ABSTRACT:
The catheter has a housing of such a size as to be readily held in the hand of the user, and a tubular proximal portion connected to and extending from the housing. The proximal portion is formed of a flexible polymeric material. The distal portion is coaxial with and is adjacent to the proximal portion. The distal portion is also formed of a flexible polymeric material and it has substantially the same outer circumference as the proximal portion. The distal portion is more flexible than the medial portion. A pair of control wires extend longitudinally through the proximal and distal portions and parallel to the axis of the coaxial portions for bending the flexible portions in response to movement of the control wires. A control is carried by the housing for controlling the movement of the control wires to thereby bend the flexible portions and remotely manipulate the catheter within a human body.
