Patent Images
1. A lancing system configured to drive a lancet during a lancing cycle and used on a tissue site, the system comprising:
- a controllable electronic lancet driver coupled to the lancet;
a position sensor coupled to the controllable electronic lancet driver, the position sensor configured to detect position and velocity of the lancet in the tissue site; and
a processor coupled to said controllable electronic lancet driver, said processor configured to adjust velocity of the lancet to advance the lancet at a first desired velocity in a first layer of tissue, at a second desired velocity in a second layer of tissue, and at a third desired velocity in a third layer of tissue based on feedback of the position and velocity of the lancet from the position sensor.

Abstract
A method of penetrating tissue is provided. The method uses a lancet driver to advance a lancet into the tissue; advancing the lancet at a first desired velocity in a first layer of tissue; advancing the lancet at a second desired velocity in a second layer of tissue; and advancing the lancet at a third desired velocity in a third layer of tissue. In one embodiment, the method may including using a processor having logic for controlling velocity of the lancet in each layer of tissue.
