Abstract
The present disclosure broadly provides applications of communication at ultrasound frequencies to establish transcutaneous data communication between medical devices located on and/or within a body of a patient, including inter alia: features for adjustable implants including data communication, hermetic containment, and torque amplification features.
Claims17
An adjustable implant comprising:
- a first portion configured to be secured to a bone at a first location;
- a second portion configured to telescopically receive the first portion and configured to be secured to a bone at a second location;
- an actuator configured to move the first portion relative to the second portion;
- an ultrasonic transducer operably coupled to the actuator and configured to communicate with an external transceiver using ultrasound signals;
- a container having a hermetic seal containing the actuator therein;
- and
- wherein the container further comprises a magnetic coupling having a first magnet rotatably coupled to the actuator and disposed within the container, and a second magnet disposed outside the container configured to magnetically couple to and rotate with the first magnet wherein a rotation of the first magnet rotates the second magnet.

An adjustable implant comprising:
- a rod configured to be secured to a bone at a first location;
- a housing configured to telescopically receive the rod and configured to be secured to a bone at a second location;
- an actuator disposed in the housing configured to move the rod relative to the housing;
- an ultrasonic transducer operably coupled to th;e actuator and configured to communicate with an external transceiver using ultrasound waves
- a power storage device and a container configured to seal one or more of the actuator and the power storage device therein;
- and
- wherein the container comprises a magnetic coupling configured to transfer torque out of the container.
