A fine needle aspiration device with a modified handle and cannula through which a vacuum is delivered to the targeted tissue for removal of liquid or cellular samples is provided, the vacuum being provided via a flexible tubing capable of fitting within a restricted space such as, for example, a CT gantry. The system uses Low Frequency for data communications so it can achieve both low cost and long battery life. The at least one conductive via structure and the at interconnect-level metal line may provide a low resistance electrical path from the induced charge layer in a bottom semiconductor layer to electrical ground, discharging the electrical charge in the induced charge layer. The connection includes a support element fixedly arranged on the support and a connecting element that partially pivots the support element.
