Device longevity prediction for a device having variable energy consumption
First Claim
1. A system for estimating a life of a power source of an implantable medical device (IMD), the system comprising:
- a therapy logic configured to provide an open-loop stimulation therapy, an automatic closed-loop stimulation therapy, and a manually-initiated closed-loop stimulation therapy to a patient;
a detection logic coupled to the therapy logic, the detection logic configured to detect one or more events for triggering the automatic closed-loop stimulation therapy and the manually-initiated closed-loop stimulation therapy, and to record the one or more events; and
a control device coupled to the therapy logic and the detection logic, the control device configured to provide a first operable life estimate of the power source of the IMD, wherein the first operable life estimate identifies a first open-loop stimulation therapy portion of the first operable life estimate, a first automatic closed-loop stimulation therapy portion of the first operable life estimate, and a first manually-initiated closed-loop stimulation therapy portion, and where the first operable life estimate is based on an open-loop value corresponding to an open-loop parameter for the open-loop stimulation therapy, a closed-loop value corresponding to a closed-loop parameter for the automatic closed-loop stimulation therapy, a second closed-loop value corresponding to a manually-initiated closed-loop parameter for the manually-initiated closed-loop stimulation therapy, and a prior usage data corresponding to prior therapy delivery.

Abstract
A system and method for estimating the longevity of an implantable medical device (IMD). In one embodiment of a method for estimating a life of a power source of an implantable medical device, a first life estimate of the power source is determined based on a first open-loop value corresponding to an open-loop parameter for open-loop therapy delivery, a first closed loop value corresponding to a closed-loop parameter for closed-loop therapy delivery, and prior usage data corresponding to prior therapy delivery. The first life estimate of the power source is displayed. The first life estimate displayed includes a first open-loop portion associated with open-loop therapy delivery and a first closed-loop portion associated with closed-loop therapy delivery.
