ABSTRACT:
An apparatus for treating an occlusion or constriction, such as a stenosis in a blood vessel or other conduit in the body, as well as an apparatus for treating bodily diseases (e.g. a tumor or cancerous area) occurring around a conduit or duct in the body. The apparatus includes a catheter which is correctly positioned within a conduit of the body utilizing a guide wire. The guide wire would pass through the entire length of the catheter, or a portion of the length of the catheter, and would exit the catheter through a constriction plug affixed to the end of the catheter. A radioactive treatment source wire is then introduced into the catheter and is maneuvered to the site of treatment. The constriction plug is provided with an internal diameter which is less than the diameter of the radioactive source wire, but greater than the diameter of the guide wire. This construction would prevent the radioactive source wire from remaining in the body after the catheter has been removed.
