Abstract: An implant insertion device includes a vibrational actuator generating axial vibrations, a coupler interconnected to the actuator and selectively retaining an implant with penetrating electrodes. The coupler has a distal end cavity at one end dimensioned to receive and retain at least a portion of the implant. Vibrations are transferred to the electrodes during insertion. A vacuum assembly connects to the coupler and provides a negative pressure, or suction force, when a vacuum source is attached and activated. This suction force is sufficient to hold the implant to the distal end of the coupler. Deactivation of the vacuum source removes the suction force, causing the implant to detach from the coupler without perturbation of position. The insertion device may then be removed. A system to coordinate the operation of the actuator and movement of the device and/or tissue relative to one another for delivery of the implant is also provided.

Abstract: A lancing device with an ejector that is movably retained with a housing in proximity to a lancet and is selectively movable between a home position, a first eject position, an intermediate position defined by contact of the ejector with the lancet, and a second eject position. The ejector is rotatable to move from the home to first eject position and is linearly translatable to move between the first and second eject positions. The ejector includes an arm that extends within the housing and engages the lancet, an exterior portion that is actuated by a user, and a post extending therebetween. The post extends through a slot in the housing which limits the linear movement and direction of the ejector. Upon rotation of the ejector, the arm extends through an opening at the rear of the carriage holding the lancet to permit access to the lancet.

Abstract: A device for penetrating tissue for fluid collection and delivery is provided having a driving actuator interconnected to and driving axial reciprocating motion of a penetrating member. A hollow member attached between the penetrating member and a reservoir permits axial 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.
