Acoustically controlled substance delivery device
First Claim
1. A delivery device comprising:
- a delivery reservoir configured to contain a delivery fluid, the delivery reservoir having at least one outlet through which the delivery fluid may exit the delivery reservoir;
a delivery fluid contained within the delivery reservoir;
a primary material contained within the delivery reservoir and having a controllable effective concentration in the delivery fluid; and
at least one acoustically responsive control element adapted for modifying the distribution of the primary material between a first active form carried in the delivery fluid and a second form in response to an acoustic control signal, the effective concentration being the concentration of the first active form in the delivery fluid.

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, an acoustic control signal may be used.

82. A method of controlling a delivery device, comprising:
-
generating an acoustic control signal including frequency components absorbable by an acoustically responsive control element of a delivery device in an environment, the delivery device including a fluid-containing structure containing a delivery fluid and a quantity of primary material, the primary material being distributed between a first active form and a second form and having an effective concentration in the delivery fluid equal to the concentration of the first active form in the delivery fluid, wherein the effective concentration of the primary material in the delivery fluid is controllable by the acoustically responsive control element; and
remotely transmitting the acoustic control signal to the delivery device with signal characteristics sufficient to activate the acoustically responsive control element in the delivery device to control the effective concentration of primary material in the delivery fluid in the delivery device. - View Dependent Claims (83, 84, 97, 98, 102, 104, 109, 138, 139, 140, 141, 142, 143, 144)
