Abstract

A device for delivering a composition to a hollow body region is disclosed. In one aspect, the device comprises a first longitudinal member and a second longitudinal member. Both of the longitudinal members may comprise conductive electrodes. The longitudinal members are further configured to be connected to an energy source such that the conductive electrodes are configured to generate an energy field. At least one of the longitudinal members further comprises a delivery element configured to deliver at least one composition to the body region, such that the composition is delivered in a direction that is influenced by the generated energy field. In one aspect, the body region is a vessel comprising an occlusion.
