Publication number: 20150061591Abstract: A wireless power system capable of transmitting power through the skin over distances ranging from a few inches to several feet includes an external transmitting coil assembly and a receiving coil assembly. A transmitting resonant coil and a receiving resonant coil are constructed as to have closely matched or identical resonant frequencies so that the magnetic field produced by the transmitting resonant coil is able to cause the receiving resonant coil to resonate strongly also, even when the distance between the two resonant coils greatly exceeds the largest dimension of either coil. The receiving resonant coil then creates its own local time varying magnetic field, which inductively produces a voltage to provide power to an active implantable medical device or implantable rechargeable battery.Type: ApplicationFiled: November 10, 2014Publication date: March 5, 2015Inventors: Randolph K. Armstrong, Greg S. Aber

Patent number: 8901775Abstract: A wireless power system capable of transmitting power through the skin without percutaneous wires over distances ranging from a few inches to several feet includes an external transmitting coil assembly and a receiving coil assembly. The transmitting coil assembly includes an excitation coil and transmitting resonant coil which are inductively coupled to each other. The receiving coil assembly includes a receiving resonant coil and a power pick-up coil which are also inductively coupled to each other. A high frequency AC power input, such as radio frequency (RF), supplied to the excitation coil inductively causes the transmitting resonant coil to resonate resulting in a local time varying magnetic field.Type: GrantFiled: March 2, 2011Date of Patent: December 2, 2014Assignee: Everheart Systems, Inc.Inventors: Randolph K. Armstrong, Greg S. Aber

Publication number: 20140255225Abstract: A flow thru mechanical bearing system can be used in an implantable rotary blood pump that includes a pump housing. An impeller housed in the pump housing can be radially supported by a row of at least three low friction contact points located on an inside bore of the impeller. The impeller may be axially supported by a second mechanical bearing. The second mechanical bearing may provide at least three axial contact points on the top surfaces of the impeller. The impeller is driven by a magnetic coupling which functions mainly to transmit torque to the impeller. Further, in some cases, the magnetic coupling may restrain axial motion of the impeller.Type: ApplicationFiled: March 8, 2013Publication date: September 11, 2014Applicant: EverHeart Systems Inc.Inventors: Greg S. Aber, Allan S. Rhoads

Publication number: 20140200664Abstract: A high efficiency blood pump includes a pump housing, wherein the pump housing provides an inlet and outlet. The pump includes a motor housing, wherein the motor housing contains a motor. An impeller is housed in the pump housing, wherein the impeller is radially supported by a hydrodynamic bearing providing at least one row of pattern grooves. A diaphragm provided by the pump housing separates the impeller chamber from the motor chamber. A magnetic coupling is provided between the motor and the impeller, wherein the magnetic coupling causes the impeller to rotate when the motor rotates and provides axial restraint of the impeller.Type: ApplicationFiled: January 17, 2014Publication date: July 17, 2014Applicant: EVERHEART SYSTEMS INC.Inventors: Neil H. Akkerman, Greg S. Aber

Publication number: 20130345493Abstract: A high efficiency cardiac support system is suitable for chronic use in treating heart failure, wherein the system includes an implantable rotary blood pump, an implantable power module, a wireless power transfer subsystem, a patient monitor, and a programmer. In a cardiac support system, the cumulative efficiencies of the components of the system are capable of providing therapeutically effective blood flow for a typical day of awake hours using the energy from a single wireless recharge of an implanted rechargeable energy source. Moreover, the implantable rechargeable energy source may be recharged during a normal sleep period of 8 hours or less. The system may provide full or partial cardiac support without the need for external wearable batteries, controllers, or cables.Type: ApplicationFiled: September 4, 2013Publication date: December 26, 2013Applicant: EVERHEART SYSTEMS INC.Inventors: Greg S. Aber, Neil H. Akkerman, Randolph K. Armstrong
