摘要：
The present invention provides for a biocompatible drug delivery device for the targeted treatment of cancer that is implantable within the tumorous mass of a patient. In one embodiment, the device comprises two polarizable elements mechanically coupled by a connecting element. The device also comprises one or more cancer treatment agents. When the polarizable elements are depolarized, such as by the application of ionizing radiation, the two polarizable elements are repelled from each other and release the cancer treatment agent. In another embodiment, one or more treatment agents are expelled from a miniaturized syringe when internal pressure of the device is increased by the production of gas bubbles in response to the application of ionizing radiation.
