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.
摘要翻译：公开了一种用于对植入物中的电池进行无源再充电的基站，无需患者参与。基站可以是手持的，或者可以包括被配置为被放置在固定位置的设备，例如在床下面，在墙壁上或墙壁上等。基站可以产生电场和磁场（E-场和B 场），其与植入物内的天线和接收线圈耦合，以产生用于对植入物的电池充电的充电电流。不需要对部分患者进行处理或手术; 每当患者处于由基站产生的磁性或电荷充电场的范围内时，植入物电池被动地充电。当IPG距离基站相对较短的距离时，使用B场进行充电，而使用电场进行充电会发生较长的距离。来自植入物的反向遥测可以通知基站是否指示B场或E场充电，并且如果可能的话将其更大量的功率传送给植入物是优选的。

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.
摘要翻译：公开了可植入医疗装置和外部基站系统。外部基站可以提供无源电场来为植入物供电，或为其电池充电。在某些情况下，基站也可以使用磁场进行供电或充电。植入式医疗装置可以包括具有从其主体延伸的多个电极引线的可植入神经刺激器。电极引线中的一个或多个可以包括用于从基站接收电场的天线，并且该天线中的谐振可被整流以提供用于为电池再充电的电力。虽然由基站提供的电场不像其他传统的充电技术（例如使用磁场的那些）那样提供充电的功率，但它可以被动地和超过更长的距离发生，以允许专利的植入物被充电，在相对靠近基站。

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。在充电过程中，植入物中测量的参数值将从植入物报告给外部充电器。外部充电器根据参数的大小推断哪些植入物与外部充电器具有最高和最低的耦合，并且因此将这些植入物指定为“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）电池充电电流充电。磁充电场的占空比也针对与仿真一致的热注入进行优化，以确保热注入不超过功耗限制。因此，对于所有植入物来说，充电都经过优化，以便从组织加热的角度来看仍然安全。

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.
