20120029362 | APNEA TYPE DETERMINING APPARATUS AND METHOD - An apnea classification system provides for apnea monitoring and differentiation based on several sleep apnea related parameters for diagnostic and therapeutic purposes. Monitoring of such sleep apnea related parameters allows the apnea classification system to differentiate among the different types of apnea and hypopnea and to identify an occurrence of periodic respiration. This information may then be used to determine the best method of therapy, or adjust current therapy parameters to more effectively treat a subject. | 02-02-2012 |
20120046709 | METHOD AND APPARATUS FOR CONTROLLING NEURAL STIMULATION DURING DISORDERED BREATHING - A neural stimulation system controls the delivery of neural stimulation using a respiratory signal as a therapy feedback input. The respiratory signal is used to increase the effectiveness of the neural stimulation, such as vagal nerve stimulation, while decreasing potentially adverse side effects in respiratory functions. In one embodiment, the neural stimulation system detects apnea and, in response, adjusts the delivery of the neural stimulation pulses and/or delivers a respiratory therapy treating the detected apnea. | 02-23-2012 |
20120130446 | METHOD AND APPARATUS FOR NEURAL STIMULATION WITH RESPIRATORY FEEDBACK - A neural stimulation system controls the delivery of neural stimulation using a respiratory signal as a therapy feedback input. The respiratory signal is used to increase the effectiveness of the neural stimulation, such as vagal nerve stimulation, while decreasing potentially adverse side effects in respiratory functions. In one embodiment, the neural stimulation system synchronizes the delivery of the neural stimulation pulses to the respiratory cycles using a respiratory fiducial point in the respiratory signal and a delay interval. In another embodiment, the neural stimulation system detects a respiratory disorder and, in response, adjusts the delivery of the neural stimulation pulses and/or delivers a respiratory therapy treating the detected respiratory disorder. | 05-24-2012 |
20120283527 | RESPIRATION MONITORING FOR HEART FAILURE USING IMPLANTABLE DEVICE - An implantable respiration monitor can be used to detect disordered breathing or periodic breathing events that can be categorized, such as according to one or more of sleep, exercise, and resting awake states. The categorized frequency of such events can be compared to independently specifiable thresholds, such as to trigger an alert or responsive therapy, or to display one or more trends. The information can also be combined with detection of one or more other congestive heart failure (CHF) symptoms to generate a CHF status indicator or to trigger an alarm or responsive therapy or to display one or more trends. The alert can notify the patient or a caregiver, such as via remote monitoring. The sleep state information can be further categorized according to central sleep apnea (CSA) or obstructive sleep apnea (OSA) events. | 11-08-2012 |
