Patent number: 10226197Abstract: In situations in which an implantable medical device (e.g., a subcutaneous ICD) is co-implanted with a leadless pacing device (LPD), it may be important that the subcutaneous ICD knows when the LPD is delivering pacing, such as anti-tachycardia pacing (ATP). Techniques are described herein for detecting, with the ICD and based on the sensed electrical signal, pacing pulses and adjusting operation to account for the detected pulses, e.g., blanking the sensed electrical signal or modifying a tachyarrhythmia detection algorithm. In one example, the ICD includes a first pace pulse detector configured to obtain a sensed electrical signal and analyze the sensed electrical signal to detect a first type of pulses having a first set of characteristics and a second pace pulse detector configured to obtain the sensed electrical signal and analyze the sensed electrical signal to detect a second type of pulses having a second set of characteristics.Type: GrantFiled: April 15, 2015Date of Patent: March 12, 2019Assignee: Medtronic, Inc.Inventors: James D. Reinke, Xusheng Zhang, Vinod Sharma, Vladimir P. Nikolski, Michael B. Terry, Scott A. Hareland, Daniel L. Hansen, Donna M. Salmi

Publication number: 20150305640Abstract: In situations in which an implantable medical device (IMD) (e.g., an extravascular ICD) is co-implanted with a leadless pacing device (LPD), it may be important that the IMD knows when the LPD is delivering pacing, such as anti-tachycardia pacing (ATP). Techniques are described herein for detecting, with the IMD and based on the sensed electrical signal, pacing pulses and adjusting operation to account for the detected pulses, e.g., blanking the sensed electrical signal or modifying a tachyarrhythmia detection algorithm. In one example, the IMD includes a pace pulse detector that detects, based on the processing of sensed electrical signals, delivery of a pacing pulse from a second implantable medical device and blank, based on the detection of the pacing pulse, the sensed electrical signal to remove the pacing pulse from the sensed electrical signal.Type: ApplicationFiled: April 15, 2015Publication date: October 29, 2015Inventors: James D. REINKE, Xusheng ZHANG, Vinod SHARMA, Vladimir P. NIKOLSKI, Michael B. TERRY, Scott A. HARELAND, Daniel L. HANSEN, Donna M. SALMI

Patent number: 8720276Abstract: An implantable medical sensor system provides signals representative of a magnitude of moment fraction applied to a sensor module at a selected site. A sensor module includes a first transducer producing a first signal having an associated first response to pressure and strain applied to the sensor module and a second transducer producing a second signal having an associated second response to pressure and strain applied to the sensor module. A moment fraction is computed in response to the first signal and the second signal.
