Pacemaker event queue to control device processor operating power
First Claim
1. An implantable medical device having at least one integrated circuit comprising:
- a memory comprising for storing event data associated with one or more received events;
a control unit comprising for processing the event data;
an interrupt module comprising for controlling transfer of the event data to the control unit; and
a power supply comprising for delivering power to the control unit at a first power level and a second power level, wherein one of the first power level and the second power level are delivered in response to a control signal generated by the interrupt module, andwherein the interrupt module is configured to generate the control signal for controlling the delivery of the first power level and the second power level and the generating of the control signal is triggered by transfer of the event data.

Abstract
In the present disclosure, conservation of an implantable medical device power supply of is facilitated by controlling the power consumption of the device'"'"'s processing component. The power supplied to the processing component is controlled to enable processing of received events as a function of predetermined criteria rather than the actual occurrence of the events which is frequent, but irregular. Accordingly, the need for the processing component to start and stop (and thereby be fully powered on each start) with receipt of each event is obviated thereby maintaining the power consumption of the processing component and increasing longevity of the device. Event data associated with received events is stored in an event queue and subsequently retrieved and transmitted for processing based on predetermined criteria. The power supplied during an idle state of the processing component may be reduced in relation to the power supplied during a wake up state.
