Abstract
An implantable medical device system is provided with multiple medical devices implanted in a patient's body and a wireless mesh communication network providing multiple communication pathways between the multiple medical devices. A communication pathway between a first and a second implanted device of the multiple medical devices can comprise one or more of the other implanted multiple medical devices.
Claims16
An implantable medical device system, comprising:
- multiple medical devices implantable in a patient's body, each device comprising a power supply for powering data communication operations, a processor for controlling device functions;
- a memory storing a network rule set and one of a transmitter and a transceiver for wirelessly transmitting data, at least one of the multiple medical devices configured to perform a primary function relating to one of physiological sensing and therapy delivery;
- each of the multiple medical devices having a node status comprising a power status of the power supply of the medical device and an operational workload of the medical device corresponding to a primary function of the medical device;
- and
- a wireless mesh communication network providing multiple communication pathways between the multiple medical devices, data communications on the network controlled by the network rule set;
- the multiple medical devices configured to establish the network rule set in response to the node status of each of the multiple medical devices.
