Abstract: A lancing device and lancet are provided with depth-control, lancet ejection, and/or guidance mechanisms. The depth-control mechanism includes a dial rotationally mounted at a distal end of the housing of the lancing device, the dial being coupled to a linkage whereby rotation of the dial imparts translational movement to a stop surface of the linkage to limit the stroke of the lancet and thereby control lancing penetration depth. The ejection mechanism includes an ejector that is advanced into contact with a transversely flared flange of the lancet to discharge the lancet from the lancing device. The guidance mechanism includes an inner guidance housing for restricting out-of-axis movement of a lancet carrier.

Abstract: Improved lancet configurations and protective lancet endcap configurations are disclosed. In example forms, one or more flexing cantilevers project from the lancet body for coupling with a cooperating receiver of a lancing device. A gripping handle extends from a sterility cap for ease of removal from and replacement over the lancet tip. A lancet body has a smoothly curved wave contour with at least one crest and at least one trough for engagement with a cooperating receiver of a lancing device.

Abstract: A guidance mechanism for a lancing device. The guidance mechanism includes a piston having a shaft, a plurality of wings or fins extending from the shaft, a plurality of sliding engagement structures, and a lancet holder; and a chassis having a body, a plurality of longitudinal slits or cutouts, a plurality of elongated engagement structures, and an end aperture. The piston slides within the chassis, and the wings/fins engage within the slits/cutouts, allowing for linear longitudinal guidance of the piston within the chassis.

Abstract: A system and method for assembling a lancing device, and a lancing device fabricated according to such a system or method. A rotating disk is applied to a spring component and/or to a carrier component of the lancing device to mount the spring onto the carrier component.

Abstract: A lancet for use with a lancing device, the lancet having a body with releasable engagement features for engagement with a cooperating portion of a lancing device, a sharp needle, and a removable endcap. A coupling portion of the lancet has a non-circular profile. The endcap includes a receptacle for covering the sharp lancet tip after use, and a sheath portion with relief openings to reduce bending of the needle during manufacture or during removal of the endcap.

The guidance mechanism includes an inner guidance housing for restricting out-of-axis movement of a lancet carrier.
