Abstract: The present disclosure relates to a module (110) for relaying power wirelessly to a device implanted in a user (104). The module may include a structure (115) adapted to be worn by the user, a receiver (212) configured to receive a first wireless power transmission at a first frequency, a transmitter (216) configured to transmit a second wireless power transmission at a second frequency different from the first frequency, and a frequency changer (218) configured to convert energy generated by the first wireless power transmission into energy for generating the second wireless power transmission. Each of the receiver, transmitter and frequency changer may be disposed on or in the structure.

Abstract: A method for monitoring a charge of a battery in a device, comprising providing a low power processor having a wake state and a dormant state, the low power processor configured to periodically change from the dormant state to the wake state. The method further comprises periodically enabling a battery monitor circuit to determine the charge of the battery, the low power processor enabling the battery monitor circuit when the low power processor is in the wake state. The battery monitor circuit has a default safe state in which a digital processor enables the battery monitor circuit and a normal operating state in which the low power processor periodically enables the battery monitor circuit, the battery monitor circuit switching from the default safe state to the normal operating state when the low power processor is detected. The digital processor is different than the low power processor.

Abstract: An axial-flow blood pump for pumping blood includes a substantially cylindrical outer enclosure. A tubular housing concentric with and located within the outer enclosure has at one end an inlet and at an opposite end an outlet. A motor stator is concentric with and located between the outer enclosure and the tubular housing. An impeller is concentric with and located within the tubular housing. The impeller is suspended in operation by a combination of passive magnetic forces between magnets within the impeller or magnetized regions of the impeller and the motor stator and hydrodynamic thrust forces generated as blood flows between the tubular housing and a plurality of hydrodynamic thrust bearing surfaces located on the impeller. A volute may be in fluid-tight connection with the outlet of the tubular housing for receiving blood in the axial direction and directing blood in a direction normal to the axial direction. The volute has a flow-improving member extending axially from the volute and into and coaxially with the tubular housing.

Abstract: A method of estimating the blood flow rate of a heart ventricle assist device which is positioned externally of, or implanted in, a patient. The assist device comprises a blood pump having a rapidly rotating, electrically powered impeller, and comprises briefly interrupting power to the impeller to cause its rotation to slow. From this, blood viscosity can be estimated, which viscosity is used to obtain real time, estimated blood flow rates and pressure heads. Apparatus for accomplishing this is disclosed.

Abstract: A system, comprising an implantable electrical device adapted for mounting within the body of the patient, and an implantable power unit adapted for mounting within the body of the patient, the power unit having a receiving coil, a power circuit connected to the receiving coil so that power applied to the receiving coil can be transmitted to the implantable device. The system further comprising an external power supply having a transmitting coil adapted for transcutaneous inductive coupling with the receiving coil to define a system having a resonant frequency varying in relation to a distance between the transmitting and receiving coils, a drive circuit operable to apply an alternating current to the transmitting coil at a variable drive pulse width. A control circuit is operable to (i) monitor a parameter related to mutual inductance between the transmitting and receiving coils; and (ii) adjust the variable transmission frequency to a value having a predetermined difference from the resonant frequency, so as to maintain the transmission frequency with a predetermined difference from the resonant frequency. The power circuit further includes a battery and a routing circuit arranged to route power from the receiving coil to the implantable device to the battery or both when power is received through the receiving coil and from the battery to the implantable device when power is not received by the receiving coil, the control circuit being operable to vary the current in the transmitting coil so as to maintain the monitored parameter within the desired range during the charging operation and during operation when the battery is fully charged
