Abstract
Apparatus, systems, and methods are provided for delivering stem cells or other agents to cardiac tissue surrounding a cardiac vessel or to tissue adjacent other body lumens. The apparatus includes an expandable member and a source of one or more agents communicating with a lumen extending between proximal and distal ends of the apparatus. The distal end of the apparatus is advanced through one or more body lumens until the distal end is disposed within or adjacent the target body lumen. The target body lumen is sealed, e.g., by expanding the expandable member, thereby isolating the target body lumen. One or more agents are delivered into the target body lumen with sufficient pressure to extravasate the one or more agents into tissue surrounding the target body lumen.
