Abstract
An implantable device which stores information indicative of events occurring within a patient's body and related to operation of the device for transmission to an external device in response to a request from the external device. The implanted device is provided with a mechanism for retaining information as to the state of the information stored in the device at the time of a preceding request or interrogation from the external device and for storing cumulative information indicative of the operation of the device or events occurring within the patient's body over a time frame spanning multiple interrogations or requests from the external device. The two types of stored information together may be employed by the implanted device or the external device to derive information indicative only of events occurring since a preceding interrogation of the implanted device by the external device.
