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 cosmetically improving the appearance of a region around an eye, the method comprising:

coupling a transducer module with a hand wand,

wherein said hand wand comprises a first switch to control acoustic imaging,

wherein said hand wand comprises a second switch to control acoustic therapy for causing a plurality of individual thermal lesions along a length of up to about 100 mm,

wherein said hand wand comprises a movement mechanism to provide spacing between the individual thermal lesions in a range of about 0.02 mm to about 25 mm;

contacting said transducer module with at least one of a subject'"'"'s upper eyelid, lower eyelid, or a tissue surrounding the upper or lower eyelid;

activating said first switch on said hand controller to acoustically image, with said transducer module, a region below a 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 to affect said subject'"'"'s collagen through tissue coagulation or tightening, thereby improving the cosmetic appearance of a region around said subject'"'"'s eye.

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 at least one of a desired non-invasive blepharoplasty, a reduction in eye laxity, an alteration of the appearance of periorbital lines, or an improvement of skin texture around said subject'"'"'s eye.

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

decoupling said transducer module from said hand wand; and

coupling a second transducer module to said hand wand,

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 hand wand; and

coupling a second transducer module to said hand wand,

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 within a range of about 0.5 mm to about 5 mm, 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 at a tissue depth of about 3 mm and at a second layer of tissue at a tissue depth of about 1.5 mm,

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 appearance of a region around said subject'"'"'s eye.

8. 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.

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 indirectly contact the skin surface.

10. A method of performing a cosmetic eyelift 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 at least one of a subject'"'"'s upper eyelid, lower eyelid, or a tissue surrounding the upper or lower eyelid with a removable transducer module, the removable transducer module interchangeably coupled to a hand wand; and

ultrasonically treating said target tissue region on said at least one of said upper eyelid, lower eyelid, or a tissue surrounding the upper or lower eyelid with said first transducer module at a first tissue depth of less than 5 mm, wherein said treatment comprises at least one treatment comprising a 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 to affect said subject'"'"'s collagen through tissue coagulation or tightening to facilitate a lifting of a region around said subject'"'"'s eye.
