Abstract
A system for delivering an agent to tissue surrounding a target vessel includes an elongate delivery device and a source coupled to a proximal tubular portion of the device. A first lumen extends through the tubular portion and an expandable sheath of the device, wherein the expandable sheath has a proximal end that surrounds and overlies a distal end of the tubular portion. The device further includes a stiffening member, attached to the sheath, and a balloon attached to the stiffening member, at a location spaced apart from the sheath. A second lumen extends, within the tubular portion and the stiffening member, to the balloon. A volume of fluid may be delivered, from the source, through the first lumen and into a section of the target vessel that is downstream from the expandable sheath and upstream of the balloon, in order to expand the sheath, fill the section and apply a pressure sufficient to cause extravasation of the section.
