Abstract
The present disclosure provides implants, sensor modules, networks, and methods configured to establish transcutaneous power and transcutaneous bidirectional data communication using ultrasound signals between two or more medical devices located on and within a body of a patient.
Claims17
An apparatus comprising:
- a sensor module comprising:
- an encapsulation hermetically sealing the sensor module;
- an ultrasonic transducer;
- a power store;
- one or more sensors;
- a controller operatively coupled to the ultrasonic transducer and the one or more sensors;
- and
- a charging circuit operably connected to the power storage device and the ultrasonic transducer such that the power storage device receives power from the ultrasonic transducer;
- and
- an implantable medical device having an interior portion, wherein at least a portion of the sensor module is disposed within the interior portion of the implantable medical device,
- wherein the controller is configured such that upon receipt of ultrasound waves at the ultrasonic transducer corresponding to a particular modulated signal, the controller modifies an electrical switch to cause powering or powering down of the implantable medical device.
8 more elements
A system comprising:
- a host device,
- first and second sensor modules, each comprising:
- an encapsulation hermetically sealing the respective sensor module;
- an ultrasonic transducer;
- a power store;
- one or more sensors;
- a controller operatively coupled to the ultrasonic transducer and the one or more sensors;
- and
- a charging circuit operably connected to the power storage device and the ultrasonic transducer such that the power storage device receives power from the ultrasonic transducer;
- a first implantable medical device having a first interior portion, wherein at least a portion of the first sensor module is disposed within the first interior portion;
- and
- a second implantable medical device having a second interior portion, wherein at least a portion of the second sensor module is disposed within the second interior portion,
- wherein the first and second sensor modules are configured to communicate between each other using respective ultrasonic transducers to establish an ad hoc mesh network across the first and second implantable medical devices using ultrasound signals,
- wherein the first and second implantable medical devices are client implants, and
- wherein the host device is configured to actuate one or more of the client implants.
