Patent number: 8657756Abstract: Methods and systems for evaluating a pathological condition include acquiring movement information, such as electromyogram (EMG) information, and sleep disordered breathing (SDB) information, and detecting the presence of a pathological condition using both movement and SDB information. Methods may involve sensing physiological signals including at least muscle movement signals. Sleep-related disorders are detected using the sensed physiological signals, the sleep-related disorders including at least an involuntary muscle movement disorder and sleep-disordered breathing.

Publication number: 20130331902Abstract: Cardiac monitoring and/or stimulation methods and systems employing dyspnea measurement. An implantable cardiac device may sense transthoracic impedance and determine a patient activity level. An index indicative of pulmonary function is implantably computed to detect an episode of dyspnea based on a change, trend, and/or value exceeding a threshold at a determined patient activity level. Trending one or more pulmonary function index values may be done to determine a patient's pulmonary function index profile, which may be used to adapt a cardiac therapy. A physician may be automatically alerted in response to a pulmonary function index value and/or a trend of the patient's pulmonary index being beyond a threshold. Computed pulmonary function index values and their associated patient's activity levels may be stored periodically in a memory and/or transmitted to a patient-external device.Type: ApplicationFiled: August 15, 2013Publication date: December 12, 2013Applicant: Cardiac Pacemakers, Inc.Inventors: Donald L.

Publication number: 20130296663Abstract: This patent document discusses, among other things, systems, devices, and methods for enhancing detection of pulmonary edema using, in addition to thoracic impedance, one or a combination of: physiologic information about a subject, at least one statistical parameter, a user-programmable detection level, at least one parameter associated with a previous pulmonary edema event, and patient symptom information about the subject. In one example, a (base) thoracic impedance threshold is modified to an adjusted thoracic impedance threshold. The adjusted thoracic impedance threshold provides an increased sensitivity of pulmonary edema detection as compared to the base thoracic impedance threshold. In another example, an alert is provided to a subject, a caregiver, or other user based on a pulmonary edema indication determined by the present systems, devices, and methods. In a further example, a therapy (provided to the subject) is adjusted or initiated in response to the pulmonary edema indication.Type: ApplicationFiled: July 2, 2013Publication date: November 7, 2013Inventors: Jeffrey E.

Publication number: 20130281867Abstract: Vector selection is automatically achieved via a thoracic or intracardiac impedance signal collected in a cardiac function management device or other implantable medical device that includes a test mode and a diagnostic mode. During a test mode, the device cycles through various electrode configurations for collecting thoracic impedance data. At least one figure of merit is calculated from the impedance data for each such electrode configuration. In one example, only non-arrhythmic beats are used for computing the figure of merit. A particular electrode configuration is automatically selected using the figure of merit. During a diagnostic mode, the device collects impedance data using the selected electrode configuration. In one example, the figure of merit includes a ratio of a cardiac stroke amplitude and a respiration amplitude. Other examples of the figure of merit are also described.Type: ApplicationFiled: June 24, 2013Publication date: October 24, 2013Inventors: Jonathan Kwok, Kent Lee, Jesse W. Hartley, Jeffrey E.

Patent number: 8323204Abstract: An event-based approach to collecting and organizing information associated with events affecting respiration is presented. The detection or prediction of an event affecting the respiration of a patient initiates acquisition of information associated with the event. The respiratory logbook system acquires information associated with the event during the event and during intervals proximate in time to the event. The information is organized as a respiratory log entry. The user can access the information by operating a user interface. The information may be presented in textual or graphical form.Type: GrantFiled: March 13, 2009Date of Patent: December 4, 2012Assignee: Cardiac Pacemakers, Inc.Inventors: Jeffrey E. Stahmann, John D.

Patent number: 8251061Abstract: A gas therapy system involves sensing the blood gas concentration of the patient and adapting a gas therapy based on the sensed gas concentration. Disordered breathing may be detected bases on blood gas concentration, and gas or cardiac electrical therapy may be adapted to treat the detected disordered breathing. One or more of sensing the blood gas concentration, detecting disordered breathing, or adapting the therapy may be performed at least in part implantably. The gas therapy is delivered to the patient through an external respiratory device, such as a positive airway pressure device.Type: GrantFiled: August 30, 2004Date of Patent: August 28, 2012Assignee: Cardiac Pacemakers, Inc.Inventors: Kent Lee, Jesse W.

Patent number: 8221327Abstract: Methods and systems provide an approach to therapy control based on assessment of a patient's cardiopulmonary status. Conditions sensed via sensors of an external respiratory therapy device are used to assess a patient's cardiopulmonary status. The respiratory therapy device sensors may be utilized alone or in combination with other sensors to determine cardiopulmonary status of a patient. Therapy delivered to the patient is controlled based on the cardiopulmonary status assessment. For example, therapy delivered to the patient may be initiated, terminated, and/or modified based on the assessed cardiopulmonary status of the patient. Cardiopulmonary status assessment, therapy control, or both, are performed by an implantable device.Type: GrantFiled: January 15, 2010Date of Patent: July 17, 2012Assignee: Cardiac Pacemakers, Inc.Inventors: Kent Lee, Jeffrey E.

Patent number: 8200326Abstract: A system includes an implantable medical device that includes a trans-thoracic impedance measurement circuit providing a trans-thoracic impedance signal of a subject. A controller is coupled to the trans-thoracic impedance circuit. The controller extracts a respiration signal from the trans-thoracic impedance signal, measures a breathing volume of the subject using the amplitude of the respiration signal and a breathing volume calibration factor, computes an adjusted breathing volume calibration factor using a reference baseline value of the trans-thoracic impedance and a measured baseline value of the trans-thoracic impedance, and computes a calibrated breathing volume using the adjusted breathing volume calibration factor.Type: GrantFiled: September 10, 2009Date of Patent: June 12, 2012Assignee: Cardiac Pacemakers, Inc.Inventors: John D.
