1. A steerable dilatation catheter means comprising:
- a flexible catheter comprising a spring coil body defining a lumen, each of said catheter and said spring coil body having proximal and distal ends, the distal end of said spring coil body being closed, and said spring coil body having a flexible covering thereon,dilatation balloon means positioned concentrically around the distal end of said spring coil body,a deflection wire having proximal and distal ends and being substantially co-extensive with said spring coil body, the distal end of said deflection wire being attached to the distal end of said spring coil body, andcontrol means attached to the proximal end of said catheter, the proximal end of said deflection wire extending to the control means, the control means having engaging means which fixedly engages the proximal end of said deflection wire to cause said deflection wire to be displaced distally or proximally, said displacement causing the distal end of said catheter to bend out of or toward the line of its longitudinal axis, and the control means having rotation means to cause said deflection wire and said catheter to rotate together to cause the distal end of said catheter to rotate about its longitudinal axis.

Abstract
This invention relates to steerable catheters. More particularly, this invention relates to steerable catheters comprising a flexible catheter comprising a spring coil body defining a lumen, the spring coil body having a flexible covering thereon; a deflection wire, the distal end of the deflection wire being attached to the distal end of the spring coil body; and control means attached to the proximal end of the catheter, the proximal end of the deflection wire extending through the control means and the control means having a torque means which fixedly engages said deflection wire.
