Abstract
A drug delivery system can include a cylindrical structure extending in a longitudinal direction and formed from a substrate of an electrically conductive material. The cylindrical structure can include multiple electrodes extending laterally on the substrate at respective longitudinal locations. The electrodes each have an electrical resistance small enough to conduct current laterally along the substrate without heating the cylindrical structure. The cylindrical structure can include at least one substrate portion extending longitudinally between a respective pair of electrodes. Each substrate portion can have an electrical resistance high enough to conduct current longitudinally between the electrodes and resistively heat the respective substrate portion in response to the current conducted therethrough. A dose of a drug can be disposed on each substrate portion and configured to volatilize into a gas in response to the resistive heating of the respective substrate portion.
