-
providing a lancer with an alternate site tip having a plurality of crenellations extending in a distal direction;
positioning the lancer over an intended lancet puncture site such that the crenellations on the alternate site tip exert force on skin surrounding the lancet puncture site;
activating the lancer to drive the lancet into the lancet puncture site; and
rotating the lancer to rotate the crenellations of the alternate site tip and thereby enhance blood flow from the lancet puncture site. - View Dependent Claims (11, 12, 13, 14, 15)
