The CHIRP system is not intended to provide real time data like a smart watch or smart phone.
Rather, it collects data over the course of a day, analyzes it while the patient is asleep, and
presents the previous day’s data for HCP and patient review the following day.
The CTE implant has the ability to store 30 day of data. Therefore, if the patient’s Home Base
Station connection is temporarily lost or they are traveling for less than 30 days without a Home
Base Station, the full amount of data will be uploaded to the Canary Cloud once a connection is
made to the Home Base Station. If there is no connection for periods greater than 30 days, new
data will over-write the oldest data until a connection to the patient’s Home Base Station and
the Canary Cloud is made.
The CTE implant has been programed to collect data using the following schedule.
Time Period Sampling
Day 0 (surgery) to Day 1 No sampling
Day 2 to Day 365 Daily
Year 2 30 consecutive Days/Quarter
Years 3 and beyond 30 consecutive days commencing on the
anniversary of the patient’s your surgery date
When the CTE is not sampling, it is in a low power mode to conserve battery power. When
viewing a patient’s data, if no values are present during a particular day or period of time, it
simply means during this period the CTE was not collecting data per its program.
