| 摘要 |
An implanted device such as a stent is provided which is capable of holding an induced charge or sufficient magnitude that the device may, by electrostatic means, attract the bioactive material to itself. The charge, either positive or negative, or relative to the bioactive material sufficiently positive or negative, is deposited into the implantable device via an exterior induction coil. The implantable device itself becomes an introduced "dosage form", becoming part of a biologically closed electric circuit, through which the bioactive material is attracted to the implanted device.
