IMPLANTABLE MEDICAL DEVICE DIAGNOSTIC DATA ACQUISITION AND STORAGE
First Claim
1. A method carried out by a therapeutic implantable medical device (IMD), the method comprising:
- detecting a plurality of physiologic episodes;
recording a set of diagnostic data associated with the plurality of physiological episodes;
prioritizing the plurality of physiologic episodes based on episode types associated with the physiologic episodes;
analyzing the diagnostic data based on a minimum number and a maximum number associated with each episode type, wherein the minimum number indicates a minimum number of sets of diagnostic data to be recorded for the associated episode type, and wherein the maximum number indicates a maximum number of sets of diagnostic data to be recorded for the associated episode type; and
deleting the recorded set of diagnostic data only if a later recorded set of diagnostic data is associated with a detected physiologic episode having an episode type of a higher priority, and deletion of the set of diagnostic data would not result in fewer sets of diagnostic data than the minimum number specified for the episode type associated with the set of diagnostic data.

Abstract
A method carried out by a therapeutic implantable medical device includes detecting a plurality of physiologic episodes and recording a set of diagnostic data associated with the plurality of physiological episodes. The plurality of physiologic episodes are prioritized based on episode types associated with the physiologic episodes. The diagnostic data is analyzed based on a minimum and maximum number associated with each episode type relating to a minimum and maximum number of sets of diagnostic data to be recorded for the associated episode type. The recorded set of diagnostic data is deleted only if a later recorded set of diagnostic data is associated with a detected physiologic episode having an episode type of a higher priority, and deletion of the set of diagnostic data would not result in fewer sets of diagnostic data than the minimum number specified for the episode type associated with the set of diagnostic data.

16. An implantable medical device (IMD) configured for implantation in a patient to monitor cardiac activity in, and deliver therapy to, the patient'"'"'s heart, the IMD comprising:
-
a pulse generator operable to deliver pacing pulses and shock pulses; a plurality of leads having proximate ends coupled to the pulse generator and distal ends affixed to the patient'"'"'s heart at selected locations, wherein the leads are configured to pick up electrical activity in the patient'"'"'s heart, and wherein the leads are further configured to deliver the pacing pulses and the shock pulses to the patient'"'"'s heart; a memory storing a prioritization schedule of cardiac episodes, wherein the prioritization schedule specifies a priority for each of a plurality of types of cardiac episodes, a minimum number indicating a minimum number of data sets to be recorded for each of the cardiac episodes, and a maximum number indicating a maximum number of data sets to be recorded for each of the cardiac episodes; and a processor operable to delete a first recorded set of diagnostic data associated with a type of cardiac episode of a first priority, only if a second received set of diagnostic data is associated with a type of cardiac episode of a second priority that is higher than the first priority, and deletion of the first set of diagnostic data would not result in fewer sets of diagnostic data than the minimum number specified for the type of episode associated with the first set of diagnostic data. - View Dependent Claims (17, 18)
