摘要： An implantable medical device (IMD) may include a plurality of coils that may be used to recharge a power supply of the IMD and/or provide telemetry for the IMD. The IMD may be configured to couple all of the coils in series, such that currents that are induced by each of the coils are added together when the IMD is exposed to an electromagnetic field. The IMD may be configured to alter the coupling of the coils such that the coils are coupled in series opposition, such that currents that are induced by some coils of the IMD are opposed by currents that are induced by other coils of the IMD.

摘要： A method for subcutaneously treating pain in a patient includes first providing a neurostimulator with an IPG body and at least a primary, a secondary, and a tertiary integral lead with electrodes disposed thereon. A primary incision is opened to expose the subcutaneous region below the dermis in a selected portion of the body. A pocket is then opened for the IPG through the primary incision and the integral leads are inserted through the primary incision and routed subcutaneously to desired nerve regions along desired paths. The IPG is disposed in the pocket through the primary incision. The primary incision is then closed and the IPG and the electrodes activated to provide localized stimulation to the desired nerve regions and at least three of the nerves associated therewith to achieve a desired pain reduction response from the patient.

摘要： An implantable medical device system receives a cardiac electrical signal produced by a patient's heart and comprising atrial P-waves and delivers a His bundle pacing pulse to the patient's heart via a His pacing electrode vector. The system determines a timing of a sensed atrial P-wave relative to the His bundle pacing pulse and determines a type of capture of the His bundle pacing pulse in response to the determined timing of the atrial P-wave.

摘要： An implantable medical device (IMD) with a receiving coil for wireless power transfer. The receiving coil may be disposed about a flux concentrator located in a housing of the IMD. The flux concentrator may concentrate non-radiative near-field energy through the receiving coil. In some cases, the near-field energy may be captured and converted into electrical energy that may be used to recharge a rechargeable power source of the IMD.

摘要： A passive electronic resonator can be configured with a resonant frequency that changes according to changes in the permittivity of a surrounding environment. A wireless device can then wirelessly measure the formation of a biological deposition such as thrombosis or biofilm on the resonator by wirelessly measuring changes in the resonant frequency reflected in corresponding changes to a driving point impedance for the resonator.

摘要： Certain aspects of the present disclosure generally relate to methods and apparatus for wirelessly charging a device having a wireless power receiver with a dead battery. One example method for safely wirelessly charging an implantable device, with an apparatus, generally includes determining that the implantable device has a dead battery; based on the determination, wirelessly transmitting power from the apparatus at an initial level for a first interval; checking for a first signal received from the implantable device during or at an end of the first interval or a period associated with the initial level; and if no first signal is received from the implantable device, increasing the transmitted power to a higher level for a second interval.

摘要： A charging system for an Implantable Medical Device (IMD) includes a split charging coil for generating a magnetic field to provide power to the IMD. The split charging coil includes a first coil portion and a second coil portion, each of which can be formed as a mechanical winding of an insulated conductor. The first and second coil portions are connected to each other in a way that substantially reduces or eliminates any current-carrying path that is routed radially with respect to the coil. As a result, the split coil produces a uniform magnetic field that enables a more accurate determination of alignment between the coil and the IMD than is available using traditional charging coils.
