Abstract
Apparatus for delivering medicament media into tissue comprises a medicament supply assembly and an oscillatory drive assembly. The medicament supply assembly includes a medicament transfer surface, and the oscillatory drive assembly includes a housing, a coil mounted within the housing, and a magnet suspended within the housing. By applying an electrical drive signal to the coil, the housing can be oscillated to phonophoretically enhance delivery of medicament from the medicament transfer surface into tissue.
