The United States Patent Office (USPTO) has published a notice to the effect that the USPTO's computer programs require that patent applicants reference both a serial number and indicate whether an application is a continuation or continuation-in-part. Stephen G. Kunin, Benefit of Prior-Filed Application, USPTO Official Gazette Mar. 18, 2003, available at http://www.uspto.gov/web/offices/com/sol/og/2003/week11/patbene.htm. The present applicant entity has provided above a specific reference to the application(s) from which priority is being claimed as recited by statute. Applicant entity understands that the statute is unambiguous in its specific reference language and does not require either a serial number or any characterization, such as “continuation” or “continuation-in-part,” for claiming priority to U.S. patent applications. Notwithstanding the foregoing, applicant entity understands that the USPTO's computer programs have certain data entry requirements, and hence applicant entity is designating the present application as a continuation-in-part of its parent applications as set forth above, but expressly points out that such designations are not to be construed in any way as any type of commentary and/or admission as to whether or not the present application contains any new matter in addition to the matter of its parent application(s).

All subject matter of the Related Applications and of any and all parent, grandparent, great-grandparent, etc. applications of the Related Applications is incorporated herein by reference to the extent such subject matter is not inconsistent herewith.

BACKGROUND

- Top of Page


Implantable controlled release devices for drug delivery have been developed. Certain devices rely upon the gradual release of a drug from a polymeric carrier over time, due to degradation of the carrier. Polymer-based drug release devices are being developed that include a drug in a ferropolymer that may be heated by an externally applied magnetic field, thus influencing the drug release. MEMS based drug release devices that include integrated electrical circuitry are also under development, as are MEMS based systems for performing chemical reactions. Implantable delivery devices have been developed for drug delivery purposes. Wireless transmission of electromagnetic signals of various frequencies is well known in the areas of communications and data transmission, as well as in selected biomedical applications.

SUMMARY

- Top of Page


The present application relates, in general, to the field of fluid delivery devices, systems, and methods. In particular, the present application relates to remotely controlled delivery devices in which the concentration of a material in a fluid to be delivered may be varied. Control signals may be carried between a remote controller and a delivery device in an environment by electrical, magnetic, or electromagnetic fields or radiation. Embodiments of a system including a remotely controlled delivery device and associated controller are described. Methods of use and control of the device are also disclosed. According to various embodiments, a delivery device may be placed in an environment in order to eject or release a material into the environment. Exemplary environments include a body of an organism, a body of water or other fluid, or an enclosed volume of a fluid. According to some embodiments, a delivery device may provide for delivery of a fluid into a downstream fluid-handling structure. The foregoing summary is illustrative only and is not intended to be in any way limiting. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features will become apparent by reference to the drawings and the following detailed description.
