Abstract
An apparatus for delivering at least one therapeutic agent to an ocular tissue of a subject includes at least one electrode, a medicament layer including the at least one therapeutic agent, an electrical signal source, and logic configured to control the electrical signal source. The at least one electrode has oppositely disposed, dome-shaped first and second major surfaces. The first major surface is curved such that the first major surface substantially conforms to a contour of the ocular tissue when placed in contact with the ocular tissue. The medicament layer is disposed on at least a portion of the second major surface. The electrical signal source provides a signal having certain characteristics and is electrically connected to the at least one electrode. The certain characteristics comprise at least one orienting frequency and at least one motivating frequency sufficient to motivate the at least one therapeutic agent into the ocular tissue.
