Abstract:
Embodiments of the invention are related to systems for interfacing with implantable medical devices, amongst other things. In an embodiment, the invention includes an external medical system including a processor and a telemetry circuit in communication with the processor, the processor configured to communicate with an implanted medical device. The system can be configured to query a system user after a first period of time in which indicators of system use are not detected. The system can be further configured to deactivate one or more data transmission features of the implanted medical device after a second period of time in which one or more indicators of system use are not detected. Other embodiments are also included herein.
Abstract:
One way in which cardiac resynchronization therapy may be delivered is to only deliver paces to the left ventricle. If left ventricular pacing is inhibited during a cardiac cycle, it may be desirable to deliver a right ventricular safety pace to prevent asystole. Methods and devices for implementing right ventricular safety pacing in the context of multi-site left ventricular-only pacing are described.
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.
Abstract:
In one aspect a system includes an external communication device configured to interrogate a pulse generator, an external programmer device communicatively coupled to the external communication device; the external programmer device configured to receive a listing of valid electrode pairs from the pulse generator through the external communication device, the external programmer device configured to prevent a pacing, sensing, or shocking vector from being programmed by the user if a pair of electrodes needed for the vector are not included within the listing of valid electrode pairs. In another aspect a system includes an implantable medical device configured to detect the presence or absence of electrodes on an implanted stimulation lead coupled to the implantable medical device and to generate a valid electrode pair listing and compare the programmed electrode pairs with the valid electrode pair listing. Other embodiments are also included herein.
Abstract:
One aspect of this disclosure relates to a system for dynamic battery management in implantable medical devices. An embodiment of the system includes two or more devices for measuring battery capacity for an implantable medical device battery. The embodiment also includes a controller connected to the measuring devices. The controller is adapted to combine the measurements from the measuring devices using a weighted average to determine battery capacity consumed. According to various embodiments, at least one of the measuring devices includes a coulometer. At least one of the measuring devices includes a capacity-by-voltage device, according to an embodiment. The system further includes a display in communication with the controller in various embodiments. The display is adapted to provide a depiction of battery longevity in units of time remaining in the life of the implantable medical device battery, according to various embodiments. Other aspects and embodiments are provided herein.
Abstract:
Systems, devices and methods are provided for displaying statistical distributions of cardiac events. A device embodiment comprises circuitry adapted to communicate with a medical device that is adapted to acquire data regarding cardiac events occurring at two or more cardiac sites, and display means for displaying a histogram of the data as two or more statistical distributions for the two or more cardiac sites. The histogram includes a number of histogram bins. At least one of the histogram bins includes both a representation for at least a portion of a statistical distribution of a cardiac event for a first cardiac site and a representation for at least a portion of a statistical distribution of a cardiac event for a second cardiac site. Other embodiments are provided herein.
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.
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.
Abstract:
This document describes, among other things, a method of operating a medical device comprising updating a regulatory approval status stored in at least one of the medical device or a second device operable to communicate with the medical device, and enabling or disabling the at least one function in the medical device based on the regulatory approval status. The regulatory approval status corresponds to at least one function performable by the medical device.
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.
