Abstract
A minimally intrusive catheter having a deflectable tip. A remotely bendable section adjacent a distal tip enables movement of the tip between a neutral position and angularly disposed positions. A deflection control lever on a proximal control member causes deflection of the distal tip by means of two sets of operating cables which are operatively connected at one end to the control member and at the other end to axially spaced locations along the controllably bendable section. The control member includes a mechanism for sequentially displacing cables within each set. The operating cables are constructed of flat ribbons to increase their flexibility in the bending plane while still providing axial strength. The wires are closely encased in an oval-shaped sheath along the length of the catheter.
