摘要：
Method of delivering a therapeutic agent includes delivering at least a portion of a medical device within a vasculature. The medical device includes a tubular member having a proximal end and distal end defining a longitudinal axis therebetween, an expandable member proximate the distal end of the tubular member, a tissue engaging member proximate the expandable member, a sheath disposed over the tissue engaging member, and a therapeutic agent disposed on at least the expandable member or the tissue engaging member. The method further includes deploying the tissue engaging member at a select location by displacement of the sheath relative the tissue engaging member, inflating the expandable member to engage the therapeutic agent with a vessel wall, deflating the expandable member, and withdrawing the medical device from the vasculature.
