摘要： Implantable medical devices (IMDs) are disclosed which are capable of wirelessly receiving power from a magnetic field to power the IMD or charge its battery, but which do not use a wire-wound coil for magnetic field reception. The IMD can include a case housing control circuitry for the IMD, in which at least a portion of the case is conductive, with a case current formed in the conductive case portion in response to the magnetic field. The IMD includes power reception circuitry inside the case, and includes various examples of first and second electrical connections used to divert at least some of the case current as a power current to the power reception circuitry, thus allowing the power reception circuitry to use the power current to provide power to the IMD or to charge its battery.

摘要： Disclosed is an improved external controller useable in an implantable medical device system. The communication coil in the external controller is formed in a printed circuit board (PCB), i.e., by using the various tracing layers and vias of the PCB. As illustrated, the PCB coil is formed at a plurality of trace layers in the PCB, and comprises a plurality of turns at some or all of the layers. The communication coil may wrap around the other circuitry used in the external controller, which circuitry may be mounted to the front and/or back of the PCB. The geometry of the coil is specially tailored to maximize its inductance, and hence maximize its ability to communicate in the sub-4 MHz range which is not significantly attenuated by the human body.

摘要： An improved integrated external controller/charger system useable with an implantable medical device is disclosed. The system comprises two main components: an external controller and an external charging coil assembly that is coupleable thereto. When the external charging coil assembly is coupled to the external controller, the system can be used to both send and receive data telemetry to and from the implantable medical device, and to send power to the device. Specifically, the external controller controls data telemetry by energizing at least one coil within the external controller, and the external controller controls power transmission by energizing a charging coil in the external charging coil assembly, which is otherwise devoid of its own control, power, and user interface. The result is a cheaper, simpler, more compact, and more convenient data telemetry and charging solution for the patient having a medical implant.

摘要： Implantable medical devices (IMDs) are described. The IMDs are configured to wirelessly receive power from an electromagnetic field provided by an external charger. The IMDs include a conductive case and a header that is typically non-conductive, and which houses a three dimensional antenna structure configured to couple with the external magnetic field. Currents induced in the antenna structure are used to provide power to the IMD. The three dimensional antenna structure may be configured as a cage structure comprising a first loop antenna proximate and parallel to the front of the header, a second loop antenna proximate and parallel to the back of the header, and a third loop antenna proximate and parallel to the top of the header. The three dimensional antenna structure allows the IMD to effectively receive power from different directions, for example, if the orientation of the IMD is flipped or otherwise shifted within the patient's body.

摘要： An implantable medical device and external base station system are disclosed. The external base station can provide a passive electric field to power the implant, or to charge its battery. The base station may also power or charge using magnetic fields under certain circumstances. The Implantable medical device may comprise an implantable neurostimulator having a number of electrode leads extending from its body. One or more of the electrode leads can comprise the antenna for receiving the electric field from the base station, and resonance in that antenna can be rectified to provide the power for recharging the battery. Although the E-field provided by the base station does not provide as much power for recharging as does other traditional charging techniques (such as those using magnetic fields), it can occur passively and over longer distances to allow the patent's implant to be recharged when in relative proximity to the base station.

摘要： By incorporating magnetic field sensing coils in an external charger, it is possible to determine the position of an implantable device by sensing the reflected magnetic field from the implant. In one embodiment, two or more field sensing coils are arranged to sense the reflected magnetic field. By comparing the relative reflected magnetic field strengths of the sensing coils, the position of the implant relative to the external charger can be determined. Audio and/or visual feedback can then be communicated to the patient to allow the patient to improve the alignment of the charger.

摘要： An external charging system for an Implantable Medical Device (IMD) is disclosed having a thermal diffuser proximate to the primary charging coil for distributing heat from the primary charging coil. In an example, the primary charging coil is mounted to a first side of a circuit board, and the thermal diffuser is also connected to the first side and in contact with the primary charging coil. In one example, the thermal diffuser is a plastic material, such as an acrylic pad, with a high thermal conductivity and a low electrical conductivity. The thermal diffuser may also contact temperature sensors mounted to the first side of the circuit board.

摘要： A base station for passively recharging a battery in an implant without patient involvement is disclosed. The base station can be hand held or may comprise equipment configured to be placed at a fixed location, such as under a bed, on or next to a wall, etc. The base station can generate electric and magnetic fields (E- field and B-field) that couple with an antenna and a receiving coil within the implant to generate a charging current for charging the implant's battery. No handling or manipulation on part of the patient is necessary; the implant battery is passively charged whenever the patient is within range of either the magnetic or electric charging fields generated by base station. Charging using the B-field occurs when the IPG is at a relatively short distance from the base station, while charging using the E-field occurs at longer distances. Back telemetry from the implant can inform the base station whether B-field or E-field charging is indicated, and is preferred if possible for its ability to transfer higher amounts of power to the implant.

摘要： An improved external charger for a battery in an implantable medical device (implant), and technique for charging batteries in multiple implants using such improved external charger, is disclosed. During charging, values for a parameter measured in the implants are reported from the implants to the external charger. The external charger infers from the magnitudes of the parameters which of the implants has the highest and lowest coupling to the external charger, and so designates those implants as "hot" and "cold." The intensity of the magnetic charging field is optimized for the cold implant consistent with the simulation to ensure that that the cold implant is charged with a maximum (fastest) battery charging current. The duty cycle of the magnetic charging field is also optimized for the hot implant consistent with the simulation to ensure that the hot implant does not exceed the power dissipation limit. As a result, charging is optimized to be fast for all of the implants, while still safe from a tissue heating perspective.
摘要翻译：公开了一种用于可植入医疗装置（植入物）中的电池的改进的外部充电器，以及使用这种改进的外部充电器为多个植入物中的电池充电的技术。在充电期间，在植入物中测量的参数的值从植入物报告给外部充电器。外部充电器从参数的大小推断出植入物具有最高和最低耦合到外部充电器的参数，因此将这些植入物称为“热”和“冷”。对于与模拟一致的冷植入物，磁充电场的强度被优化，以确保冷植入物以最大（最快）的电池充电电流充电。对于与模拟一致的热注入，磁充电场的占空比也被优化，以确保热植入不超过功率耗散极限。因此，对于所有植入物，充电被优化为快速，同时从组织加热的角度来看仍然是安全的。
