Abstract: 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 having at least one axial fold in a deflated condition, a tissue engaging member comprising at least one straight wire extending along at least part of the longitudinal axis of the expandable member, and a therapeutic agent disposed on at least the expandable member or the tissue engaging member. The at least one straight wire of the tissue engaging member is located inside the at least one fold of the expanded member when in the deflated condition. The tissue engaging member is configured for deployment at a select location upon inflation of the expandable member. A method of delivering a therapeutic agent is also provided.
