|20150262733||DURABLE FINE WIRE ELECTRICAL CONDUCTOR SUITABLE FOR EXTREME ENVIRONMENT APPLICATIONS - Durable fine wire electrical conductors are robust, durable, small in profile, and light weight, yet capable of operating under extreme environmental conditions. Formed of a glass, silica, sapphire or crystalline quartz fiber core with a metal coating and one or more polymer layers, a unipolar electrical conductor can have an outer diameter as small as about 300 microns or even smaller. The metal buffer coating may be deposited directly on the glass/silica fiber, or upon an intermediate layer between the glass/silica fiber and metal, consisting of carbon and/or polymer. The resulting metallized glass/silica fibers are extremely durable, can be bent through small radii and will not fatigue even from millions of iterations of flexing. Bipolar electrical conductors can include several insulated metallized glass/silica fibers residing side by side, or can be coaxial with two or more insulated metal conductive paths. An outer protective sheath of a flexible polymer material can be included.||09-17-2015|
|20140155948||OPTICAL FIBER-FINE WIRE LEAD FOR ELECTROSTIMULATION AND SENSING - Various aspects of the present disclosure are directed toward an implantable electrostimulation device, a plurality of sensing and pacing elements, and a fine wire lead extending in a sealed relationship from the electrostimulation device and to the plurality of sensing and pacing elements. The fine wire lead includes multiple discrete conductors and a drawn silica or glass fiber core, a polymer cladding on the drawn silica or glass fiber core, and a conductive metal cladding over the polymer cladding. Additionally, the fine wire lead simultaneously delivers different electrical signals or optical signals between the sensing and pacing elements and the electrostimulation device.||06-05-2014|
|20140114384||IMPLANTABLE FINE WIRE LEAD FOR ELECTROSTIMULATION AND SENSING - A cardiac pacemaker or other implantable electrostimulation device has one or more durable fine wire leads to the heart or other electrostimulation site. The lead is formed of a core of silica or glass fiber or similar material, with a protective coating preferably including a metal buffer for conduction. The lead can be unipolar or bipolar (or even with three or more conductors), of small diameter and preferably with an anchoring configuration at the distal end of the lead. The anchor feature can take any of several nonlinear forms such that once implanted in a constrained configuration, the anchor can be released to the expanded, nonlinear configuration. The electrostimulation leads of the invention are extremely durable, can be bent through small radii and can exhibit long life without fatigue failure.||04-24-2014|
|20130041447||DURABLE FINE WIRE LEAD FOR THERAPEUTIC ELECTROSTIMULATION AND SENSING - A cardiac pacemaker, other CRT device or neurostimulator has one or more fine wire leads. Formed of a glass, silica, sapphire or crystalline quartz fiber with a metal buffer cladding, a unipolar lead can have an outer diameter as small as about 300 microns or even smaller. The buffered fibers are extremely durable, can be bent through small radii and will not fatigue even from millions of iterations of flexing. Bipolar leads can include several conductors side by side within a glass/silica fiber, or can be concentric metal coatings in a structure including several fiber layers. An outer protective sheath of a flexible polymer material can be included.||02-14-2013|
