1. An implantable medical pump, comprising:
- a fluid reservoir;
a passive regulator assembly adjustable to a plurality of flow rate settings for regulating the flow of fluid from the fluid reservoir;
electromechanical control means for changing the passive regulator assembly from a first flow rate setting to a second flow rate setting when the electromechanical control means receives an induced voltage and in response to control signals; and
means for receiving radio frequency signals operative to maintain the induced voltage in the electromechanical control means in response to received radio frequency signals.

Abstract
In accordance with the present invention, an implantable pump is programmed non-invasively by means of a programmer that communicates flow rate information by means of radio frequency telemetry or other methods of non-invasive telemetry. The programmer also supplies power to the implantable pump during programming. The implanted rate-adjustable pump that receives rate information and power by telemetry preferably does not include a battery or any other type of internal power supply, relying only on the energy obtained from the programmer through telemetry.
