Publication number: 20120108993Abstract: An improved design for subcutaneous monitors that addresses the problem caused by bubbles of air may remain in the pocket in which the device is implanted. As implantable monitors and their associated electrodes are reduced in size, these bubbles may in some cases cover one or both electrodes, interfering with sensing of the ECG signal. The invention addresses this problem by configuring the electrodes to increase the pressure of the electrodes against the tissue above the electrodes relative to the pressures exerted by the adjacent outer facing surfaces of the device.Type: ApplicationFiled: October 26, 2011Publication date: May 3, 2012Applicant: Medtronic, Inc.Inventors: Charles R.

Patent number: 7766826Abstract: A system and method for storing and processing physiological data in a medical recording device that allows continuous data collection and storage of such data in multiple time-resolved levels are provided. The method includes: sampling one or more physiological signals at a selected sampling rate; deriving physiological parameter values from the sampled signal; storing the parameter values as they are determined in a temporary memory buffer for a predetermined storage interval; determining a statistical aspect of the stored parameter values upon expiration of the storage interval; and writing the statistical aspect to a long-term memory buffer. A number of long-term memory buffers may be designated for storing a statistical aspect of a physiological parameter at uniquely different time resolutions. The resolution of each long-term memory buffer is determined by the storage interval defined for an associated temporary memory buffer, which stores parameter values from which statistical aspects are computed.Type: GrantFiled: November 26, 2003Date of Patent: August 3, 2010Assignee: Medtronic, Inc.Inventors: Brian B. Lee, Tommy D. Bennett

Patent number: 7634310Abstract: A method and apparatus for detecting atrial arrhythmias include acquiring a cardiac signal comprising R-waves. Differences between pairs of consecutive R-R intervals occurring during a first time interval are computed from the cardiac signal. An atrial arrhythmia is detected subsequent to the first time interval in response to the computed differences. Storage of the cardiac signal is triggered in response to the atrial arrhythmia detection.Type: GrantFiled: October 30, 2006Date of Patent: December 15, 2009Assignee: Medtronic, Inc.Inventors: Brian B.

Publication number: 20080081958Abstract: An implantable medical device (IMD) applies a sensor self-test when a sensing device generates a sensor signal indicating an event, or when the sensor is used to validate an event detected by another device. The event may be based on a sensed condition that triggers an operational adjustment, such as a therapy or diagnostic adjustment within the IMD. A sensor self-test verifies that an implantable sensing device is functional, and can be performed with or without activating the sensor. Activating the sensor may involve, application of an electrical input signal that causes the sensor to generate an output signal. Alternatively, the sensor self-test may be performed without activating the sensor by analyzing the continuity of a signal path between the sensor and sensor interface circuitry. In either case, a sensor self-test verifies proper operation so that operational adjustments can be made with greater confidence.Type: ApplicationFiled: April 24, 2007Publication date: April 3, 2008Applicant: Medtronic, Inc.Inventors: Timothy J. Denison, Brian B. Lee, Keith A. Miesel, Eric J. Panken

Patent number: 7035684Abstract: A minimally invasive, implantable monitor and associated method for chronically monitoring a patient's hemodynamic function based on signals sensed by one or more acoustical sensors. The monitor may be implanted subcutaneously or submuscularly in relation to the heart to allow acoustic signals generated by heart or blood motion to be received by a passive or active acoustical sensor. Circuitry for filtering and amplifying and digitizing acoustical data is included, and sampled data may be continuously or intermittently written to a looping memory buffer. ECG electrodes and associated circuitry may be included to simultaneously record ECG data. Upon a manual or automatic trigger event acoustical and ECG data may be stored in long-term memory for future uploading to an external device. The external device may present acoustical data visually and acoustically with associated ECG data to allow interpretation of both electrical and mechanical heart function.Type: GrantFiled: February 26, 2003Date of Patent: April 25, 2006Assignee: Medtronic, Inc.Inventor: Brian B. Lee

Patent number: 7016721Abstract: Triggers and noise should be available as information in recorded electrograms in memories of implantable medical devices. Particularly where the recording of electrogram data is done in the far field, there will be considerable noise and the interpretation of ECG's reproduced from such recorded data will benefit from the storing of information regarding contemporaneous noise. By storing contemporaneous trigger data and noise data directly in the ECG data, recordings of the ECG data become more useful for physician use when played back through an external display system with minimal loss of ECG data, since out of range values are employed for the noise and trigger information and this non-ECG data is limited in size to no longer than individual point values of the ECG signal.Type: GrantFiled: October 10, 2001Date of Patent: March 21, 2006Assignee: Medtronic, Inc.Inventors: Brian B. Lee, Michael R. Kane

Patent number: 6869404Abstract: A minimally invasive, implantable heart sound and ECG monitor and associated method for deriving blood pressure from heart sound data. The device is equipped with an acoustical sensor for detecting first and second heart sounds which are sampled and stored during sensing windows following R-wave and T-wave detections, respectively. ECG and heart sound data are stored in a continuous, looping memory, and segments of data are stored in long-term memory upon an automatic or manual data storage triggering event. Estimated blood pressure is calculated based on custom spectral analysis and processing of the first and second heart sounds. A calibration method includes measuring a patient's blood pressure using a standard clinical method and performing regression analysis on multiple spectral variables to identify a set of best fit weighted equations for predicting blood pressure. Concurrent ECG and estimated blood pressure may be displayed for review by a physician.Type: GrantFiled: February 26, 2003Date of Patent: March 22, 2005Assignee: Medtronic, Inc.Inventors: Randal C.
