ABSTRACT:
An improved and simplified catheter construction is provided to enhance the steerability of the catheter. The catheter(s) includes an elongate flexible relatively torsionally rigid core wire attached securely at each of the proximal and distal ends of the catheter. The core wire adds sufficient torsional rigidity to the catheter to enhance the steerability of the catheter when the catheter is manipulated from its proximal end by the physician. The catheter avoids the need for incorporating helically braided tubes in the wall of the catheter. The invention may be used to make a catheter having a reduced outer diameter or an increased inner luminal diameter.
