Patent number: 10561775Abstract: A system for alerting a patient includes a ventricular assist device (VAD), a battery, and an alarm system. All of these components of the system are configured to be implanted within the patient. The implanted alarm system is configured to provide an alert to and from within the patient based on a condition. The alert can be a vibration or an electrical shock, and the condition can be the implanted battery being below a threshold, a failure of the implanted battery, an error of the implanted battery, or an error of the implanted VAD.Type: GrantFiled: July 6, 2018Date of Patent: February 18, 2020Assignee: Leviticus Cardio Ltd.Inventor: Michael Zilbershlag

Patent number: 10543303Abstract: Multi-cell battery packs can be made safer with certain features that mitigate the consequences of cell failure. Parameters of a cell are monitored to determine when the cell should be disconnected from the pack in case of a fault. The battery is reconfigured to continue operating in a safer mode. An over-charging prevention system reduces the maximum voltage that remaining battery pack can be charged to, so that the cells do not overcharge. Additional circuitry allows the disconnected cell to be periodically reconnected to the battery pack to determine if its conditions have sufficiently improved. The cells also include components for self-powering these cell functions while it is disconnected from the rest of the circuit.Type: GrantFiled: September 22, 2017Date of Patent: January 28, 2020Assignee: Leviticus Cardio Ltd.Inventors: Michael Zilbershlag, Neri Naveh, Roni Daffan

Patent number: 9793579Abstract: The present disclosure provides devices, systems, and methods for identifying conditions in a battery that predict fault or failure, alerting a user to the condition, and providing solutions to mitigate the potential harm that would otherwise result from the fault or failure. Further provided are battery casing designs for improved safety. These systems, devices, and methods are applicable to batteries generally, and are particularly useful in the field of implanted medical devices for mitigating the dangers of battery faults or explosions occurring within the body.Type: GrantFiled: November 7, 2014Date of Patent: October 17, 2017Assignee: Leviticus Cardio Ltd.Inventor: Michael Zilbershlag

Patent number: 9786432Abstract: An external transmitter inductive coil can be provided in, on, or with a belt designed to be placed externally around a part of a body of a patient. An implantable device (such as a VAD or other medical device) that is implanted within the patient's body has associated with a receiver inductive coil that gets implanted within that part of the patient's body along with the device. The externally-located transmitter inductive coil inductively transfers electromagnetic power into that part of the body and thus to the receiver inductive coil. The implanted receiver inductive coil thus wirelessly receives the inductively-transferred electromagnetic power, and operates the implant.Type: GrantFiled: April 13, 2016Date of Patent: October 10, 2017Assignee: Leviticus Cardio Ltd.Inventor: Michael Zilbershlag

Patent number: 8961389Abstract: This embodiment suggests new approach for Endovascular Ventricular Assist Device, using the mathematical objective & principle of superposition allow design and calculation of the body response to VAD pump located in the Aorta. This new approach allows minimal invasive Endovascular VAD that result in similar relief to the heart as partial VAD. Using special power transfer technique will allow wireless power transformation into the aorta.Type: GrantFiled: August 14, 2014Date of Patent: February 24, 2015Assignee: Leviticus Cardio Ltd.Inventor: Michael Zilbershlag

Patent number: 8845510Abstract: Systems and methods of the invention generally involve a convertible power transfer system for supplying wireless energy to an implant. According to certain aspect, a system of the invention includes a convertible inductive coil and a receiver inductive coil. The convertible inductive coil may be disposed externally on a body of a patient and to inductively transmit electromagnetic power. The convertible inductive coil transitions between direct electromagnetic power transfer and passive electromagnetic power transfer. The receiver inductive coil can be implanted within the body and provides received electromagnetic power to the implant. The convertible inductive coil, during passive electromagnetic power transfer, couples to the receiver inductive coil such that the convertible inductive coil and receiver inductive coil operate together as single receiver inductive coil that receives inductively transferred electromagnetic power from a distant transmitter inductive coil.Type: GrantFiled: December 5, 2013Date of Patent: September 30, 2014Assignee: Leviticus Cardio Ltd.Inventor: Michael Zilbershlag

Patent number: 8075472Abstract: The invention is a kit for a permanent ventricular assist device that can be permanently implanted into the circulatory system of a patient. The kit comprises one or more passive cores (Pcore), a stator, a power supply, and a controller unit. The inventors have realized that major open heart surgery, generally used for implementing a magnetic blood pump in the circulatory system, can be wholly avoided if the rotor and the stator are physically separated and are implanted respectively inside and around the blood vessel at the location of interest. Therefore the kit is characterized in that the one or more Pcores are configured to allow them to be implanted inside a blood vessel and the stator is configure to enable it to be placed outside of the blood vessel surrounding the Pcores. Also described are illustrative medical procedures for implanting the components of the kit at different locations in the body.Type: GrantFiled: May 4, 2008Date of Patent: December 13, 2011Assignee: Leviticus-Cardio Ltd.Inventors: Michael Zilbershlag, Moshe Levy
