Energy facilitated composition delivery

摘要

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.

1. A method for delivering a composition to a body region, comprising:
advancing a first longitudinal member coupled to an energy source and comprising a first conductive electrode into the body region; advancing a second longitudinal member coupled to the energy source and non-overlapping with the first longitudinal member into the body region, the second longitudinal member comprising a second conductive electrode, wherein the first longitudinal member or the second longitudinal member comprises a delivery element configured to deliver at least one composition to the body region; generating an energy field using the first conductive electrode and the second conductive electrode; and delivering the composition to the body region after generating the energy field such that migration of the composition in the body region is in a direction influenced by the generated energy field.
