Abstract
The present invention includes methods and apparatus for continuous glucose monitoring of a patient. In one aspect a glucose monitor includes a plurality of substantially cylindrical tissue piercing elements adapted to pierce the stratum corneum and enter the epidermis, allowing for the diffusion of glucose from the interstitial fluid into the glucose monitors described herein. In another aspect of the invention, a glucose monitor includes a deformed substrate layer defining a plurality of tissue piercing elements.
