摘要： Techniques for recharging a rechargeable power source coupled to a secondary coil implanted within a living body are described. In one embodiment, a recharging device external to the living body induces a sequence of pulses in a primary coil that is coupled to the secondary coil. The sequence includes high-amplitude pulses alternating with low-amplitude pulses, each high-amplitude pulse having an amplitude selected to transfer charge to the rechargeable power source during times of poor coupling between the primary coil and the secondary coil, each low-amplitude pulse having an amplitude selected to transfer charge to the rechargeable power source during times of good coupling between the primary coil and the secondary coil, and wherein the sequence of pulses is selected to prevent a violation of a limiting condition such as heating that is associated with recharging the rechargeable power source in an open-loop manner.

摘要： Techniques associated with a universal recharging device for recharging a power source of implantable medical devices (IMDs). The recharging device includes an interface to allow an antenna assembly to be removably coupled. The antenna assembly has a primary coil and a corresponding sense coil. The sense coil has a configuration that is selected based on the configuration of the primary coil. The sense coil is adapted to prevent voltage across the primary coil from exceeding a maximum voltage amplitude allowable with the recharging device. The maximum voltage amplitude may be selected based on a maximum magnetic field strength to which a patient is to be exposed. In one embodiment, the maximum voltage amplitude is programmable.

摘要： A patient programmer for facilitating patient control over an implanted medical device, such as an implanted spinal cord stimulator or the like, is disclosed. A programmer in accordance with the present invention is a portable, light-weight, easy to use patient programmer. The programmer enables a patient to control the operation of his or her implanted device outside of a clinical setting. The programmer incorporates features which ensure that users of varying ages, education levels, dexterity levels, physical and mental health will be able to safely control the operation of their implanted devices, within predefined limits established by a physician or clinician. Circuitry is provided for avoiding battery depletion and/or undesired programmer/implanted device communication in the event that the programmer's key is accidentally depressed (for example, due to being jammed into a purse or pocket) or is depressed repeatedly or continuously over an extended period of time. The programmer provides tactile, audible, and visible feedback to the user to convey information regarding the proper (or improper) operation of the programmer and the implanted device. In one embodiment, the device includes a beeper and light-emitting diodes (LEDs) to indicate, for example, that a desired programming function has been successful or unsuccessful.

摘要： Techniques adapted for use with recharging a rechargeable power source of an implantable device. One aspect relates to providing a flexible primary coil that can be transcutaneously coupled to a secondary coil of the implantable device. Multiple adjacent turns of the coil are grouped via lacing to form bundles. The bundles have at least one dimension that is selected to be a same size as a predetermined thickness of the coil. In one embodiment, the dimension is a diameter of the bundle. In another embodiment, the dimension is at least one of a length or width of the bundle. Insulating overmolding may be provided over the coil. In one embodiment, the resulting antenna structure is bidirectional such that substantially the same performance characteristics are obtained during recharge regardless of which of two major surfaces of the antenna is placed in proximity to the patient.

摘要： Systems and methods for orienting a medical instrument relative to at least a portion of a medical device include a first tilt detector (62) associated with the medical instrument and a second tilt detector (58) associated with the medical device (12). The first tilt detector may be within an orientation device (60) that is coupled to or separate from the medical instrument. The tilt detectors generate signals that may be used to determine the relative orientation between at least a portion of the medical device and medical instrument. For example, in some embodiments, the signals may be used to determine whether the orientations of the refill port of an implantable medical device and the medical instrument substantially match.

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： Techniques are disclosed for recharging an Implantable Medical Device (IMD). In one embodiment, a first external coil is positioned on one side of a patient's body, such as on a front side of the torso in proximity to the IMD. A second external coil is positioned on an opposite side of the patient's body, such as on the back of the torso. A recharging device generates a current in each of the coils, inductively coupling the first and the second coils to the secondary recharge coil of the IMD. According to another aspect, each of the two external coils may wrap around a portion of the patient's body, such as the torso or head, and are positioned such that the IMD lies between the coils. According to this aspect, current generated in the coils inductively couples to a second recharge coil that is angled within the patient's body.
