  • Patent number: 10773064
    Abstract: A new minimally invasive surgical approach is proposed that contemplates a method and apparatus for tightening lax skin without visible scarring via a device in various surgical procedures such as plastic surgery procedures. In some embodiments, the device is a single use disposable instrument. This approach circumvents surgically related scarring and the clinical variability of electromagnetic heating of the skin and performs small multiple pixilated resections of skin as a minimally invasive alternative to large Plastic surgical resections of skin. This approach can also be employed in areas of the body that are currently off limits to plastic surgery due to the visibility of the surgical scar. In addition, the approach can perform a skin grafting operation by harvesting the transected incisions of skin from a tissue site of a donor onto a skin defect site of a recipient with reduced scarring of the patient's donor site.

  • Publication number: 20120283725
    Abstract: A method of creating a tissue effect at a tissue site delivers electromagnetic energy through a skin surface from an electromagnetic energy delivery device coupled to an electromagnetic energy source. At least one of the electromagnetic energy delivery device or electromagnetic energy source includes a memory. A reverse thermal gradient is created through the skin surface to sufficiently heat an underlying tissue site to provide that a temperature of the skin surface is lower than a temperature of the underlying tissue. Information is stored from the memory to facilitate operation of at least one of the electromagnetic energy delivery device or the electromagnetic energy source. Electromagnetic energy is applied through the skin surface to the underlying tissue. A tissue effect is created on at least a portion of the tissue site.

  • Publication number: 20120078141
    Abstract: A new non-invasive approach is proposed that contemplates a method and apparatus to utilize two- or three-dimensional treatment patterns with a reverse thermal gradient to non-invasively heat a subjacent soft tissue structure through an intact tissue surface or an intact surface epithelium for clinical applications. For most clinical applications, an electromagnetic energy source with surface cooling is employed to heat the treatment patterns. Without limitation, the clinical applications include but are not limited to the treatment of post partum vaginal laxity, female incontinence, cervical incompetence with preterm labor, gastro-esophageal reflux, reduction of gastric reservoir capacity (for weight management), sleep apnea, snoring, pain management and the treatment of orthopedic injuries such as joint laxity and tennis elbow.

  • Patent number: 7189230
    Abstract: A method for treating a tissue site couples an energy delivery surface of an electromagnetic energy delivery device with a skin surface. An underlying tissue area beneath the skin surface is created. The cooling creates a reverse thermal gradient, where a temperature of the skin surface is less than a temperature of the underlying tissue area. Energy is delivered from the energy delivery device to the underlying tissue area. The energy delivery modifies the underlying tissue area and decreases irregularities of the skin surface.
