Definitions
- the present invention relates to a transcutaneous energy transfer (TET) system and a TET system method of operation.
- TET transcutaneous energy transfer
- the implanted battery may be required to supply the implanted device ' s entire power demand for one to several hours at a time, such as when the patient does activities that preclude wearing the external TET power unit, such as showering or swimming.
- the battery capacity is large and can meet the power demand for the required amount of time.
- the implanted battery's capacity decreases. With decreased battery capacity, the patient cannot spend as much time without the external TET power unit. Eventually, the battery may need to be replaced so that the patient can go without the external TET power unit for long enough periods of time again.
- a TET system for powering an implanted electrical device.
- a circulatory assist device can be provided which can include one or more electrical devices such as a pump having an electric motor, the pump having a power demand which varies with the cardiac cycle of a patient in which the pump is implanted.
- An implantable power unit is adapted for mounting within the body of the patient.
- the power unit may have a secondary coil and a power circuit connected to the secondary coil for controlling and supplying power to controlling circuitry and to the pump, for example. In that way, power can be received at the secondary coil and applied to controlling circuitry and to the pump.
- a monitoring circuit of the implantable power unit can be used to monitor a condition of the power circuit.
- the monitoring circuit can transmit a transcutaneous telemetry signal which represents the monitored condition for use by a control circuit of an external unit to adjust power transmission.
- An external power supply may be adapted for transcutaneous inductive coupling with the secondary coil, and may have a drive circuit operable to apply an alternating current to the primary coil, and a control circuit operable to receive the telemetry signal and adjust the alternating current in the primary coil at least in part in response to the telemetry signal.
- the monitoring circuit and control circuit may be operable to monitor the condition of the power circuit and adjust the alternating current in the primary coil in accordance therewith. In that way, the alternating current in the primary coil may be varied substantially in accordance with the cardiac cycle.

- FIG. 1 schematically illustrates a transcutaneous energy transfer (TET) system 100 used to supply power to an implanted therapeutic electrical device 102 in an internal cavity within the body, i.e., below the skin of a patient 104.
- the implanted electrical device 102 can include a pump such as for use in pumping blood as a ventricular assist device ("VAD"), for example.
- VAD ventricular assist device
- the implanted electrical device 102 can include controlling circuitry to control, for example, a pump.
- the TET system 100 includes an external module 110 having a primary power coil 114, associated circuitry 116 and terminals 111 for receiving an external source 112 of power.
- An internal module 120 implanted underneath the skin of the patient 104 has a secondary power coil 124, associated circuitry 126 and an output cable for supplying power to the implanted electrical device 102.
- Power is transferred from the primary coil 114 to the secondary coil 124 by means of inductive coupling, i.e., via near-field interaction of a magnetic field overlapping the primary 114 and secondary 124 coils.
- the voltage across each coil can be large, for example, peak-to-peak voltages of 100 V to 400 V are not uncommon.
- the implanted module 120 is also connected to an implanted battery 128 for supplying power to the implanted electrical device 102 in case power to the external module 110 when power transmission is interrupted between the external 110 and implanted 120 modules. With the implanted battery 128 as a backup, the external TET module 110 can be disconnected when the patient bathes or performs other activities .
- FIG. 2 is a functional block diagram illustrating electrical components of the TET system 100.
- the external module 110 of the TET system 100 includes the primary coil 114 and associated circuitry including a microcontroller 212, a radio frequency ("RF") telemetry system 214 and a TET driver 216.
- the primary coil 114 can be fabricated using Litz wire, in which the primary coil 114 is made up of relatively thin, insulated wires twisted or woven together in groups. Power transfer from an external power source 112 to the implanted module 120 is provided through the TET driver 216 as controlled by microcontroller 212.
- the implanted module 120 includes a TET receiver 226 including the secondary coil 124, a microcontroller 222 and an RF telemetry system 224. Like the primary coil 114, the secondary coil 124 can also be fabricated using Litz wire.
- the TET receiver 226 includes rectifier circuitry, such as a diode bridge, for converting electrical energy at the secondary coil in alternating current (“AC") form into direct current (“DC”) form. DC power output from the TET receiver 226 is supplied to a microcontroller 222 of the implanted module 120, an implanted battery 128 and an implanted electrical device 102.
- the implanted electrical device 102 can include one or more of a variety of devices such as a VAD blood pump, for example, which has power demands which could not be supplied by the implanted battery 128 for long periods of time.
- the implanted battery 128 is not a primary power source, but is used to supply power for relatively short periods of time in case of an interruption in the transmission of power to the implanted module 120.
- the implanted module 120 can rely on battery power when the patient takes a shower .
- FIG. 3 is a block and schematic diagram illustrating operational components of the external module 110 in greater detail.
- a power management module 314 under control of microcontroller 212 transfers power in DC form to a variable output level power supply 316 from one or more external power sources 312a, 312b.
- the external power sources 312a, 312b can include one or more batteries, or one battery and an external AC/DC converter coupled to an AC source (such as a wall outlet) or a DC source, such as from within an automobile, for example.
- the power management module 314 regulates the flow of power from the one or more external power sources 312a, 312b to a variable output power supply 316.
- This power module 314 has terminals 334a for connection with a first external power source 312a and has terminals 334b for connection with a second external power source 312b.
- the power module 314 may have more sets of terminals (not shown) for connection with power sources (not shown) other than sources 312a, 312b.
- the power management module 314 can determine which particular sources or types of sources are connected thereto and may also detect to which sets 334a, 334b of terminals the power sources 312a, 312b are connected.
- Module 314 determines whether or not power sources are connected thereto and may also determine the status of each connected power source, i.e., the voltages of each power source and the charge state of battery power sources.
- the power management module 314 also selects one or more of several connected power sources to draw power from in supplying energy to drive the TET system 100. For example, when both a battery and an AC or DC power source other than a battery are connected, power module 314 may use the AC or DC power as a primary source to power the external TET 110 and hold the battery in reserve for use in case the primary source becomes disconnected.
- the power management module 314 can also be used to regulate the flow of a charging current to one of the external power sources 312a, 312b, such as when the second power source 312b is a battery.
- the variable power supply 316 provides power to a TET driver 318 at a rate which is subject to vary in accordance with the time-varying need for power of the electrical implanted therapeutic device 102 (FIG. 2).
- the power transfer rate to the TET driver 318 can be varied by modifying the voltage Vs at which power is output by the power supply 316 under control of one or more signals output by microcontroller 212.
- the output voltage Vs can be varied between 13 V and 25 V, in order to adjust between varying power demands and supply power efficiently to the TET driver 318.
- the TET driver 318 supplies an excitation current to the primary coil 114 for transferring power to the implanted TET module 120.
- the TET driver 318 receives power at a steady (DC) supply voltage Vs and generates a magnetic flux for power transmission which has an AC waveform at a relatively low radio frequency (RF) .
- RF radio frequency
- the frequency of the AC power transmission waveform is set between about 30 kilohertz (kHz) and 300 kilohertz.
- Power is transmitted by inductive near-field coupling between the primary coil 114 and the secondary coil 124 (FIG. 2) of the implanted module 120.
- the primary coil 114 is connected in series with a capacitor 330 in a tank circuit 331.
- the tank circuit 331 resonates at a resonant frequency determined by the inductance value of the coil 114 and the capacitance value of capacitor 330.
- the TET driver 318 includes a set of power-rated field effect transistors in an H-bridge arrangement, e.g., MOSFETs, which drive the primary coil 114 in a push-push fashion under control of logic drive circuits .
- the TET driver 318 can regulate the transfer of power between the primary coil 114 and the secondary coil 124 (FIG. 2) in three ways.
- the TET driver 216 can output an excitation current to the primary coil 114 in a pulsed manner and vary the width of the drive pulses supplied to the coil 114 and hence, the duty cycle of such pulses.
- the TET driver 216 can also vary the frequency at which drive pulses are supplied to the primary coil 114 to create a desired balance between efficiency of power transfer throughout the system and stability of power regulation in the system.
- the supply voltage Vs at which power is provided to the H-bridge circuit can be varied.
- a peak current is required to drive the motor stator of the VAD once during each cardiac cycle of pumping blood from the left ventricle into the aorta to pressurize the blood flowing into the aorta.
- the peak current is substantially greater than a reduced current value ("R") which is needed to drive the motor stator of the VAD at another time once during each cardiac cycle.
- FIG. 7 indicates sampling intervals in which the voltage level Vtet is sampled.
- the voltage level is sampled 50 or more times per cardiac cycle, i.e., at the rate of 50 or more times per beat when the heart is beating at a rate of once per second, i.e., at 60 beats per minute. Therefore, FIG. 7 indicates that the voltage level has been sampled already 200 times by the time that one cardiac cycle ("T") has ended.
- the backup telemetry module 402 may include a radio frequency (RF) transmitter for transmitting signals to the external module 110 (FIG. 3) .
- the backup telemetry module 402 can operate without having a coil (e.g., such as coil 406; FIG. 4) being inductively coupled with a primary coil 114 in the external module 110.
- the RF transmitter of the backup telemetry module 402 can be designed to transmit signals over a frequency range different from that used by the primary RF transmitter 224 and avoid interference which affects the primary RF transmitter 224.
