Abstract
One aspect of the invention provides a glucose monitor having a plurality of tissue piercing elements, each tissue piercing element having a distal opening, a proximal opening and interior space extending between the distal and proximal openings; a sensing area in fluid communication with the proximal openings of the tissue piercing elements; sensing fluid extending from the sensing area into substantially the entire interior space of the tissue piercing elements; and a glucose sensor adapted to detect a concentration of glucose in the sensing fluid within the sensing area. Another aspect of the invention provides a method of in vivo monitoring of an individual'"'"'s interstitial fluid glucose concentration including the following steps: inserting distal ends of a plurality of tissue piercing elements through a stratum corneum area of the individual'"'"'s skin, the tissue piercing elements each having a distal opening, a proximal opening, an interior space extending between the distal and proximal openings, and a sensing fluid filling substantially the entire interior space; and sensing a glucose concentration of the sensing fluid.
