Problems solved by technology

This can lead to the fact that the performance of the active implantable medical device may degrade when the check has already taken place, and thus the battery is no longer able to support the load, or indeed, the RF link may be interrupted once the threshold is reached

Embodiment Construction

[0048] In order to ensure that the battery of an active implantable medical device with a radio frequency communication part RF can still provide the power required to transmit RF data, the present invention proposes a method that can be used to periodically A method of checking the state of the battery (for example, every day). The conditions for RF transmission are usually predetermined, and the transmission speed, the size of the memory pool to be transmitted and the duration of the communication are known. There are various types of RF communication, such as, for example, periodic wake-ups with brief communications lasting from a few milliseconds to tens of milliseconds, in order to check whether communication is necessary (e.g. by using the "advertising" mode of the Bluetooth standard) . Communication over RF can also be used to send a message indicating whether to communicate with another device. It may be a communication with a data transmission of less than 1 second ...

Abstract

Disclosed is an active implantable medical device, espeically a a method for determining usable capacity of a battery of the active implantable medical device comprising a radiofrequency (RF) communication unit for transmitting data by RF over a communication period, wherein the usable capacity of the battery enables the active implantable medical device to transmit data by RF via the RF communication unit. The method includes a) measuring a value for the voltage of the battery which is representative of an instantaneous voltage drop of the battery as a result of a current draw on the battery, b) comparing the voltage of the battery with a predetermined threshold voltage VBS, and c) transmitting an alert message to a second device when the measured voltage of the battery crosses the predetermined threshold voltage.The invention also relates to the active implantable medical device that performs the method.

Description

technical field [0001] The present invention relates to an active implantable medical device, in particular a cardiac stimulator or a neurostimulator, equipped with a radio frequency (RF) link, in particular with a for communicating with another device, in particular another external non-implantable device. Background technique [0002] The active implantable device may include a radio frequency (RF) communication unit for enabling communication with another device, especially an external device such as a programmer used by a practitioner, a home monitor, a smartphone or any other device . Here, the term "communication" should be understood to mean any communication between an implantable device and another device, whether or not there is a response from the other device. [0003] For patients wearing active implantable medical devices with RF communication components, it is critical to be able to determine the usable capacity of the battery for this type of device. Excep...
