Abstract
The invention relates to minimally invasive device for delivering therapeutic or diagnostic agents into a vessel wall. The device includes an introducer tube, a tubular member having a proximal end, a distal end, and a first lumen extending therebetween, the tubular member being slidably disposed within the introducer tube; a plurality of hollow delivery struts, each delivery strut adapted to pierce through inner most layers of the vessel wall and each comprising at least one exit port and at least one stopper to prevent the delivery strut from piercing through the outer most layers of the vessel wall. The delivery struts are disposed on the distal end of the tubular member and are in fluid communication with the first lumen. The invention also relates to methods of delivering the device of this invention and methods of treating conditions or diseases of body lumens.
