ABSTRACT:
A catheter such as a medical catheter for PTCA procedures or the like. The catheter has a longitudinally extending wire therein, typically a steering wire. A catheter hub is positioned on the proximal end of the catheter. By this invention, the wire defines a coiled end positioned within a bore of the catheter hub and secured to the hub. Thus, fluids can flow through the bore of the hub and coiled wire end to and from the catheter, for example for the purpose of inflating or deflating a catheter balloon. At the same time, the same hub can be used to steer the distal end of the catheter by rotation of the hub in a conventional catheter steering technique.
