Remote controller for substance delivery system
First Claim
1. A method of delivering a fluid to an environment, comprising:
- generating a first electromagnetic control signal absorbable by an electromagnetically responsive control element to produce a change in effective concentration of a primary material in a delivery fluid in a delivery reservoir of a delivery device from a first effective concentration to a second effective concentration by modifying a distribution of primary material between a first active form and a second form within the delivery reservoir; and
generating a second electromagnetic control signal sufficient to cause delivery fluid containing primary material in solution at said second effective concentration to be released from the delivery reservoir into the environment.

Abstract
Embodiments of a system including a remotely controlled substance delivery device and associated controller are described. Methods of use and control of the device are also disclosed. According to some embodiments, a delivery device or related device may be placed in an environment in order to pump a material into the environment or into an additional fluid handling structure within the device. Exemplary environments include a body of an organism, a body of water, or an enclosed volume of a fluid. The concentration of a substance in the fluid to be delivered may be modified by a remote control signal. In selected embodiments, a magnetic field, an electric field, or electromagnetic control signal may be used.
