Abstract
Electromotive delivery of macromolecules can be provided using a delivery device including a first chamber for contacting a macromolecule delivery medium to a surface of a tissue or other anatomy of a patient; and a second chamber for contacting a receiving medium to the patient. A first electrode can be disposed in the first chamber so as to not directly contact the macromolecule delivery medium. A second medium having a buffering agent can be used to keep the first electrode from coming into direct contact with the macromolecule delivery medium. A second electrode can be disposed within the receiving medium in the second chamber such that the second electrode does not directly contact the patient. An electric field can be generated using the first and second electrodes in order to cause the macromolecule delivery medium to move into the tissue of interest from the first chamber of the delivery device.
