Abstract: Systems and methods for deploying and securing conductive materials to a region of tissue may utilize a catheter. The catheter may provide a tip with one or more detachable sections or may provide an adjustable opening. A lumen of the catheter may provide a conductive material, such as a filament, fiber, network or patch of carbon nanotubes (CNTs) or carbon nanofibers (CNFs). In some embodiments, the conductive materials may be coupled to securing mechanisms, such as screws, clips, anchors, alligator clips, or anchors with barbs, which can be actuated to attach the conductive materials to desired regions of tissue. In some embodiments, the catheter may provide a needle tip that allows the conductive material to be embedded into desired regions of tissue by inserting the needle into the tissue.

Abstract: Articles comprising neat, aligned carbon nanotubes and methods for production thereof are disclosed. The articles and methods comprise extrusion of a super acid solution of carbon nanotubes followed by removal of the super acid solvent. The articles may be processed by wet-jet wet spinning, dry-jet wet spinning, and coagulant co-flow extrusion techniques.
