Abstract
Techniques are provided for use with implantable medical devices or trial medical devices for wirelessly connecting the devices to external instruments such as tablet computers or smartphones. In an example where the medical device is an implantable neurostimulator, the neurostimulator passively detects wireless wake-up signals generated by the external instrument, i.e. the neurostimulator “sniffs” for advertisement signals generated by the external instrument. In response to passive detection of a wake-up signal, the implantable neurostimulator determines if a response is warranted and, if so, the neurostimulator activates its wireless transmission components to transmit an acknowledgement signal to the external instrument so as to complete a wake-up and handshake protocol. In this manner, power consumption within the implantable device (or within a similarly equipped trial medical device) can be reduced compared to devices that would otherwise periodically transmit advertisement signals even when no external mobile instrument is present.
