Abstract
The present invention provides a medical system for the administration of a pharmaceutical agent in vivo to a patient. The medical system includes a medical implant positionable in a body of a patient. A pharmaceutical agent in disposed on the medical implant and at least partially coated with a reactive coating. The reactive coating act to controls the release of the pharmaceutical agent. An energy unit is provided for transmitting an energy signal to the reactive coating, wherein the reactive coating reacts to the energy signal to increase the release rate of the pharmaceutical agent.

49. A method of releasing a pharmaceutical agent from an implantable device comprising the steps of:
-
providing an implantable device impregnated or coated with a pharmaceutical agent, the implantable device having a barrier substantially limiting release of the pharmaceutical agent therethrough;
implanting the implantable device in tissue in a body; and
directing energy at the implantable device, wherein the energy directed at the implantable device disrupts the barrier thereby allowing elution of the pharmaceutical agent through the barrier to the tissue. - View Dependent Claims (56)
