Abstract
An extendable guidewire for introducing a dilatation catheter into the cardiovascular system. The guidewire has main and auxiliary sections with a connector which permits the two sections to be joined together and separated simply by pushing the two sections together and pulling them apart. One of the sections can be used for positioning the catheter within the cardiovasuclar system, and the other section can be employed to extend the wire to change catheters.
