Injectable controlled release fluid delivery system

摘要

Embodiments of a material delivery device including a deformable reservoir and associated controllable output mechanism are described. Methods of use and control of the device are also disclosed. According to some embodiments, a material delivery device may be placed in an animal in order to controllably dispense at least one material into the animal. The material delivery device may include a programmable mechanism to control the release of the material into the animal. In selected embodiments, a remote controller may be used to program or to control the material delivery device. Some embodiments are described wherein a magnetic field, an electric field, or electromagnetic control signal may be used.

主权项

1. A material delivery kit, comprising:
at least one percutaneous injection mechanism including a syringe; at least one material delivery device enclosed in the syringe, the at least one material delivery device configured for percutaneous injection into an animal using the at least one injection mechanism, the at least one material delivery device including:
at least one collapsible reservoir having a biologically inert collapsible outer surface, the collapsible reservoir configured to receive, retain and controllably release at least one material from the at least one collapsible reservoir; andat least one controllable output mechanism coupled to the at least one collapsible reservoir and defining at least one outlet through which the at least one material may be released, the at least one controllable output mechanism including at least one control circuitry configured to activate the at least one controllable output mechanism and configured to control the release of the at least one material from the at least one collapsible reservoir and through the at least one outlet; andwherein the at least one controllable output mechanism includes at least one thermally-responsive gel or magnetically-responsive material.
