Abstract
An assembly is provided for seeking an area of interest within a body. The assembly includes an elongated directable member having a distal end for insertion into the body. The distal end includes a tip portion. The assembly also includes a deflector coupled to the directable member for deflecting the distal end of the directable member to direct the directable member within the body. The assembly further includes a sensor located in close proximity to the top portion of the directable member for sensing an area of interest within the body. The sensor generates an indicator signal upon detection of the area of interest. The assembly still further includes a control unit coupled to the deflector for controlling deflection of the distal end of the directable member by the deflector. The control unit generates a control signal to drive the deflector. The control unit stops deflection of the distal end of the directable member in response to the indicator signal generated by the sensor upon detection of the area of interest. The control unit holds the tip portion of the directable member in a stationary position directed toward the area of interest.
