Abrégé
Implantable medical devices (IMD) such as those used in Deep Brain Stimulation application are commonly replaced when the device's useful life expires. At the time of replacement, the electrodes that were connected to the initial IMD are typically reused with the replacement IMD. It is desirable for the replacement IMD to utilize the stimulation parameters that were being utilized to provide stimulation in the initial IMD, but it is important that the electrodes be connected to the replacement IMD in a similar manner as they were connected to the initial IMD if stimulation parameters are reused. A connected electrode profile that includes measurements of electrical parameters associated with the electrodes can be generated in the initial IMD and the replacement IMD, and the profiles can be compared to determine whether the electrodes are connected in a similar manner in the replacement IMD as they were in the initial IMD.

Abrégé
A charging system for an Implantable Medical Device (IMD) is disclosed having a charging coil and one or more sense coils preferably housed in a charging coil assembly coupled to an electronics module by a cable. The charging coil is preferably a wire winding, while the sense coils are preferably formed in one or more traces of a circuit board. One or more voltages induced on the one or more sense coils can be used to determine one or more parameters (magnitude, phase angle, resonant frequency) indicative of the position between the charging coil and the IMD, which position may include the radial offset and possibly also the depth of the charging coil relative to the IMD. Knowing the position, the power of the magnetic field produced by the charging coil can be adjusted to compensate for the position.

Pairing of External Communication Devices With an Implantable Medical Device via a Patient Remote Controller
Boston Scientific Neuromodulation Corporation (USA)
Inventeur(s)
Shah, Chirag
Yoo, Peter
Abrégé
Techniques for pairing an external device such as a clinician programmer (CP) to an implantable medical device (IMD) are disclosed, which involve use of a remote controller (RC) paired to the IMD. The RC is placed into a CP pairing mode, which acts differently depending on the type of IMD paired to the RC. If the IMD is RF based, the CP pairing mode places the IMD in a pairing mode, thus allowing the CP to connect directly with the IMD via a RF telemetry protocol. If the IMD is magnetic-induction based, the CP pairing mode causes the RC to advertise its presence to the CP, allowing the CP to connect to the RC via the RF telemetry protocol. Because the RC is also paired with the IMD via a magnetic induction telemetry protocol, the RC acts as a passthrough device to allow communications between the CP and the IMD.

Abrégé
Recovery circuitry for passively recovering charge from capacitances at electrodes in an Implantable Pulse Generator (IPG) is disclosed. The passive recovery circuitry includes passive recovery switches intervening between each electrode node and a common reference voltage, and each switch is in series with a variable resistance that may be selected based on differing use models of the IPG. The passive recovery switches may also be controlled in different modes. For example, in a first mode, the only recovery switches closed after a stimulation pulse are those associated with electrodes used to provide stimulation. In a second mode, all recovery switches are closed after a stimulation pulse, regardless of the electrodes used to provide stimulation. In a third mode, all recovery switches are closed continuously, which can provide protection when the IPG is in certain environments (e.g., MRI), and which can also be used during stimulation therapy itself.
