ABSTRACT:
A method for inhibiting restenosis including local application of an oxidizing agent to blood vessel walls. Preferred oxidizing agents include peroxides, most preferably hydrogen peroxide. Oxidizing agents can be delivered utilizing drug delivery balloon catheters. Preferred delivery catheters include an inflatable balloon having a perfusion lumen therethrough to allow for longer application periods. Oxidizing agents can be delivered either alone or in conjunction with radiation or stent delivery. One method includes local delivery of 0.1% hydrogen peroxide to a dilated stenosis wall for a period of 10 minutes at a rate of 0.5 cc per minute.
