Abstract
A device for monitoring, sampling or delivering a substance to the skin of a patient includes a medical device and a stretching device for stretching the skin to enhance the contact by the medical device. The medical device generally includes at least a skin penetrating member, such as a cannula. The cannula can be a single needle or an array of microneedles. The method for monitoring, sampling or delivering a substance positions the device on the skin and presses downwardly on the device causing the stretching device to stretch the skin in a target area of the skin penetrating member to enable uniform penetration of the skin. The uniform penetration provides for a more uniform monitoring, sampling or delivery of the substance to the patient.
