Marker channel telemetry system for a medical device
First Claim
1. An implantable medical device of the type having means for detecting physiological events and having means for stimulating physiological activity and having a telemetry system for non-invasive communication with a remote receiver, said telemetry system comprisingmeans responsive to the detection of physiological events for producing a sensed event signal,latch means responsive to said sensed event signal for storing a signal indicating the occurrence of said sensed event,means responsive to the stimulation of physiological activity for producing a stimulated event signal,latch means responsive to said stimulated event signal for storing a signal indicating the occurrence of said stimulated event,encoding means for producing event identifying codes each representative of a said stored signal, andmeans for serially transmitting said event identifying codes to said remote receiver.

Abstract
A marker channel telemetry system for use with a pacemaker or other medical device for transmitting event identifying codes to a remote receiver to indicate the occurrence of specific events such as sensed and paced events in a dual chamber pacemaker. The structure of the system includes latches to store event information and for forming the marker codes. The system also includes a serial telemetry transmitter for transmitting the data to the remote receiver.
