Abstract
A skin grafting system having a handheld device, a cartridge, and a device shield. The handheld device includes a device housing forming an interior that secures a drive system. The cartridge includes a plurality of hollow microneedles surrounded by a peripheral housing and is configured to be operated by the drive system to extend and retract past the peripheral housing into a subject to harvest tissue during a skin grafting process. The device shield is formed of a polymer extending from an interior opening to an exterior edge, the interior opening sized to extend about the peripheral housing to positon the exterior edge over the device housing to control ingress of fluids into the interior of the device housing from fluid about the peripheral housing of the cartridge during the skin grafting process performed using the skin grafting system.
