Publication number: 20160354601Abstract: As described herein a CRT delivers high energy pulses via a durable fine wire lead formed of a glass, silica, sapphire or crystalline quartz fiber core with a metal coating. A unipolar electrical conductor can have an outer diameter of about 150 microns or even smaller. The buffered fibers support conduction of high intensity electrical pulses as required for internal or external defibrillators, or other biomedical applications, as well as non-medical applications. Defibrillation pulses can be transmitted through less cross-sectional area of metal in the subject fine wire conductor than would be the case with conventional solid core metal wires. Multiple such coated fibers can act as a single conductor. An outer protective sheath of a flexible polymer material can be included.Type: ApplicationFiled: August 17, 2016Publication date: December 8, 2016Applicant: NuAx, Inc.Inventors: Robert G.

Patent number: 9478327Abstract: 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.Type: GrantFiled: February 19, 2014Date of Patent: October 25, 2016Assignee: NuAx, Inc.Inventors: Robert G.

Publication number: 20150209576Abstract: Implantable medical devices intended for electrostimulation and sensing devices typically incorporate one or more electrical conductors as leads for electrical stimulation to, or retrieval of localized sensing data from, discrete points in the body, such as the heart. Certain applications require delivery of high intensity electrical pulses, i.e. CRTs, or defibrillators. As described herein a CRT delivers high energy pulses via a durable fine wire lead formed of a glass, silica, sapphire or crystalline quartz fiber core with a metal coating. A unipolar electrical conductor can have an outer diameter of about 150 microns or even smaller. The buffered fibers support conduction of high intensity electrical pulses as required for internal or external defibrillators, or other biomedical applications, as well as non-medical applications.Type: ApplicationFiled: January 27, 2014Publication date: July 30, 2015Inventors: Robert G.

Patent number: 9005109Abstract: A cardiac constraint device comprising a jacket of biological compatible material and an adjustment member. The jacket is adapted to be secured to the heart to snugly conform to an external geometry of the heart and assume a maximum adjusted volume to constrain circumferential expansion of the heart beyond the maximum adjusted volume during diastole and to permit unimpeded contraction of the heart during systole. The adjustment mechanism is configured to alter the internal volume defined by the jacket after the jacket is secured to the heart. The invention also provides a method for treating cardiac disease.Type: GrantFiled: April 15, 2011Date of Patent: April 14, 2015Assignee: Mardil, Inc.Inventors: J. Edward Shapland, Robert G.

Patent number: 8870744Abstract: A device for delivery of a cardiac support device for treating cardiac disease of a heart includes a multistage deployment mechanism and an actuating mechanism for controlling the positions of the deployment mechanism. The deployment mechanism is operable to change between a retracted state and an extended state, and includes a plurality of independent stages, including, in one embodiment, a first stage including a guide structure for location adjacent a portion of the patient's heart when in the extended state. A second stage is movably coupled to the first stage, and is guided by the guide structure between the retracted and extended states. The second stage further releasably engages and supports the cardiac support device and positions the cardiac support device at the desired implantation location, guided by the guide structure of the stage. In some embodiments, the deployment mechanism may include additional stages.Type: GrantFiled: April 21, 2010Date of Patent: October 28, 2014Assignee: Mardil, Inc.Inventors: Aaron J.
