Abstract
A catheter with an integral steerable guidewire converts linear movement of the guidewire to rotational movement at the distal end of the guidewire. The catheter has a guidewire lumen to receive the guidewire. The catheter and guidewire are constructed so that the guidewire can be reciprocated and rotated with respect to the catheter. The guidewire and catheter cooperate in a manner so that when the guidewire is reciprocated axially with respect to the catheter, that axial movement of the guidewire is converted into rotational movement.
