A lancet driver is provided wherein the driver exerts a driving force on a lancet during a lancing cycle and is used on a tissue site. The driver comprises of a drive force generator for advancing the lancet and a processor coupled to the drive force generator capable of changing the direction and magnitude of force exerted on the lancet during the lancing cycle. The driver further includes a human interface on the housing providing at least one output for communicating with the patient.

A method is provided for controlling a lancet velocity profile. A velocity of a moving lancet is measured at a known position. The measured velocity of the lancet is compared with an appropriate velocity for the lancet at the known position. A force is applied to the lancet to adjust the velocity of the lancet.

An agent injection device is provided that is capable of injecting an agent to a known predetermined tissue depth. An injection member has an elongate injection shaft with an outlet port configured to dispense an agent at a controllable time. A controllable driver is coupled to the elongate injection shaft and is configured to drive the injection member into target tissue. A velocity control system is in communication with the controllable driver and is configured to control the velocity of the elongate injection shaft.

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.
