1. A method of lancing the tissue of a patient comprising:
- (a) providing a tissue penetration element having a tip configured to penetrate tissue;
(b) disposing the tissue penetration element in proximity to the tissue of the patient;
(c) initiating a lancing cycle including advancing the tip into the tissue during a penetration stroke and displacing the tissue penetration element proximally over a withdrawal stroke; and
(d) acquiring tissue data based on an interaction between the tissue penetration element and the tissue during at least a portion of the lancing cycle.

Abstract
A method of lancing the tissue of a patient provides a tissue penetration element with a tip configured to penetrate tissue. The tissue penetration element is disposed in proximity to the tissue of the patient. A lancing cycle is initiated. The lancing cycle advances the tip into the tissue during a penetration stroke and displaces the tissue penetration element proximally over a withdrawal stroke. Tissue data is acquired based on an interaction between the tissue penetration element and the tissue during at least a portion of the lancing cycle.

5. A method of measuring tissue elasticity comprising:
-
(a) providing a lancing device comprising a lancet driver having a position sensor and a processor that can determine the relative position and velocity of a lancet based on measuring relative position of the lancet with respect to time;
(b) driving the lancet into tissue with the lancet driver to a position of maximum penetration and removing substantially all force imparted from the lancet driver to the lancet; and
(c) measuring an elastic recoil displacement of lancet in a proximal direction due to elastic recoil of target tissue. - View Dependent Claims (6)
