ABSTRACT:
A vascular catheter has a highly flexible distal section. A biplanar control system is provided for enabling and controlling the movement of the distal catheter section and tip in any direction in a manner such that the distal tip is capable of accessing any point on the wall of the chamber entered. Dual-wire biplanar control system embodiments include a vertical deflection control wire operable to deflect the distal tip of the catheter in a controlled manner in a vertical plane substantially parallel to the longitudinal axis of the tubular catheter and a lateral deflection control wire operable to deflect the distal tip of the catheter in a controlled manner in a lateral plane substantially perpendicular to the longitudinal axis of the tubular catheter. A one-wire system for both vertical and lateral control is also described.
