Abstract

In one aspect, a body fluid sampling device is provided using a penetrating member to extract fluid from an anatomical feature. The device comprises a penetrating member actuator for moving the penetrating member inbound towards the anatomical feature and a non-spring based, penetrating member retractor for moving the penetrating member outbound away from the anatomical feature. The penetrating member actuator may be adapted to move the penetrating member at a velocity greater than a velocity achieved by the penetrating member retractor.
