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.

125. 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 carried in the delivery fluid in response to an acoustic control signal, the effective concentration being the concentration of the first active form in the delivery fluid;
wherein the second form is an inactive form of the primary material. - View Dependent Claims (126, 127, 128, 129, 130, 131, 132)

133. 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 shape-changing structure capable of changing in at least one dimension in response to an acoustic control signal, the change in at least one dimension of the shape-changing structure modifying the distribution of the primary material between a first active form carried in the delivery fluid and a second form, and the effective concentration being the concentration of the first active form in the delivery fluid. - View Dependent Claims (134, 135, 136, 137, 138, 139, 140)

141. 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;
a pump configured for pumping delivery fluid from the delivery reservoir to a downstream location via the outlet; 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. - View Dependent Claims (142, 143, 144, 145, 146, 147, 148, 149, 150, 151, 152, 153, 154)
