ABSTRACT:
The catheter is formed by a housing having a size and shape which fits readily into the hand of the user. An elongate tube is connected to and extends from the housing. The elongate tube is formed from a flexible polymeric material and constructed of three portions, a proximal portion, a medial portion, and a distal portion. Each of the portions is coaxial with one another and the longitudinal axis of the catheter housing. In addition, each of the portions has substantially the same outer circumference. The proximal and distal portions are formed of a flexible polymeric material which has a higher durometer of hardness than that of the medial portion. A pair of control wires extend longitudinally through the proximal, medial, and distal portions and parallel to the axis of the coaxial portions for selectively bending the portions in response to movement of the control wires. A control wheel is carried by the housing for controlling the movement of the control wires to thereby bend the selected portions and remotely manipulate the catheter within a human body. At least one lumen extends from the catheter body through each of the proximal, medial and distal portions of the elongate tube to form a working channel therein.
