摘要： High reliability electrical connections between a helical strand and flat electrodes, such as strip electrodes found in implantable neurostimulator systems, are described. The connection consists of a crimp joint in which an inside diameter mandrel is used to provided the coil with sufficient radial rigidity to ensure structural integrity of the crimp. The mandrel is made of a relatively soft biocompatible material that deforms rather than damages the fine wires of the helical strand during crimping. The crimp is accomplished by radial deformation of an annular or semi-annular crimping member that receives the helical strand/mandrel assembly.

摘要： Coatings for implantable electrodes consisting of single- or multi-walled nanotubes, nanotube ropes, carbon whiskers, and a combination of these are described. The nanotubes can be carbon or other conductive nanotube-forming materials such as a carbon-doped boron nitride. The nanotube coatings are grown “in situ” on a catalytic substrate surface from thermal decomposition, or they are bonded to the substrate using a metal or conductive metal oxide thin film binder deposited by means of a metal compound precursor in liquid form. In the latter case, the precursor/nanotube coating is then converted to a pure metal or conductive metal oxide, resulting in the desired surface coating with imbedded nanotubes.

摘要： A vascular stent comprising a drug-eluting outer layer of a porous sputtered columnar metal having each column capped with a biocompatible carbon-containing material is described. This is done by placing the stent over a close-fitting mandrel and rotating the assembly in a sputter flux. The result is a coating that is evenly distributed over the outward-facing side of the stent's wire mesh while preventing the sputtered columnar coating from reaching the inward facing side where a smooth hemocompatible surface is required. The stent is then removed from the mandrel, exposing all surfaces, and finally coated with a layer of carbon such as amorphous carbon or diamond-like carbon. The carbonaceous coating enhances biocompatibility without preventing elutriation of a therapeutic drug provided in the porosity formed between the columnar structures. The result is a stent that is adapted to both the hemodynamic and the immune response requirements of its vascular environment.

摘要： Implantable electrical lead wires, such as cobalt-chromium-molybdenum alloy wires, are coated with a metal, ceramic, or carbon to a thickness of about 100 nm or less to provide a non-reactive interface to polyurethane sheathing materials. Preferred is sputter coating an amorphous carbon intermediate the alloy wire and the polyurethane sheath.
