Device longevity prediction for a device having variable energy consumption

摘要

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.

1. A system for estimating a life of a power source of an implantable medical device (IMD), the system comprising:
a therapy logic, wherein the therapy logic provides:
an open-loop stimulation therapy; anda closed-loop stimulation therapy, wherein the closed-loop stimulation therapy comprises at least one of:
a patient initiated stimulation therapy; andan event detection stimulation therapy; a detection logic, wherein the detection logic:
detects a change in one or more body parameters;detects a patient input; andtriggers a change from the open-loop stimulation to the closed loop stimulation therapy based upon a detection of either a change in one or more body parameter or a patient input; and a control device, wherein the control device:
calculates an open-loop life estimate of the power source, wherein the open-loop life estimate is based upon a set of open-loop stimulation parameters;calculates a closed-loop charge consumption, wherein the closed-loop charge consumption is based upon a set of closed loop stimulation parameters; andprovides a first operable life estimate, wherein the first operable life estimate comprises a difference resulting from subtracting the closed-loop charge consumption from the open-loop life estimate.
