Abstract
A system including a controller to determine an in-body time of a medical device in a patient during a medical procedure. The controller to: receive signals from at least one temperature sensor; detect insertion of the medical device into the patient by one or more of determining the temperature of the medical device and determining the change of temperature of the medical device with respect to time; increment an in-body time counter to measure the in-body time of the medical device after detecting insertion of the medical device into the patient; detect that the medical device has been removed from the patient by determining that the change of temperature of the medical device with respect to time is negative; and stop incrementing the in-body time counter in response to detecting that the medical device has been removed.
