Abstract

A device for penetrating tissue for fluid collection and delivery is provided having a driving actuator interconnected to and driving axiai reciprocating motion of a penetrating member. A hollow member attached between the penetrating member and a reservoir permits axia! reciprocation of the penetrating member while isolating the vibrations from the reservoir. A handpiece allows for one- handed use of the device, A slider device attached to the reservoir permits one- handed delivery and extraction of materials from the reservoir.
