Techniques for data retention upon detection of an event in an implantable medical device
First Claim
1. A method of selective data retention in an implantable medical device, the method comprising:
- initiating loop recording in an implantable medical device upon determination of a neurological event, wherein the loop recording comprises storing a data record of a plurality of data records in a data structure, the plurality of data records representing information about determined neurological events, the data structure being a buffer wherein some data records of the plurality of data records stored on the data structure are selectively replaced as new data is received in the buffer;
determining a priority index for the plurality of data records based on severity levels of the determined neurological events; and
replacing older data records of the plurality of data records on the data structure with new data records according to the priority index, wherein the new data records selectively replace those data records in the data structure having the lowest associated priority index.

Abstract
Methods and apparatus for storing data records associated with a medical monitoring event in a data structure. These include initiating loop recording in an implantable medical device upon determination of a neurological event, wherein loop recording comprises storing a data record of a plurality of data records in a data structure, the plurality of data records representing information about determined neurological events. Methods and apparatus can further include determining a priority index for the plurality of data records based on severity levels of the determined neurological events and replacing older data records of the plurality of data records on the data structure with new data records according to the priority index, wherein the new data records selectively replace those data records in the data structure having the lowest associated priority index.

11. An implantable medical device comprising:
-
a monitoring element configured to sense one or more signals associated with a plurality of neurological events; a memory component, the memory component comprising a buffer and being configured to store a plurality of data records in a data structure and replace some of the data records of the plurality of data records stored on the data structure as new data records of the plurality of data records are received in the memory component, the plurality of data records associated with the neurological events; and a processing component, the processing component configured to detect the neurological events, initiate loop recording in the memory component of data records of the plurality of data records upon neurological event detection, determine a priority index for the plurality of data records based on severity levels of the detected neurological events, and selectively replace older data records of the plurality of data records on the data structure with new data records according to the priority index, the new data records selectively replacing those data records in the data structure having the lowest associated priority index. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. An implantable medical device comprising:
-
means for initiating loop recording upon determination of a neurological event, wherein loop recording comprises storing a data record of a plurality of data records in a data structure, the plurality of data records representing information about determined neurological events, wherein some data records of the plurality of data records stored on the data structure are selectively replaced as new data is received; means for determining a priority index for the plurality of data records based on severity levels of the determined neurological events; and means for replacing older data records of the plurality of data records on the data structure with new data records according to the priority index, wherein the new data records selectively replace those data records in the data structure having the lowest associated priority index.
