Abstract
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.
Claims14
A method for charging or re-charging an implanted device with a bioactive material comprising:
- a. introducing a charge into the implanted device;
- b. introducing a bioactive material in ionic form or in a neutral complex that will dissociate tonically in the presence of the charge on the implanted device.
An implantable device which is capable of being charged or re-charged without removal from the body in which it is implanted comprising a device made of material which can be induced to form a charge and to retain the charge sufficiently long to act electrostatically and attract a charged substance to itself.
