An elongated catheter assembly for the intravascular delivery of therapeutic fluids which has an infusion section on the distal end for the discharge of fluids to the exterior of the catheter and an elongated sheath which moves longitudinally to vary the length of the infusion section through which treatment fluid can pass. The sheath preferably is elongated so that the position thereof can be adjusted from the proximal end of the catheter assembly. In this manner, the effective length of the infusion section can be adjusted to the length of the treatment site, such as a thrombus.

An extendable guidewire system for introducing a dilatation catheter into the cardiovascular system. The guidewire has guidewire and extension sections with a connection therebetween 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 cardiovascular system, and the other section can be employed to extend the wire to change catheters.
