Telemetry transmission system for analog and digital data from an implanted source
Abstract
Abstract Translated from English Un systeme de transmission amelioree par telemetrie (10) permet de transmettre des informations electrocardiographiques, des indications du pouls et des informations codees numeriquement provenant d'un stimulateur cardiaque implante, d'un dispositif de distribution de produits medicamenteux ou autre dispositif vers un recepteur eloigne (12). Une telemetrie a deux voies est effectuee par le commutateur (32) qui syntonise le circuit reservoir (40, 42) au moyen d'un condensateur (44) pour recevoir des signaux de commande externes. An improved telemetry transmission system (10) transmits electrocardiographic information, pulse indications and digitally encoded information from an implanted pacemaker, drug delivery device or other device to a remote receiver (12). Two-way telemetry is performed by the switch (32) which tunes to the tank circuit (40, 42) by means of a capacitor (44) to receive external control signals.
