摘要

Apparatus for delivering a drug to a target site of a body comprising: a dispersing member adapted to vibrate when acoustically excited; a source of acoustic energy controllable to couple acoustic energy to the dispersing member to excite it to vibrate; and a drug adhered to the dispersing member so that when the acoustic source excites the dispersing member, the drug is dispersed therefrom.
