Abstract: Systems and methods are provided for fabricating carbon nanostructures by low voltage near-field electromechanical spinning (LV-NFEMS). Processes described herein can produce ˜2-5 nm carbon nanowires with ultrahigh electrical conductivity using top-down and controlled reductive techniques from a polymer. Configurations are also provided to allow for deposition control and fiber elongation/alignment. One embodiment uses a low voltage near-field electromechanical spinning process to produce a polymer fiber from a polymer solution. Another embodiment of the method uses pyrolysis to convert the produced polymer fiber into a ˜2-5 nm carbon nanowire. System configurations provide advancements in polymer droplet control and control of a sustained jet of polymer solution with the use low voltages. Systems and processes described herein can include use of an array of polymer precursor nanofibers suspended onto a silicon substrate and converted to carbon nanowires.

Abstract: Anchoring devices for affixing an implanted lead at a target location in a patient are provided herein. Such anchoring devices include a helical body having a plurality of tines extending laterally outward from the lead when deployed that engage tissue to inhibit axial movement of the implanted lead. The plurality of tines are biased towards the laterally extended deployed configuration and fold inward towards the lead to a delivery configuration to facilitate delivery of the lead through a sheath. The tines may be angled in a proximal direction or in both proximal and distal directions and may include various features to assist in visualization and delivery of the lead.
