A therapeutic agent delivery device and method for eluting a therapeutic agent to a target location are disclosed. The device may comprise a first conductive element, a second conductive element, an electrochemical composition including an electrolyte and a therapeutic agent, and a permeable membrane covering the electrochemical composition. The first conductive element and the second conductive element are adapted to be connected to a voltage source. When the voltage source is connected to the first conductive element and the second conductive element, an electrochemical reaction occurs causing the therapeutic agent to pass through the permeable membrane and thereby to elute to a target location.
