  • Publication number: 20100016996
    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.

  • Publication number: 20090182517
    Abstract: Abnormal battery depletion can be detected in an implantable medical device. Battery capacity consumed can be measured using a coulometer and using a capacity-by-voltage device, and the measurements can be blended to determine battery status. A drop in battery voltage below a specified threshold can be detected to identify a high-current depletion fault, and an alarm can be provided to indicate the fault has been detected. The specified threshold can be determined as a function of battery capacity consumed. Other aspects and embodiments are provided herein.

  • Publication number: 20090171414
    Abstract: A system and method is provided for receiving user input to perform an initial interrogation of an implantable medical device (IMD) using an external device. The initial interrogation commences a communication session between the IMD and the external device. During the initial interrogation, first data is transferred from the IMD to the external device and displayed at the external device. The first data comprises device configuration data of the IMD. During the initial interrogation, background transfer of second data from the IMD to the external device is initiated during or after the display of first data, without requiring a user request for the second data. The second data comprises historical physiological episode data.

  • Publication number: 20090171412
    Abstract: A system and method for handling data received from an implantable medical device (IMD) is provided. The method includes communicating a device parameter value of an IMD device parameter from the IMD to an external device and determining, at the external device, that the communicated device parameter value is at an improper value. Additionally, in response to the determining that the communicated device parameter value is at an improper value, automatically performing at least one of re-programming the IMD device parameter with a selected substitute device parameter value, ignoring, or purging non-programmable data.

  • Publication number: 20090088815
    Abstract: This document discusses, among other things, an external device that includes a communication circuit, a programming interface including a display, and a processor. The processor includes a parameter analyzer to apply a rule to a combination of operating parameter values of the IMD to determine operating parameter interaction. The display includes a first warning that is displayed when the parameter analyzer determines that a combination of operating parameter values entered via the programming interface is not allowed, and a second warning that is displayed when the parameter analyzer determines that a combination of operating parameters values entered via the programming interface is allowable but not recommended. The processor is configured to program the operating parameter values associated with the second warning into the IMD only after a user acknowledgement of the second warning is received from a user via the programming interface.

  • Patent number: 7457663
    Abstract: A cardiac rhythm management system includes techniques for reducing the number of programmable variables associated with maximum pacing rate so that fewer variables are programmed and a reduction in possible parameter conflict is achieved. In an embodiment, a maximum pacing rate parameter replaces a plurality of conventional, separately programmable pacing parameters. For example, maximum tracking rate, maximum sensor rate, rate smoothing maximum pacing rate, atrial pacing preference maximum pacing rate, and ventricular rate regulation maximum pacing rate are replaced by a single maximum pacing rate with, if necessary, a sensor offset and an atrial pacing preference offset. In another example, rate smoothing maximum pacing rate, biventricular trigger maximum pacing rate and ventricular rate regulation maximum pacing rate are replaced by a single maximum pacing rate.
