Patent number: 11986613Abstract: 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.Type: GrantFiled: February 19, 2021Date of Patent: May 21, 2024Assignee: KitoTech Medical, Inc.Inventors: Robert Arman Audell, Ronald J. Berenson, Cheuk Yin Paul Leung

Patent number: 11813143Abstract: 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.Type: GrantFiled: October 1, 2019Date of Patent: November 14, 2023Assignee: KitoTech Medical, Inc.Inventors: Cheuk Yin Paul Leung, Ron Berenson
