摘要： An attachment device used to attach appliances to tissue can incorporate microstructures. A medical device system can comprise a coupling device comprising a base layer, a coupling attached to an air side of the base layer, a microstructure attached to a skin side of the base layer and a patient interaction feature, and an appliance comprising a structure mounted to the coupling to interface with the patient interaction feature. An appliance device comprises a base layer, an appliance structure attached to an air side of the base layer, and a microstructure attached to a skin side of the base layer. An appliance attachment system comprises an appliance, a first component comprising an adhesive backing containing microstructures that are configured to attach to skin, and a second component configured to attach the appliance to the first component.

摘要： A wound cover device can comprise 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 comprise 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.

摘要： 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.

摘要： Systems, apparatus, and methods related to wound closure devices comprising one or more microstructures are described herein. In some embodiments, the wound closure devices include a backing and a microstructure array. The microstructure array may include a first portion, a second portion, and a bridge portion. The first portion and the second portion each include one or more microstructures configured to penetrate tissue. Additionally, the first portion and the second portion each include one or more expandable portions such that the wound closure device is configured to expand in length. The wound closure device is configured to grip tissue surrounding a wound to either close the wound or secure the tissue in place.
