related, reference pressure value for use in combination with an absolute pressure value measured by an implantable absolute pressure sensor coupled to the IMD. In one embodiment, the barometric pressure sensor is implanted under the skin and subcutaneous tissue layer at or near the implant site of the IMD. In variations of this embodiment, the barometric pressure is formed as part of a connector module of the IMD or extends from the connector module. In a further embodiment, a percutaneous access device is provided which is adapted to be implanted to extend through the skin and subcutaneous tissue layer of the patient and is coupled with the barometric pressure sensor to provide for an air chamber extending between the atmosphere and the barometric pressure sensor.Type: GrantFiled: November 18, 1999Date of Patent: May 22, 2001Assignee: Medtronic, Inc.Inventors: John T. Meador, Keith A. Miesel, Louis E. Halperin, Robert T. Taepke, II, Lee Stylos
