  • Patent number: 10485575
    Abstract: Systems, instruments, and methods are described in which an apparatus comprises a housing including a scalpet device. The scalpet device includes a scalpet array that includes scalpets arranged in a pattern. The scalpets are deployable from the housing to generate incised skin pixels at a target site. The housing is positioned and the scalpet array is deployed into tissue at the target site. Incised skin pixels are generated when the target site is a donor site, and skin defects are generated when the target site is a recipient site. The incised skin pixels are harvested.

  • Patent number: 10478251
    Abstract: A device includes a catheter section comprising a flexible joint region disposed between a distal end and a proximal end. The device includes a laser fiber disposed within the catheter section. The laser fiber emits laser light at a fiber distal end. The device includes a wire comprising a distal end coupled to the catheter section. The wire is configured to move the distal end of the catheter section from a first position to a second position about the flexible joint region.

  • Patent number: 10368904
    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: 10335190
    Abstract: Systems, instruments, methods, and compositions are described involving removing a portion of the epidermis within a donor site on a subject, and harvesting dermal plugs within the donor site. An injectable filler is formed by mincing the dermal plugs. The injectable filler is configured for injecting into a recipient site on the subject.

  • Patent number: 10335191
    Abstract: Systems, instruments or devices, and methods or procedures are described in which a scalpet array is applied to a target site with the use of a pattern. The scalpet array comprises scalpets positioned on a device. Skin pixels are incised at the target site via application of a load through the scalpet array. A recipient site is prepared by positioning the pattern at the recipient site and applying the scalpet array to generate skin defects. The incised skin pixels are applied at the skin defects of the recipient site.

  • Patent number: 10219827
    Abstract: Pixel array medical devices, systems and methods are described for skin grafting and skin resection procedures. The procedures involve applying a scalpet array to a target skin site. The scalpet array comprises scalpets positioned on an investing plate. Skin pixels are circumferentially incised at a target skin site by applying a load via the scalpet array onto subjacent skin surface that includes the target skin site. Incised skin pixels are captured on an adherent substrate, where the incised skin pixels are extruded through the scalpet array. Bases of incised skin pixels extruded through the scalpet array are then transected.

  • Patent number: 9987473
    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.
