Abstract

Ultrasound stimulation devices and related techniques are disclosed. An ultrasound transducer for generating ultrasound energy is carried by a transducer housing that seals the transducer and may also include a positioning element for positioning the transducer proximate an application area to which generated ultrasound energy is to be applied. The transducer housing may also carry such components as a battery, a wireless receiver, and a controller. The same housing or a separate sensor housing may include an ultrasound sensor that provides feedback to the ultrasound transducer or its controller, illustratively through a wireless transmitter.

Claims

1. A device comprising:

a miniaturized ultrasound transducer operable to generate ultrasound energy;

a miniaturized biocompatible transducer housing for carrying the ultrasound transducer;

a miniaturized extra-oral transducer positioning element operable to position the ultrasound transducer proximate to an application area to which the generated ultrasound energy is to be applied for ultrasound dental treatment, jaw joint treatment, or stimulation of jaw growth;

a miniaturized intra-oral ultrasound sensor operable to sense the ultrasound energy generated by the ultrasound transducer, and to provide a feedback signal to a miniaturized intra-oral controller disposed in the transducer housing and operatively coupled to the ultrasound transducer, the controller being operable to control an intensity of the ultrasound energy generated by the ultrasound transducer;

a miniaturized intra-oral biocompatible sensor housing for carrying the ultrasound sensor;

a miniaturized intra-oral tooth-root sensor positioning element operable to position the ultrasound sensor adjacent and along a length of a tooth root and gum tissue, the tooth-root sensor positioning element operable to position the ultrasound sensor in a manner which separates the ultrasound sensor from the transducer with cheek tissue or cheek tissue and the tooth root and gum tissue, to which the generated ultrasound energy is to be applied for ultrasound dental treatment;

wherein the extra-oral transducer positioning element comprises a releasable mounting portion configured for temporarily mounting the transducer housing to skin covering a jaw joint or cheek; and

wherein the sensor positioning element comprises a releasable mounting portion configured for temporarily mounting the sensor housing to a tooth or other intra-oral structure.

2. The device of claim 1, wherein the transducer housing comprises:

a transducer portion for carrying the ultrasound transducer; and

a positioning portion comprising the transducer positioning element.

3. The device of claim 1, wherein the ultrasound transducer comprises a low intensity pulsed ultrasound (LIPUS) transducer.

4. The device of claim 1, further comprising:

a battery disposed in the miniaturized biocompatible transducer housing and operatively coupled to the miniaturized ultrasound transducer.

5. The device of claim 1, wherein the sensor positioning element comprises one of:

an element for attachment to an orthodontic bracket that is fastened to the tooth or other intra-oral structure; and

an element for attachment to the tooth or other intra-oral structure.

6. The device of claim 1, further comprising:

a miniaturized intra-oral wireless transmitter operatively coupled to the ultrasound sensor; and

a miniaturized wireless receiver disposed in the transducer housing and operatively coupled to the controller; and

wherein the feedback signal is generated by the ultrasound sensor and is transmitted by the wireless transmitter and wherein the feedback signal is received by the controller through the wireless receiver.

7. The device of claim 6, wherein the wireless transmitter and the wireless receiver comprise an ultra-wideband (UWB) transmitter and a UWB receiver, respectively.

8. The device of claim 1, wherein the transducer positioning element comprises the sensor positioning element.

9. The device of claim 1, wherein the sensor positioning element comprises a plate structured for retention by a portion of an oral cavity.

10. The device of claim 1, wherein the transducer positioning element comprises a rubber suction cup.

11. The device of claim 1, wherein the transducer positioning element comprises a head apparatus.
