Abstract
Devices, systems and methods for treating medical conditions using cell therapy via body lumens. Localized delivery is achieved with the use of a stent-like expandable body seeded with cells. The expandable body is expanded to contact at least a portion of the inner walls of the body lumen and the cells, cellular products and/or other therapeutic agents are delivered to the surrounding tissue. The therapeutic benefit provided is dependent on the type of cells used and the features of the expandable body.
