Abstract
An intravascular medical device including an elongate shaft and a variable-length ionizing radiation source disposed on the distal end thereof. The present invention may be manifested as a source wire, a guide wire, a catheter or other suitable intravascular device with an adjustable length radiation source. For example, the adjustable source may be implemented on a wire having a variable-length radioactive tip, on a balloon catheter having a variable-length balloon inflated with a radioactive fluid, or on a catheter having means for advancing and retracting radioactive seeds of variable number and/or spacing.
