    Abstract: Some embodiments of the present disclosure pertain to methods of improving electrical conduction across an impaired region of a tissue (e.g., myocardial tissue) by applying an electrically conductive material (e.g., carbon nanotube fibers) across the impaired region. The electrically conductive materials can become associated with non-impaired regions of the tissue on opposite sides of the impaired region by suturing. Such methods can also be utilized to treat or prevent cardiac arrhythmia in a subject (e.g., ventricular arrhythmia). Additional embodiments of the present disclosure pertain to electrical wirings that include carbon nanotubes, such as carbon nanotube fibers. Such electrical wirings can be used to transmit electrical signals to a tissue or sense electrical signals from the tissue. In some embodiments, the present disclosure also pertains to suture threads that include carbon nanotubes, such as carbon nanotube fibers.

    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.
