1. A system comprising:
- a signal-bearing medium bearing one or more instructions related to controlling an osmotic pump device, the one or more instructions including;
instructions for generating an electromagnetic control signal including frequency components absorbable by an electromagnetically responsive control element of a remotely controllable valve, the valve configured to adjust the movement of fluid into or out of the osmotic pump device; and
instructions for remotely transmitting the electromagnetic control signal to the osmotic pump device in an environment with signal characteristics sufficient to produce mechanical, thermal or chemical activation of the electromagnetically responsive control element in the remotely controllable valve of the osmotic pump device to control the pumping rate of the osmotic pump device.

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