Abstract
The present invention concerns a novel drug delivery unit. The drug delivery unit comprises a medical material and a quantity of gel. Also provided is a permeable membrane. The permeable membrane surrounds the gel. In addition, the present invention also includes an electrical transmission mechanism. The electrical transmission mechanism is operably coupled to the gel to cause the gel to controllably change in shape in response to a voltage applied to the electrical transmission mechanism.
