Implantable medical device capable of prioritizing diagnostic data and allocating memory for same
First Claim
1. A method executable by a body-implantable device having at least one physiologic sensor, comprising the steps of:
- receiving sensor data from the physiologic sensor;
determining whether said sensor data exceeds a threshold value;
determining for said sensor data which exceeds said threshold value, whether sufficient memory is available to store said sensor data;
determining a priority value for said sensor data;
determining if data with a lower priority value exists in memory, andoverwriting with said sensor data said data with a lower priority value;
wherein said step of determining said priority value involves taking into account the amount of memory required to store said sensor data and a clinical significance value associated with said sensor data.

Abstract
A body implantable device having at least one physiologic sensor capable of monitoring performance of the device and physiologic indicators of the patient is disclosed. The device is capable of determining whether an event or indicator being monitored is beyond certain threshold levels that indicate an event or indicator may be clinically significant. The device can determine the relative importance of the event or indicator in contrast to other events or indicators for which data have been previously stored. The device is further capable of allocating memory for data relating to the higher priority events or indicators.

3. A method of allocating a limited amount of memory in a body implantable device having at least one implantable physiologic sensor, comprising the steps of:
-
determining the clinical significance of data received from the at least one physiological sensor; storing data received from the at least one physiologic sensor that is of clinical significance in a memory as it is received until new data is received from the sensor that is of clinical significance for which there is not enough space in memory for said new data to be stored; determining whether compression of the data in said memory would create enough memory space for said new data; compressing the data; and storing said new data in said memory. - View Dependent Claims (4)
