Method of actuating implanted medical device

摘要

Methods are provided for medical treatment or diagnosis of a patient. The method includes implanting into the patient a device which comprises (i) a substrate in which at least one reservoir is located and covered by a first reservoir cap, (ii) a drug or sensor located in the reservoir, and (iii) control circuitry and a power source for disintegrating or permeabilizing the reservoir cap, and (iv) an external interface to receive incident light energy; and directing focused light to the external interface of the implanted device to actuate disintegration or permeabilization of the reservoir cap to release the drug or expose the sensor. The device may implanted onto or into the sclera or other tissue surface of the eye of the patient. The focused light may be laser light, which may be used to transmit power or data to the device.
