    摘要： The present disclosure provides robust implantable micro-component electrodes that can be used in a variety of medical devices. The medical device may be a neural probe that can monitor or stimulate neural activity in an organism's brain, spine, nerves, or organs, for example. The micro-component electrode has a small physical profile, with ultra-thin dimensions, while having high strength and flexibility. The micro-electrode has an electrically conductive core material, e.g., carbon. The surface of the core material includes one or more electrically conductive regions coated with an electrically conductive material and one or more non-conductive regions having an electrically non-conductive biocompatible polymeric coating. Implantable devices having such micro-components are capable of implantation in an organism for very long durations.

    摘要： A neural drug delivery system with fluidic threads implantable into tissue, including: a plurality of fluid delivery conduits configured to transport fluid and having an array of fluid delivery ports through which the fluid is selectively released; a plurality of port gates each including a mesh structure coupled to a corresponding fluid delivery port and coated with an electroactive polymer; a voltage source providing a conductive signal; and an interconnect network that carries the conductive signal to the port gates. In response of the electroactive polymer to the conductive signal, each port gate is selectively operable between a closed mode that prevents transfer of fluid through its corresponding fluid delivery port to the tissue, and an open mode that allows transfer of the fluid through its corresponding fluid delivery port to the tissue.

    摘要： The electrode lead system of a preferred embodiment includes a series of first electrical subsystems; a guiding element that positions the series of first electrical subsystems in a three dimensional arrangement within body tissue; a second electrical subsystem; and at least one connector that couples the first electrical subsystems to the second electrical subsystem. The electrode lead system of another preferred embodiment includes a series of electrode arrays; a guide tube that facilitates implantation of electrode arrays within body tissue and temporarily contains the series of electrode arrays; and a guiding element that provides a bias on the series of electrode arrays such that (a) when contained by the guide tube, the first electrical subsystems maintain a substantially singular path within body tissue, and (b) when not contained by the guide tube, the first electrical subsystems diverge along more than one path into a three dimensional arrangement within body tissue.
