Infusion catheter and balloon catheter system and method

Abstract

Systems and methods for treatment of vascular lesions. The system includes a drug-eluting distal portion of a drug-eluting catheter and a balloon of a balloon catheter configured for positioning with a vascular lesion. The method entails securing the drug-eluting distal portion to the inner wall of a blood vessel with the balloon, and delivery of therapeutic agents into the blood vessel wall while the drug-eluting distal portion is held against the wall of the blood vessel by the balloon. The distal infusion portion of the drug infusion catheter is first located within the lesion. After the drug infusion portion is in position, the balloon of the balloon catheter is translated into the lesion and inflated to press the drug-eluting portion into contact with the blood vessel wall and a therapeutic agent is delivered through the drug-eluting portion.
