Abstract
An apparatus providing the benefits of a catheter with a fixed guidewire, while retaining the advantages of a catheter with an adjustable, removable, and exchangeable guidewire. The catheter may be designed for use in the urinary tract, cardiovascular system, or other body passages. The guidewire is advanced through the catheter from the proximal to the distal end for the required distance. This may be sufficient to make the catheter and the guidewire coextensive or to make either the catheter or guidewire protrude from the distal end, as desired. The guidewire may be secured to the proximal end of the catheter by rotation of a compressible fixation device. The connection is frictionally sealed. The guidewire may be rotated with respect to the catheter in the same manner as with a fixed wire catheter. Opposite rotation of the compressible fixation device frees the guidewire for removal, advancement or exchange.
