A method for programming a deep brain stimulator implanted in a target region of a brain of a living subject. In one embodiment, the method comprises the steps of creating an efficacy atlas; acquiring a position of each electrode contact of the at least one electrode; mapping the acquired position of each electrode contact of the at least one electrode onto a corresponding position in the efficacy atlas so as to determine the efficacy of stimulation at the acquired position; and selecting one or more electrode contacts having the highest efficacy for stimulation.

The present invention discloses an implantable pulse generator (IPG) operable as a deep brain stimulator (DBS) which is mountable to the skull of a DBS patient, and which therefore is much closer to the site of intended therapy. The IPG includes an electronics section, a charging coil section, a connector block section configured to connect to the proximal end of implanted leads, and an electrodewire section connecting the connector block section to the electronics section. The electronic section includes a housing that is position able into a hole formed in the patient's skull. Once so positioned, the housing may be affixed to the skull via bone screws. The charging coil section may be separate from and non-overlapping with the electronics section, or the charging coil section may encircle the electronics section.

An implant for deep brain stimulation (DBS) has an array of electromagnetic microcoils dispersed over the length of the implant. The microcoils produce magnetic fields that are directed into, and induce current in, the adjacent brain tissue. The microcoils may be selectively operated to direct and focus electrical stimulation to targeted areas of the brain. The implant is useful in studying or treating neurophysiological conditions associated with the deep regions of the brain such as Parkinson's disease, drug addiction, and depression.

The present invention consists of an implantable device with at least one package that houses electronics that sends and receives data or signals, and optionally power, from an external system through at least one coil attached to at least one package and processes the data, including recordings of neural activity, and delivers electrical pulses to neural tissue through at least one array of multiple electrodes that are attached to the at least one package. The device is adapted to electrocorticographic (ECoG) and local field potential (LFP) signals. A brain stimulator, preferably a deep brain stimulator, stimulates the brain in response to neural recordings in a closed feedback loop. The device is advantageous in providing neuromodulation therapies for neurological disorders such as chronic pain, post traumatic stress disorder (PTSD), major depression, or similar disorders. The invention and components thereof are intended to be installed in the head, or on or in the cranium or on the dura, or on or in the brain.

Due to the lack of internal anatomic detail with traditional magnetic resonance imaging, preoperative stereotactic planning for the treatment of tremor usually relies on indirect targeting based on atlas-derived coordinates. To overcome such disadvantages, a method is provided that allows for deep brain stimulation targeting based on brain connectivity. For example, probabilistic tractography-based thalamic segmentation for deep brain stimulator (DBS) targeting is suitable for the treatment of tremor.

The invention discloses a percutaneous closed-loop control charging device for implantation type medical treatment instrument and belongs to the technical field of implantation medical instrument. The percutaneous closed-loop control charging device for implantation type medical treatment instrument comprises an external charger and an internal implantation type medical instrument. An external energy transmitting coil is a large-size flat magnetic core coil, and an internal energy receiving coil is a hollow coil; the external energy transmitting coil transmits electromagnetic energy by adopting a resonance electromagnetic coupling manner with parallel central shafts; and the electrical energy obtained by the internal energy receiving coil charges an internal rechargeable battery through an internal charge control circuit. The closed-loop control charging device communicates in a pulse position modulation manner for closed-loop control to ensure the energy received by the implantation medical instrument in different charging phases to be within the normal range, effectively control the heating and increase the safety; the closed-loop control charging device calculates the efficiency by the internal feedback parameter to realize counterpoint prompt and increase the charging efficiency. The percutaneous wireless charging method can charge the implantation type medical instrument by a titanium casing, is safe and reliable in charging, and can be applied to all types of implantation type medical instruments equivalent to a deep brain stimulator in power level.

A device, method and means to adjust the position of a picafina Deep Brain Stimulator (DBS). It is notoriously difficult to find the correct positioning of the picafina for best stimulating results, because it is not possible for the neurosurgeon to visually observe its position. We disclose a device, method and means to adjust the position of the picafina after it is inserted in the brain, for the best stimulating effect.

According to the invention methods and structures for determining whether impingement of x-ray radiation upon potentially vulnerable discrete components, circuits and / or circuit pathways of an implantable medical device (IMD) causes modifications or damage thereto. The invention includes structures for deflecting impingement of x-ray radiation from said potentially vulnerable components, circuits and / or circuit pathways. The x-ray radiation can be generated by various imaging modalities or unknown sources. Myriad IMDs can utilize the teaching of the present invention, including for example, a pacemaker, a drug delivery pump, a nerve stimulation device, a muscle stimulation device, an implantable cardioverter-defibrillator, a subcutaneous defibrillator, a deep brain stimulator or the like.
