A device for enabling immediate retrieval of information and identification from an implantable medical device having a spent energy source

摘要

An implantable medical device comprising: an antenna for receiving and transmitting telemetry signals; a rectifier circuit connected to the antenna; a major electrical power source to power the implantable medical device; an additional power source connected to the rectifier circuit with an energy storage device for storing enough energy to provide power to excite the implantable medical device, the power being received from an external source via telemetry signals; a comparator for comparing voltage levels of the main power source and the additional power source and outputting a signal indicating which power source is stronger; and a voltage shifter designed to receive the comparator output signal, the voltage shifter allowing current to flow from either the main power source or the additional power source based on the signal received from the comparator to power the implantable medical device , which enables communication with an external programmer via telemetry query of identifications ...
