Abstract:
1. A method of lancing the tissue of a patient comprising: (a) providing an electromagnetic driver having a tissue penetration element having a tip configured to penetrate tissue and a shaft portion; (b) disposing the tissue penetration element in proximity to the tissue of the patient; (c) driving the tissue penetration element distally towards the tissue of the patient; (d) determining contact between the tip and the tissue of the patient; (e) advancing the tip into the tissue during a penetration stroke to a position of maximum inward displacement that is determined electronically via a position sensor; (f) monitoring motion of the tissue penetration element and allowing the tissue penetration element to settle upon reaching the point of maximum inward penetration for at least about 1 millisecond with no driving force imposed on the tissue penetration element until any motion of the tissue penetration element has stopped; and (g) displacing the tissue penetration element proximally over a withdrawal stroke and removing the tip from the tissue, the allowing the tissue penetration element to settle upon reaching the point of maximum inward penetration for at least about 1 millisecond and displacing the tissue penetration element creating a spontaneous flow of a blood sample without milking.
