Abstract
A multiple use analyte sensing assembly that includes a long, thin conductor. A plurality of sensing sites are spaced along the conductor and each sensing site includes a membrane system adapted to create a current when placed into contact with body fluid containing the analyte. The assembly also includes a housing, having an aperture, an uptake spool and a payout spool, the conductor being wrapped about the payout spool before the sensing assembly is used. A sensor positioning actuator turns the uptake spool to move each sensing site, in sequence, to the housing aperture and then to the uptake spool. The assembly also includes a skin broaching assembly, having a multiplicity of lancets and a lancet positioning actuator adapted to move each lancet to the aperture. In addition, a lancet use actuator is adapted to move each lancet at least partially through the aperture and then back again.
