APPARATUS AND METHOD TO REDUCE RESTENOSIS AFTER ARTERIAL INTERVENTION

摘要

This invention is an apparatus guided by a guide wire (9) within a patient's artery for reducing restenosis after arterial intervention in the patient's artery. A radiation dose delivery wire (8) with a radiation source (8d, 8e, 8f) encapsulated within its distal end is inserted into a blind lumen (7) in a balloon catheter (5) to deliver radiation to a target area of the patient's artery.
