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.

First claim

What is claimed is:

1. A deformity treatment system, comprising:
a control module having a transceiver configured to send and receive data; and
an adjustable implant, the adjustable implant includes a driver configured to adjust the adjustable implant; wherein the adjustable implant includes a first magnetic element;
wherein the control module is implantable separately from the adjustable implant and includes a second magnetic element; and
wherein the adjustable implant is adjusted in accordance with treatment instructions using a magnetic field generated from the second magnetic element in the control module to move the first magnetic element in the adjustable implant.

2. The system of claim 1 , wherein the driver includes the first magnetic element.

3. The system of claim 2 , wherein the driver includes an actuator configured to rotate the magnetic element.

4. The system of claim 3 , wherein the first magnetic element includes a rotatable permanent magnet.

5. The system of claim 3 , wherein the actuator includes an electric motor.

6. The system of claim 1 , wherein the transceiver includes an ultrasonic transducer configured to send and receive ultrasound signals.

7. The system of claim 1 , further comprising:
a controller operably connected to one or more of the transceiver and the driver.

8. The system of claim 7 , wherein the controller includes a microcontroller.

9. The system of claim 1 , wherein the control module is configured for subcutaneous placement within a body of a patient.

10. The system of claim 1 , wherein the control module is configured to be secured to a bone of a patient.

11. A system for treating a deformity, comprising:
an adjustable implant;
a control module implantable separately from the adjustable implant, the control module having a magnetic element; and
an external transceiver;
wherein the adjustable implant includes a rotatable permanent magnet,
wherein the rotatable permanent magnet of the adjustable implant is configured to magnetically couple with the magnetic element of the control module,
wherein the external transceiver is configured to transmit treatment instructions to the control module, and wherein the control module is configured to adjust the adjustable implant in accordance with the treatment instructions, and
wherein rotation of the rotatable permanent magnet is configured to change a dimension of the adjustable implant.

12. The system of claim 11 , wherein the control module includes:
a transceiver configured to communicate with the external transceiver; and
a driver configured to adjust an adjustable implant.

13. The system of claim 12 , wherein the driver includes an actuator configured to rotate the rotatable permanent magnet of the adjustable implant.

14. The system of claim 11 , wherein the external transceiver is configured to communication with the control module using an ultrasound signal.

15. The system of claim 11 , wherein the external transceiver is configured to communicate with the control module using a radio frequency signal.

16. The system of claim 11 , wherein the control module is configured to determine an amount of adjustment of the adjustable implant and communicate the amount of adjustment to the external transceiver.

17. The system of claim 11 , wherein the control module is configured for subcutaneous placement and configured to be secured to a bone of a patient.

18. A method for treating a deformity, comprising:
providing an adjustable implant within an intramedullary cavity of a bone, wherein the adjustable implant includes a first magnetic element;
securing a control module to the bone, the control module being implanted separately from the adjustable implant and having a second magnetic element; and
communicating treatment instructions to the control module using an external transceiver; and
adjusting the adjustable implant in accordance with the treatment instructions using a magnetic field generated from the second magnetic element in the control module to move the first magnetic element in the adjustable implant.
