1. A method of treating an aneurysm in a vessel of a patients vasculature comprising the steps of:
providing a coil delivery system comprising a microcatheter and a coil, wherein the microcatheter comprises a proximal end portion and a distal end portion, and wherein the coil is at least partially coated with a photon-activatable gel material;
positioning the coil delivery system within the vessel so that the distal end portion of the microcatheter is disposed at a neck of the aneurysm;
deploying the coil into a cavity of the aneurysm; and
activating the photon-activatable gel material using an x-ray photon source external to a patient's body, wherein activation of the photon-activatable gel material leads to physical enlargement of the coil within the cavity of the aneurysm thereby isolating the aneurysm from the vessel.
