Abstract
A lancing device including a drive mechanism with a drive spring and a lancet carrier engaged and driven by the drive spring, and further including a lancet with a sharp lancing tip, wherein the lancet floats relative to the carrier and is decoupled from the drive mechanism during at least a portion of a lancing stroke. In one example embodiment the lancet is held in a sled that floats in the carrier, and in another example embodiment the lancet by itself floats in the carrier.

23. A lancing device comprising:
-
a housing; a sled carrier slidably mounted for translational motion within the housing between a cocked position and an advanced position; a drive spring operable between the housing and the sled carrier to propel the sled carrier from the cocked position to the advanced position; and a lancet sled carried by the sled carrier between the cocked position and the advanced position and operatively coupled thereby with the drive spring, the lancet sled decoupling from operative engagement with the drive spring as the sled carrier reaches its advanced position and continuing under inertial propulsion into an extended position for lancing. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30)

31. A lancing device comprising:
-
a carriage defining an axial bore extending at least partially therethrough, the carriage being translationally mounted within a housing to slide between a cocked position and an advanced position; a drive spring for propelling the carriage between the cocked position and the advanced position; and a lancet sled slidably mounted within the axial bore of the carriage, wherein the lancet sled is positioned in a retracted position in the axial bore when the carriage is in the cocked position and is released to move to an extended position in the axial bore when the carriage is in the advanced position. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39)

40. A lancing device comprising:
-
a drive mechanism comprising a drive spring and a carrier driven between a cocked position and an advanced position by the drive spring; and a lancet that is operatively coupled to the drive spring via the carrier during a first portion of a lancing stroke, and that is decoupled from the drive spring to slide relative to the carrier during a second portion of the lancing stroke. - View Dependent Claims (41, 42, 43, 44)
