Method and device for sub-dermal tissue treatment
First Claim
1. A system for non-invasive lysis of sub-dermal tissue by means of focused ultrasonic energy, comprising:
- (i) a source of ultrasonic energy adapted to operate in continuous wave mode and to focus ultrasonic energy in a focal zone within said sub-dermal tissue, said ultrasonic energy being adapted to induce tissue cavitation in said focal zone;
(ii) means for continuous displacement of said source over the skin surface; and
(iii) means for determining a safe speed for said continuous displacement, said safe speed allowing to obtain said cavitation while avoiding thermal damage of said tissue.

Abstract
System and method for non-invasive lysis of sub-dermal tissue by means of focused ultrasonic energy, the system comprising: a source of ultrasonic energy adapted to operate in continuous wave mode and to focus ultrasonic energy in a focal zone within the sub-dermal tissue, the ultrasonic energy being adapted to induce tissue cavitation in the focal zone; means for continuous displacement of the source over the skin surface; and means for determining a safe speed for the displacement, the safe speed allowing to avoid thermal tissue damage. The source of ultrasonic energy is accommodated in a hand-held applicator including a wheeled traction system powered by an electric drive.

20. A method for non-invasive lysis of sub-dermal tissue, said method comprising:
-
(i) Providing a source of continuous-wave ultrasonic energy with parameters adapted to induce tissue cavitation;
(ii) Determining a safe speed for continuous displacement of said source over the skin surface, such that said safe speed is slow enough to allow cavitation in the focus zone but fast enough to avoid thermal tissue damage;
(iii) Applying said source to the skin surface and focusing the ultrasonic energy in a focal zone at a predetermined depth under the skin; and
(iv) Displacing said source over the skin surface maintaining said safe speed. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29)
