Abstract
A needle system includes a needle arrangement having a hollow needle with a distal end opening, and a proximal end connected to an actuator body of an actuator device, and open to a cavity in the actuator body that has a changeable volume. The needle arrangement includes a rod with a distal tip and a shaft portion fits inside the needle. The cavity has an opening configured to interface with a fluid transportation device for allowing fluid into and/or out of the cavity for injecting and/or aspirating fluid through the needle. The rod tip is configured to seal the needle opening, and to unseal the needle opening when the rod is shifted distally relative to the needle. The rod interacts with the actuator device such that a change in volume of the cavity forces the rod in a distal direction to unseal the needle opening.
