  • Publication number: 20240285921
    Abstract: The present invention relates generally to devices comprising one or more microstructures that are used to relieve, treat or prevent pain. The devices are designed such that they are inserted into the superficial layers of the skin to achieve pain relief. The devices are designed such that the microstructures are able to grasp and secure to the skin. The devices may consist of microstructures in arrays that are attached to a backing to enable the devices to adhere to the skin. Also provided are wound closure systems that comprise one or more microstructure devices along with other components, such as protective covers and therapeutics. A variety of packaging specifications are disclosed, as is a dispenser apparatus configured to enable simple one-handed application of the devices. Methods described herein provide for treatment of pain.

  • Patent number: 11813143
    Abstract: A wound cover device can include a backing, a micro-structure device, and one or more of a wound dressing and a skin replacement layer. The backing can be stretchable. The micro-structure device can include a plurality of fasteners, such as micro-staples, micro-pins, micro-barbs and the like, that can be used to attach the wound cover device to tissue such as skin. The micro-structure device can be stretchable to stretch with the backing. The micro-structure device can be configured such that the fasteners are positioned in a two-dimensional pattern or fill-in an interior portion of the wound dressing or skin replacement layer. The fasteners of the micro-structure device can extend through the wound dressing or skin replacement layer. The micro-structure device can additionally be placed around a perimeter or edge region of the backing.

  • Publication number: 20210325109
    Abstract: Disclosed herein is a novel medical implement drying apparatus and a method for holding and drying certain medical implements during a reprocessing sequence. This is accomplished by forcing air through the apparatus. The apparatus and method disclosed herein is useful for many medical implements having a hollow casing. The medical implement drying apparatus is particularly well suited for use with a drying cabinet containing one or more of the medical implements during the drying process which will facilitate drying of the exterior of each medical implement, while the disclosed apparatus removes water and water vapor from the interior of each medical implement. Specialized holders, racks, and drying gas pumping systems are also disclosed.
