Combination ultrasound-phototherapy transducer
View Patent ↗A soundhead of a treatment device is provided that enables a volume of tissue located beneath the soundhead to simultaneously receive ultrasound and light stimulation. According to one embodiment, the soundhead includes an ultrasound transducer, a light source, and a faceplate extending across a face of the transducer for providing a tissue contacting and ultrasound energy coupling surface of the soundhead. The faceplate is transparent or translucent to the light generated by the light source. Alternate embodiments including externally mounted light sources are also disclosed.
1. A method for treating tissue, the method comprising:
contacting a portion of a treatment device with the tissue;
generating ultrasound with the treatment device;
generating light with the treatment device;
transmitting the ultrasound and the light from the portion of the treatment device in contact with the tissue; and
performing a coincident treatment of the tissue with both the ultrasound and the light generated by the treatment device to provide a therapeutic effect to the tissue.
2. The method of claim 1 wherein the tissue includes a wound, and the therapeutic effect is effective to repair the wound.
3. The method of claim 1 wherein the tissue includes a surgical wound, and the therapeutic effect is effective to repair the surgical wound.
4. The method of claim 1 wherein the tissue comprises a non-melanoma skin cancer that receives coincident treatment with the ultrasound and the light.
5. The method of claim 1 wherein the tissue comprises acne that receives coincident treatment with the ultrasound and the light.
6. The method of claim 1 wherein the tissue is photorejuvenated by receiving coincident treatment with the ultrasound and the light.
7. The method of claim 1 wherein a permeability of the tissue is changed.
8. The method of claim 7 further comprising:
topically applying a drug before performing coincident treatment of the tissue with the ultrasound and the light.
9. The method of claim 1 , wherein the tissue to be treated includes an outermost surface, and contacting the portion of the treatment device with the tissue further comprises:
contacting the portion of the treatment device with the outermost surface of the tissue so as to position the treatment device at an area where the tissue is to be treated.
10. The method of claim 1 , wherein the ultrasound generated by the treatment device is therapeutic ultrasound, and the light generated by the treatment device is therapeutic light.
11. The method of claim 1 , wherein the portion of the treatment device contacted with the tissue is an active portion of the treatment device.
