Abstract

Embodiments of a dermatological cosmetic treatment and imaging system and method can include use of a hand wand and a removable transducer module having an ultrasound transducer. The system can include a control module that is coupled to the hand wand and has a graphical user interface for controlling the removable transducer module, and an interface coupling the hand wand to the control module. In some embodiments, the cosmetic treatment system may be used in cosmetic procedures on at least a portion of a face, head, neck, body, and/or other part of a patient for a face lift, a brow lift, a chin lift, an eye treatment, a wrinkle reduction, a scar reduction, a burn treatment, a tattoo removal, a skin tightening, a vein reduction, a treatment on a sweat gland, a treatment of hyperhidrosis, a sun spot removal, a fat treatment, a vaginal rejuvenation, and/or an acne treatment.

Claims

1. A method of performing a cosmetic procedure, the method comprising:

coupling a transducer module with an ultrasonic probe;

wherein said ultrasonic probe comprises a first switch to control acoustic imaging;

wherein said ultrasonic probe comprises a second switch to control acoustic therapy for causing a plurality of individual thermal lesions;

wherein said ultrasonic probe comprises a movement mechanism to provide desired spacing between the individual thermal lesions;

contacting said transducer module with a subject'"'"'s skin surface;

activating said first switch on said hand controller to acoustically image, with said transducer module, a region below said skin surface; and

activating said second switch on said hand controller to acoustically treat, with said transducer module, said region below said skin surface in a desired sequence of individual thermal lesions that is controlled by said movement mechanism.

2. The method according to claim 1, further comprising:

collecting data based on said acoustic imaging; and

performing said acoustic therapy based on said data.

3. The method according to claim 1, wherein said acoustic therapy comprises tightening the region below said skin surface to produce a desired cosmetic effect on the face, head, neck area or body of said subject.

4. The method according to claim 1, further comprising:

decoupling said transducer module from said ultrasonic probe; and

coupling a second transducer module to said ultrasonic probe,

wherein said second transducer module applies a second acoustic therapy that is different than the acoustic therapy that is initially applied, and

wherein said second transducer module applies a second acoustic therapy at a different depth below the skin surface.

5. The method according to claim 1, further comprising:

decoupling said transducer module from said ultrasonic probe; and

coupling a second transducer module to said ultrasonic probe,

wherein said second transducer module applies a second acoustic therapy that is different than the acoustic therapy that is initially applied, and

wherein said second transducer module applies a second acoustic therapy at a different frequency.

6. The method according to claim 1, further comprising:

ultrasonically imaging a target region on said subject with the transducer module; and

ultrasonically treating said target region on said subject with said transducer module at a tissue depth, wherein said treatment comprises multiple treatment lines across the target region that are automatically selected by said movement mechanism.

7. The method according to claim 1, further comprising:

applying acoustic therapy at a first layer of tissue and at a second layer of tissue,

wherein the first layer of tissue and the second layer of tissue are located at different depths below a single region of a skin surface to increase the overall volume of tissue treated below said skin surface, thereby providing an enhanced overall cosmetic result.

8. The method according to claim 1, wherein said cosmetic procedure is at least one of a face lift, a brow lift, a chin lift, an eye treatment, a wrinkle reduction, a scar reduction, a burn treatment, a tattoo removal, a skin tightening, a vein removal, a vein reduction, a treatment on a sweat gland, a treatment of hyperhidrosis, a sun spot removal, a fat treatment, a vaginal rejuvenation, and an acne treatment.

9. The method according to claim 1, wherein contacting said transducer module with the subject'"'"'s skin surface comprises positioning at least a portion of the transducer module to directly contact the skin surface.

10. The method according to claim 1, wherein contacting said transducer module with the subject'"'"'s skin surface comprises positioning at least a portion of the transducer module to indirectly contact the skin surface.

11. A method of performing a cosmetic procedure on a subject using an aesthetic imaging and treatment system, wherein said method comprises:

ultrasonically imaging a target tissue region under a skin surface of said subject with a removable transducer module, the removable transducer module interchangeably coupled to a hand wand; and

ultrasonically treating said target tissue region on said subject with said first transducer module at a first tissue depth, wherein said treatment comprises at least one treatment comprising a linear sequence of individual ablative lesions across the target tissue region, the sequence of individual ablative lesions controlled by a movement mechanism in the hand wand.

12. The method according to claim 11, wherein the movement mechanism is configured to be programmed to provide variable spacing between said individual thermal lesions.
