More Information
Summary:An apparatus and method 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 and method for treating a tumor or cancerous area occurring around a conduit or duct in the body. The apparatus includes a catheter provided with a ribbed balloon encircling a portion near its distal end. When inserted into the body over a guide wire and transported to the site of the stenosis, the balloon is inflated one or more times and, due to the ribbed balloon, blood perfuses around the catheter during the treatment. A radioactive source of material is inserted through the catheter to the site of the stenosis or cancer where it is maintained in position for a period of time to reduce the occurrence of re-stenosis or cancer. A guide wire provided with a removable core can be utilized to properly maneuver the catheter to the site of the stenosis or cancer.
