20100016920 | SYSTEMS AND METHODS FOR COLLECTING PATIENT EVENT INFORMATION - A method of and system for collecting patient event information from a cardiac rhythm management system (CRM system) is described, where the CRM system includes a cardiac rhythm management device (CRM device) and an external interface device. The method includes the steps of initiating a transmission session wherein the interface device communicates with the CRM device, prompting a user of the CRM system to select a reason for the transmission session, inputting the selected reason for the transmission session to the interface device, and storing the selected reason for the transmission session and timestamp information for the transmission session. | 01-21-2010 |
20110093026 | METHOD AND APPARATUS FOR CARDIORENAL ELECTRICAL STIMULATION - An implantable cardiorenal stimulator delivers cardiorenal stimulation in response to detection of decompensation associated with heart failure. The cardiorenal stimulation includes delivering renal stimulation pulses to promote diuresis and/or natriuresis and delivering cardiac stimulation pulses to enhance the diuretic and/or natriuretic effects of the renal stimulation pulses. | 04-21-2011 |
20120143286 | SYSTEMS AND METHODS FOR INCREASING STIMULATION DOSE - According to an embodiment of a method performed by an implantable medical device to deliver a neural stimulation therapy to a patient, a lower dose of the neural stimulation therapy is delivered to the patient. The dose of the neural stimulation therapy is automatically increased from the lower dose to a higher dose, and the higher dose of the neural stimulation therapy is delivered to the patient. A trigger that is controlled by the patient is detected, and the dose of the neural stimulation therapy is automatically returned from the higher dose back to the lower dose in response to detecting the trigger. | 06-07-2012 |
20120303086 | SYSTEMS AND METHODS FOR COLLECTING PATIENT EVENT INFORMATION - A method of and system for collecting patient event information is described, where the system includes an implantable medical (IMD) and an external interface device. The external interface device is remote from the IMD and includes a communication module, a display device adapted to prompt a user of the system to select a reason for a particular transmission session and a user input device adopted to accept input indicating a selected reason. | 11-29-2012 |
20130053914 | METHOD AND APPARATUS FOR ADAPTIVE CONTROL OF NEUROSTIMULATION USING CARDIAC RESTITUTION - A neurostimulation system measures a cardiac parameter at various cardiac intervals and analyzes its restitution, including computing a restitution slope being a rate of change of the restitution parameter with respect to change in the cardiac interval. In various embodiments, the system uses the restitution slope to provide for adaptive control of neurostimulation. In various embodiments, one or more cardiac parameters such as action potential duration (APD), conduction velocity (CV), QT interval (QT), and/or T-wave morphology (TM) parameter are measured and analyzed for restitution of each parameter, which is then used to control the delivery of the neurostimulation. | 02-28-2013 |
20130053926 | SYSTEMS TO DETECT VAGUS CAPTURE - Some embodiments provide a system for delivering neurostimulation. Some system embodiments comprise a lead configured to be implanted in the body, a stimulation output circuit configured to deliver neurostimulation pulses to the vagus nerve through the lead, an EMG sensing circuit configured to use the lead to sense EMG signals from laryngeal muscle activity, and an evoked muscular response detection circuit configured to use the EMG signals sensed by the EMG sensing circuit to detect evoked laryngeal muscle activity evoked by the neurostimulation pulse. | 02-28-2013 |
20130158621 | ECTOPIC-TRIGGERED PARA-HIS STIMULATION - Ectopic cardiac activity can be detected, such as in the absence of a diagnosed tachyarrhythmia episode. In response to the detected ectopic activity, electrostimulation can be provided to a para-Hisian region, such as to activate natural cardiac contraction mechanisms or to interrupt re-entrant cardiac activity. Subsequent ectopic cardiac activity can be detected, and subsequent electrostimulation can be provided to the para-Hisian region, such as according to one or more adjustable electrostimulation parameters. | 06-20-2013 |
20130345591 | METHOD FOR DETECTING VAGUS CAPTURE - Some embodiments provide a system for delivering neurostimulation. Some system embodiments comprise a lead configured to be implanted in the body, a stimulation output circuit configured to deliver neurostimulation pulses to the vagus nerve through the lead, an EMG sensing circuit configured to use the lead to sense EMG signals from laryngeal muscle activity, and an evoked muscular response detection circuit configured to use the EMG signals sensed by the EMG sensing circuit to detect evoked laryngeal muscle activity evoked by the neurostimulation pulse. | 12-26-2013 |
