Abstract
In one instance, a medical device for harvesting epidermal tissue from a patient includes a first compartment that is mateable with a second, disposable compartment that goes against the skin. The first compartment has a floor that is formed, at least in part, by a first printed circuit board. The ceiling of the second, disposable compartment is formed at least in part by a second printed circuit board that electrically couples with the first printed circuit board when in a mated position. Suction is delivered to the second compartment to pull skin through apertures on the floor of the second compartment to form blisters that are harvested to obtain epidermal tissue. The first compartment remains uncontaminated in use and the second compartment is disposable. Other features are presented; some of which include a thermal sensor in the second compartment for temperature control, clear side walls, and a distributed heating element.
