System and method for low power communication between implantable devices

摘要

In accordance with an embodiment, apparatuses and methods are provided for coordinating operation between leadless pacemakers (LPs) located in different chambers of the heart. A method includes configuring a local LP to receive communications from a remote LP through conductive communication over first and second channels, maintaining the first channel active for at least a portion of a time when the second channel is inactive to listen for event messages from the remote LP, detecting an incoming signal at the local LP over the first channel, determining whether the incoming signal received over the first channel corresponds to an LP wakeup notice, when the incoming signal corresponds to the LP wakeup notice, activating the second channel at the local LP, and receiving an event message over the second channel from the remote LP.

主权项

1. A method for coordinating synchronized operation between two or more implantable medical devices (IMDs), the method comprising:
configuring a first IMD to receive communications from a second IMD through conductive communication over first and second channels; maintaining the first channel active for at least a portion of a time when the second channel is inactive to listen for event messages from the second IMD; detecting an incoming signal at the first IMD over the first channel; determining whether the incoming signal received over the first channel corresponds to a message trigger pattern; when the incoming signal corresponds to the message trigger pattern, activating the second channel at the second IMD; and receiving an event message over the second channel from the first IMD using a first receiver of the second IMD.
