NOVELTY - The electro-active prosthetic device (40) for attachment of implant to a tissue/organ e.g. eyelid to provide motion of the tissue/organ, comprises an electro-active polymer actuator (41), a cord implant (44) attached to the actuator, a source (45) of electrical voltage in controllable electrical contact with the actuator, where the biocompatible cord is configured for attachment to tissues of a living animal and for moving the tissue on application of the voltage to the actuator, and a sensor (46) to energize the actuator. The voltage source is a battery, a fuel cell or an induction coil.    USE - The electro-active prosthetic device is useful for attachment of the implant to a tissue/organ to provide motion of the tissue/organ, which includes an eyelid, facial skin, a facial muscle, an eyebrow, a bone, a diaphragm, a finger or a hand (all claimed).    ADVANTAGE - The electro-active prosthetic device provides improved function such as biocompatibility, electrical isolation, ion-impermeability, power access, secure mounting points and attachment points for attachment of the implant to the tissue thus allowing simple and controllable movement of the tissue to the patient.    DETAILED DESCRIPTION - The electro-active prosthetic device (40) for attachment of implant to a tissue/organ e.g. eyelid to provide motion of the tissue/organ, comprises an electro-active polymer actuator (41), a cord implant (44) attached to the actuator, a source (45) of electrical voltage in controllable electrical contact with the actuator, where the biocompatible cord is configured for attachment to tissues of a living animal and for moving the tissue on application of the voltage to the actuator, and a sensor (46) to energize the actuator. The voltage source is a battery, a fuel cell or an induction coil. When the implant is attached to the tissues, the activator is not in direct contact with the tissues. The sensor is an optical sensor, an optical blink sensor, a myoelectric sensor or a position sensor. The actuator comprises a water-proof outer cover. The implant comprises a sling, a cord, a membrane, a pulley or a lever. The biocompatible implant comprises a material consisting of a ligament, a connective tissue and a suture. An INDEPENDENT CLAIM is included for a method of using an electro-active prosthetic device.
