  • Patent number: 11400258
    Abstract: A sutureless chest tube adhesion assembly configured to quickly and easily anchor a chest tube is described. The assembly generally comprises a notched flexible substrate adapted to adhere to human skin 415. A chest tube incision in a notched region of the substrate provides an entry point for the chest tube which is anchored to the substrate by way of an intermediate flexible membrane that covers and adheres to the chest tube and substrate. The intermediate flexible membrane has a matching notched region adapted to accommodate the chest tube. The chest tube and incision are adapted to be covered by a transparent cover sheet which covers and adheres to a portion of the substrate, the intermediate flexible membrane and to a portion of the human skin 415.

    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.

  • Patent number: 10653823
    Abstract: A composite wound dressing apparatus promotes healing of a wound via the use of a micropump system. The micropump system includes a micropump that applies a subatmospheric pressure to the wound to effectively draw wound fluid or exudate away from the wound bed, or deliver fluids to the wound bed, without the need for a cumbersome external pressure (e.g. vacuum) source. Hence, the wound dressing and micropump system is portable which allows the patient mobility that is unavailable when an external vacuum source is used.

  • Patent number: 9035122
    Abstract: A wound dressing including a hydrophilic layer and a hydrophobic layer is described. The hydrophilic layer absorbs exudate from a wound and the hydrophobic layer absorbs the exudate from the hydrophilic layer and traps the exudate. Because the hydrophilic layer is used adjacent to the wound, the exudate is readily absorbed thereby reducing the risk of maceration and infection of the wound tissue by the exudate. The hydrophobic layer receives the absorbed exudate from the hydrophilic layer and traps the exudate through an interaction that in turn prevents lateral diffusion of the exudate through the bandage to healthy portions of the skin. The hydrophilic and hydrophobic layers are fabricated from polymer fibers that can be spun to include components that facilitate wound healing, such as poly(hexamethylene biguanide) and/or hyaluronic acid.

  • Patent number: 9000251
    Abstract: A wound dressing is made of multiple layers and includes a collection chamber that is in fluid communication with a drainage channel. When applied over a wound, the wound dressing provides protection for the wound while allowing air and fluids to evacuate from the wound through the collection chamber and out through the drainage channel. The wound dressing can include a valve that restricts air and fluids from entering the wound, which is beneficial for treating pneumothorax.

  • Patent number: 8945030
    Abstract: Apparatuses and methods for treating a wound by applying reduced or negative pressure to the wound can include a wound cover, a fluid collection container, a vacuum pump, an inflation pump, and one or more conduits. The wound cover can be configured to move between at least a relatively rigid, generally raised position and a relatively flexible, generally collapsed position according to a predetermined program or in response to input from a user or one of more sensors. In some embodiments, the wound cover can be configured to move between at least the relatively rigid, generally raised position and the relatively flexible, generally collapsed position by adjusting the air pressure in one or more channels in the wound cover or by adjusting or by adjusting the length of piezoelectric or other length changing material supported by the wound cover.
