Abstract

Devices and methods for treating human cranial hair loss using extracorporeal acoustic shock waves are disclosed. The shock wave device optionally includes a proximal surface, a plurality of shock wave generators disposed on the surface, and a coupling assembly configured to transmit shock waves to a user'"'"'s scalp.

Claims

1. A method for applying treatment to a user'"'"'s scalp, comprising:

positioning a coupling assembly of an extracorporeal shock wave apparatus to contact an area of the user'"'"'s scalp, wherein the coupling assembly comprises shock wave couplant and a deformable sac configured to be in contact with the area of the user'"'"'s scalp;

generating, using a plurality of shock wave generators of the extracorporeal shock wave apparatus, a plurality of shock waves,

wherein the plurality of shock wave generators are disposed on a first surface of a housing of the extracorporeal shock wave apparatus and are sandwiched by the coupling assembly and the first surface,

wherein the first surface of the housing is flat or concave in the same direction as the user'"'"'s scalp, and

wherein the plurality of shock wave generators are in contact with the shock wave couplant of the coupling assembly; and

transmitting, using the coupling assembly disposed over and covering the plurality of shock wave generators, the plurality of shock waves to the user'"'"'s scalp via the shock wave couplant.

2. The method in claim 1, wherein the first surface has at least one geometric real focal point or focal volume, and the coupling assembly is configured to transmit the plurality of shock waves to the user'"'"'s scalp before the plurality of shock waves reach the at least one focal point.

3. The method in claim 1, wherein the plurality of shock wave generators comprising a plurality of piezoelectric ceramic tiles, the method further comprising:

transmitting an electrical signal to the plurality of piezoelectric ceramic tiles; and

causing the plurality of piezoelectric ceramic tiles to momentarily deform in response to the electrical signal.

4. The method in claim 1, wherein the plurality of shock wave generators comprising a plurality of conductive wire segments sandwiching the first surface of the housing and a conductive film, the method further comprising:

transmitting an electrical signal through the plurality of wire segments; and

causing the conductive film to momentarily deform in response to an electromagnetic field generated by the electrical signal in the plurality of conductive wire segments.

5. The method in claim 1, wherein the coupling assembly further comprises a flexible layer configured to contact the scalp.

6. The method in claim 1, wherein the deformable sac is configured to contain a volume of liquid, the method further comprising:

filling the sac with a volume of liquid.

7. The method in claim 6, wherein the apparatus further comprising a control and power supply unit configured to connect electrically to the plurality of shock wave generators, the method further comprising:

controlling a group of the plurality of shock wave generators using the power supply and control unit; and

filling the sac with the volume of liquid using the control and power supply unit.

8. The method in claim 7, wherein controlling a group of the plurality of shock wave generators using the power supply and control unit further comprising:

generating, at the power supply and control unit, a pulsed electrical signal; and

transmitting the pulsed signal to a group of the plurality of shock wave generators.
