INSERTION SETS WITH MICRO-PIERCING MEMBERS FOR USE WITH MEDICAL DEVICES AND METHODS OF USING THE SAME

摘要

An insertion set for essentially painless insertion through tissue includes a substrate and at least one micro-piercing member. The at least one micro- piercing member is coupled to the substrate to form a patch. In addition, th e at least one micro-piercing member has a predetermined length to pierce the material to a predetermined depth to interact with the tissue. In particular embodiments, the insertion set also includes a control structure within the insertion set for controlling the flow of fluid relative to the substrate an d the at least one micro-piercing member of the insertion set. In addition, th e insertion set may include or utilize methods or structures for maintaining t he insertion set on the tissue for a predetermined period of time. Preferably, the predetermined length of the at least one micro-piercing member is long enough to pierce the tissue, and yet short enough to avoid contacting the nerves in the tissue. The insertion set may also include a light controlling structure within the insertion set for controlling the entry of light relati ve to the substrate and the at least one micro-piercing member of the insertion set. Some types of insertion sets may include a fluorescent analyte detectio n compound (or other detection compound) to detect the level of an analyte in the tissue, while other insertion sets are an infusion set for infusing a liquid into the tissue.
