A bidirectional long distance driver for Ethernet, named Ethernet Booster, is disclosed that comprises a forward transmission circuit and a backward transmission circuit, wherein each of the circuits includes Ethernet interface socket RJ45, an impedance matching circuit, power amplifying circuit and frequency compensation circuit. A transport arm supports the holding mechanism. A first actuator is operatively connected to the first catheter deflection assembly and operable upon movement to selectively effect displacement of the distal end. As a result, charge leakage between the floating gate and control gate is reduced.
