1. A lancing device, for use with a lancet for lancing body tissue to result in a wound for bleeding, the lancing device comprising:
- (1) a generally annular housing having a central axis and an internal channel extending along the central axis terminating at a priming end of the housing and at an opposed lancing end of the housing;
(2) a priming knob rotatably and translationally connected about the housing to permit rotation about an axis of rotation generally parallel to the central axis of the housing and translation in a direction parallel to the axis of rotation, wherein the priming knob comprises a slanted priming notch for priming interaction with a priming protrusion of a lancet carrier, (3) a lancet carrier translationally mounted within the internal channel of the housing for carrying a lancet along a strike path that is generally parallel with the central axis, the strike path of the lancet carrier starting from a primed position toward the priming end of the housing wherein the lancet is shielded by the housing and ending at a lanced position wherein a tissue penetrating portion of the lancet extends outwardly from the lancing end of the housing, the lancet carrier comprising the priming protrusion for priming interaction with the slanted priming notch of the priming knob; and
(4) a lancet carrier driver disposed within the internal channel of the housing, the lancet carrier driver being operatively engaged with the lancet carrier when driving the lancet carrier along the strike path from the primed position to the lanced position;
wherein when the slanted priming notch is in priming interaction with the priming protrusion of the lancet carrier;
(i) rotation of the priming knob;
(ii) movement of the priming knob along an axis generally parallel to the central axis of the housing;
or (iii) both rotation of the priming knob and movement of the priming knob along an axis of generally parallel to the central axis of the housing, primes the lancet driver and places the lancet carrier into the primed position.

Abstract
A lancing device is used with a lancet for lancing body tissue to result in a wound for bleeding. An improved lancing device has a priming knob having a slanted priming notch rotatably connected to the lancing device about an axis of rotation generally parallel to a central axis of the lancing device and a strike path of a lancet carrier. Rotation, translation, or both rotation and translation of the priming knob allows a user to prime the lancing device.

7. A method for priming a lancing device, wherein the method comprises the steps of, by a user:
-
(i) inserting a lancet into a lancet carrier of a lancing device comprising the improvement of;
a priming knob, comprising a slanted priming notch, rotatably connected to the lancing device about an axis of rotation generally parallel to a central axis of the device, wherein (i) rotation of the priming knob;
(ii) movement of the priming knob along an axis generally parallel to the central axis of the device;
or (iii) both rotation of the priming knob and movement of the priming knob along the axis generally parallel to the central axis of the device, primes a lancet driver and places the lancet carrier into a primed position,(ii) priming the lancing device by;
rotating the priming knob of the lancing device;
moving the priming knob along an axis generally parallel to the central axis of the housing;
or both rotating the priming knob of the lancing device and moving the priming knob along an axis generally parallel to the central axis of the housing,(iii) placing the lancing end of the device next to the user'"'"'s body tissue, and (iv) lancing the user'"'"'s body tissue. - View Dependent Claims (8, 9)

10. In a lancing device, for use with a lancet carried by a lancet carrier, for lancing body tissue to result in a wound for bleeding, the improvement comprising:
a priming knob, comprising a slanted priming notch, rotatably connected to the lancing device about an axis of rotation generally parallel to a central axis of the device, wherein (i) rotation of the priming knob;
(ii) movement of the priming knob along an axis generally parallel to the central axis of the device;
or (iii) both rotation of the priming knob and movement of the priming knob along the axis generally parallel to the central axis of the device, primes a lancet driver and places the lancet carrier into the primed position, thereby priming the device.- View Dependent Claims (11)
