Abstract

Claims (29)

1 . 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.

2 . The adjustable implant of claim 1 , wherein a rotation of the second magnet is configured to move the first portion relative to the second portion.

3 . The adjustable implant of claim 1 , the ultrasonic transducer comprising a hollow piezoelectric transducer.

4 . The adjustable implant of claim 1 , the actuator comprising an electric motor.

5 . The adjustable implant of claim 1 , further comprising a power storage device.

6 . The adjustable implant of claim 5 , wherein the power storage device is charged using electrical energy harvested from an ultrasonic signal.

7 . The adjustable implant of claim 1 , comprising a controller operably connected to one or more of the ultrasonic transducer and the actuator.

8 . The adjustable implant of claim 7 , wherein the controller is configured to receive adjustment instructions via the ultrasonic transducer and actuate the actuator according to the adjustment instructions.

9 . The adjustable implant of claim 8 , wherein the controller is configured to communicate data to the external transceiver using ultrasound signals.

10 . 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.

11 . The adjustable implant of claim 10 , the actuator comprising an electric motor.

12 . The adjustable implant of claim 10 , wherein the power storage device is configured to be charged using electrical energy from an ultrasound signal.

13 . The adjustable implant of claim 10 , comprising a controller operably connected to at least one of the ultrasonic transducer and the actuator.

14 . The adjustable implant of claim 13 , wherein the controller is configured to receive adjustment instructions via the ultrasonic transducer and actuate the actuator according to the adjustment instructions.

15 . The adjustable implant of claim 13 , wherein the controller is configured to communicate data associated with the actuator to the external transceiver using ultrasound waves.

16 . The adjustable implant of claim 10 , comprising a gear housing having at least one planetary gearset.

17 . The adjustable implant of claim 16 , comprising a floating ring gear.
