Abstract: A medical device includes a base having a first surface to be secured to a patient's skin. A first insertable member has a length portion extending from the first surface of the base for insertion. A second insertable member has a length portion extending from the first surface of the base for insertion through the patient's skin. The first insertable member includes a sensor member for sensing a biological condition, and the second insertable member includes an infusion cannula for infusing an infusion media. The distal end of the first insertable member and the distal end of the second insertable member are spaced apart by a first distance of at least 5.0 mm, for reducing interference of the infusion media from the infusion cannula with an operation of the sensor member.

The plurality of conduits include a fluid delivery conduit configured to facilitate a fluidic connection between a fluid source and the anatomy of the user, and one or more conduits configured to accommodate a plurality of electrodes for determining a physiological characteristic of the user.

Abstract: An insertion set system includes a base configured to be secured to a patient, and a flexible tubing on the base. The flexible tubing has a distal end portion forming a cannula to be inserted into the patient. An inserter having a needle is received by the base. The needle has a channel in which the distal end portion of the flexible tubing is received. The needle is able to slide relative to the flexible tubing, to selectively withdraw the needle off of the distal end portion of the flexible tubing. The base may include a passage for fluid flow arranged transverse to the axial dimension of the distal end portion of the flexible tubing.

Abstract: Disclosed is a medical device component for delivering medication fluid to a patient. The medical device component includes a fluid infusion device to regulate delivery of medication fluid, a body-mountable base unit, and a top cover assembly that is removably couplable to the base unit and to the fluid infusion device. The base unit includes a cannula to deliver medication fluid under the control of the fluid infusion device, and a physiological analyte sensor to measure a physiological characteristic.
