摘要： A charging system for an implantable medical device having a secondary coil. The charging system includes an external power source having at least one primary coil, a modulation circuit operatively coupled to the primary coil and capable of driving it in a manner characterized by a charging parameter, and a sensor in communication with the modulation circuit and capable of sensing a condition indicating a need to adjust the charging parameter during a charging process. The parameter may be varied so that data sensed by the sensor meets a threshold requirement, which may be based on a patient preference, a government regulation, a recommendation promulgated by a health authority and/or a requirement associated with another device carried by the patient. In one embodiment, the regulation dictates maximum magnetic field exposure, and a field limiting circuit is employed to adjust the charging process.

摘要： Implantable medical leads and systems utilize reflection points within the lead to control radio frequency current that has been induced onto one or more filars. The radio frequency current may be controlled by the reflection points to block at least some of the radio frequency current from reaching an electrode of the lead and to dissipate at least some of the radio frequency current as heat on the filar. Controlling the radio frequency current thereby reduces the amount that is dissipated into bodily tissue through one or more electrodes of the lead and reduces the likelihood of tissue damage. The reflection points may be created by physical changes such as to material or size in the filar and/or in insulation layers that may be present such as an inner jacket about the filar and an outer jacket formed by the body of the lead.
