Abstract

Methods and apparatus provide a therapeutic fluid to devices implanted in the body, for example to containers of devices implanted in the eye of a patient. The methods and apparatus may comprise an injector to increase an amount of therapeutic agent injected into the device implanted in the eye, or a structure to receive the therapeutic fluid within the device implanted in the eye, or combinations thereof. The device implanted in the eye may comprise a reservoir chamber having a fluid with a density different than the therapeutic fluid, and the apparatus can be adapted to at least partially separate the implanted device fluid from therapeutic fluid within the reservoir chamber to increase and amount of therapeutic fluid placed in the reservoir chamber.
