  • Publication number: 20110245889
    Abstract: A cardiac rhythm management (CRM) system includes an implantable cardioverter defibrillator (ICD) and an external system. The ICD includes a plurality of functional modules performing tachyarrhythmia classification and therapy control functions using atrial tachyarrhythmia rate thresholds that are set to a unified value. In one embodiment, the CRM system allows a user to activate and deactivate each of the functional modules and program the unified value using the external system.

  • Patent number: 7979378
    Abstract: This document discusses, among other things, a user interface capable of resolving interactions between programmable parameters for operation of a personal medical device. Programming these devices is a difficult task when many parameters are involved. The medical device interface attempts to reduce and minimize constraint violations between interdependent parameters using an initial set of parameter values supplied by user (typically a physician) input, and constraint violations describing invalid parameter values. A user is given the option to select one or more parameters to remain constant. If possible, a set of parameter values with less egregious constraint violations is displayed to the user. A user is prompted to accept the set of parameter values and program the medical device.

  • Patent number: 7966069
    Abstract: An external programming system and method for implantable medical devices (IMDs) is disclosed. The external programming system includes a communication circuit, a display device, an input device, and a processor. The communication circuit is configured to link to an IMD to transmit or monitor IMD timing parameter settings. The display device is configured to display a textual representation of an IMD timing parameter setting and a specified IMD timing parameter limit, a graphical slide control comprising a movable feature indicating the IMD timing parameter setting, a graphical slide-control limit corresponding to the specified IMD timing parameter limit, and a graphical representation of physiologic information including a portion of said graphical representation aligned with the slide control movable feature. The input device is configured to adjust the movable feature in response to user input. The processor is configured to monitor or store an IMD timing parameter setting.

  • Publication number: 20110137368
    Abstract: A medical device programmer and a method of operation in which a first data value is received and used in the execution of one or more algorithms. One or more suggested pulse generator settings are calculated from the one or more algorithms based on the first data value, and the one or more suggested pulse generator settings are displayed on an interactive display screen of the medical device programmer. In one embodiment, the first data value is a duration interval of a QRS complex. From the duration interval, suggestions are made as to one or more ventricular chambers in which to provide pacing pulses. Additionally, pacing intervals for an AV delay are suggested based on measured P-R intervals, or pacing intervals for an LV offset are suggested based on a measured duration interval of a V-V-interval between a right ventricular event and a left ventricular event.

  • Publication number: 20110046692
    Abstract: A system and method for correlating health related data for display. The system includes a medical device recording data and a display producing device which correlates the data and simultaneously displays different types of data or displays two sets of the same type of data along with the circumstances at which the two sets of data were recorded. Such displays aid a physician in prescribing and ascertaining the efficacy of cardiac therapies.

  • Patent number: 7840265
    Abstract: A cardiac rhythm management (CRM) system includes an implantable cardioverter defibrillator (ICD) and an external system. The ICD detects a tachyarrhythmia episode and classifies the detected tachyarrhythmia episode using none, one, or more of detection enhancements selected according to a selection command including a classification mode. The detection enhancements are each an algorithm for detecting and analyzing one or more indications of a type of the detected tachyarrhythmia episode. The external system allows a user to select the classification mode from a plurality of available classification modes each using none, one, or more of the detection enhancements.

  • Publication number: 20100249868
    Abstract: Systems and methods for a configurable programmer for an implantable cardiovascular medical device are disclosed. A preferred embodiment comprises a graphical user interface to visualize programming processes to alert a clinician to potential problems with the patient's condition or the therapy provided by the device, or the device itself. The programmer is further adapted to minimize the risk of programming potentially dangerous changes to the implantable device's parameter settings by requiring the clinician to first review new value changes before initiating the programming step. The programmer also allows the clinician to view how a change to one or more parameter settings affect other settings before the implantable device is programmed or re-programmed.
