  • Patent number: 11839402
    Abstract: Embodiments include devices and methods configured to fractionally resect skin and/or fat. Fractional resection is applied as a stand-alone procedure in anatomical areas that are off-limits to conventional plastic surgery due to the poor tradeoff between the visibility of the incisional scar and amount of enhancement obtained. Fractional resection is also applied as an adjunct to established plastic surgery procedures such as liposuction, and is employed to significantly reduce the length of incisions required for a particular application. The shortening of incisions has application in both the aesthetic and reconstructive realms of plastic surgery.

  • Patent number: 11751903
    Abstract: Embodiments include a method comprising determining histological factors at a target site of a subject, and determining parameters of a fractional resection based on the histological factors. The parameters include dimensionality of a fractional field, orientation of the fractional field, resection depth, and a vector of directed closure. The method includes configuring a cannula assembly for the fractional resection that includes a procedure to generate a fractional field at the target site by fractionally resecting tissue according to the parameters. The fractional resection includes applying a cannula array of the cannula assembly to the target site, and rotating at least one cannula of the cannula array to circumferentially incise and remove a plurality of skin plugs in the fractional field.

  • Patent number: 11090473
    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.
