1. A lancing device, for use with a lancet for lancing body tissue to result in a wound for bleeding, the lancing device comprising:
- (a) a housing having an internal channel extending within the housing from a first lancing end toward a second end of the housing;
(b) a lancet carrier translationally mounted within the internal channel for carrying a lancet along a strike path of the lancet carrier, said strike path starting at a primed position toward the second end of the housing and extending to a lanced position at the first lancing end of the housing,(c) a lancet driver for storing energy and then driving the lancet carrier along the strike path from the primed position to the lanced position; and
(d) a first cantilevered priming arm comprising a first arm portion that is generally parallel to the internal channel and a second arm portion that is generally perpendicular to the internal channel, wherein the second arm portion is connected to the lancet carrier,wherein movement of the first arm portion toward the internal channel draws the lancet carrier to a primed position and stores energy in the lancet driver.

Abstract
A lancing device is used with a lancet for lancing body tissue to result in a wound for bleeding. The lancing device has a cantilevered priming arm having a first arm portion that is generally parallel to an internal channel of the device and a second arm portion that is generally perpendicular to the internal channel. The second arm portion is connected to a lancet carrier and movement of the first arm portion toward the internal channel draws the lancet carrier to a primed position and stores energy in a lancet driver.

13. A lancing device, for use with a lancet for lancing body tissue to result in a wound for bleeding, the lancing device comprising:
-
(a) a housing having an internal channel extending within the housing from a first lancing end toward a second end of the housing; (b) a lancet carrier translationally mounted within the internal channel for carrying a lancet along a strike path of the lancet carrier, said strike path starting at a primed position toward the second end of the housing and extending to a lanced position at the first lancing end of the housing, (c) a lancet driver for storing energy and then driving the lancet carrier along the strike path from the primed position to the lanced position; and (d) a first cantilevered priming arm comprising a first arm portion that is generally parallel to the internal channel and a second arm portion that is generally perpendicular to the internal channel, wherein the second arm portion is connected to the lancet carrier, (e) a second cantilevered priming arm comprising a first arm portion that is generally parallel to the internal channel and a second arm portion that is generally perpendicular to the internal channel, wherein said first and second cantilevered priming arms are disposed on opposing sides of the internal channel, wherein movement of the first arm portion of the either or both of the first or second cantilevered arms toward the internal channel draws the lancet carrier to a primed position and stores energy in the lancet driver, and (e) a pair of firing ramps disposed within the internal channel at a position wherein the firing ramps and the second portions of the priming arms respectively interact as the lancet carrier is drawn to a primed position, said respective interaction to disengage the connection between the second portion of the respective priming arm and the lancet carrier when the lancet carrier has reached the primed position thereby releasing energy stored in the lancet driver and firing the device. - View Dependent Claims (14)

16. In a lancing device having a housing, an internal channel extending within the housing, a lancet carrier disposed in the internal channel, and a lancet driver, wherein a user applies force to a housing to prime that lancet carrier into a primed position, the improvement comprising:
-
a cantilevered priming arm comprising a first arm portion that is generally parallel to the internal channel and a second arm portion that is generally perpendicular to the internal channel, wherein the second arm portion is connected to the lancet carrier, wherein movement of the first arm portion toward the internal channel draws the lancet carrier to a primed position and stores energy in the lancet driver. - View Dependent Claims (17)
