Abstract

The present disclosure relates to implantable stimulators, and more particularly relates to implantable deep brain stimulators and methods utilizing one or more stimulators to treat various neurological conditions. The deep brain stimulating device of the present disclosure eliminates the need to have a connector. It uses a magnetic material on the stimulating electrode assembly to respond to the stimulating frequencies and allows the stimulator to be located external to the patient’s head.

Deep Brain Connectorless Fully Implantable Stimulator and Method of Using

Background

                    The present disclosure relates to implantable stimulators, and more particularly relates to implantable deep brain stimulators and methods utilizing one or more stimulators to treat various neurological conditions.  The deep brain stimulating device of the present disclosure eliminates the need to have a connector.  It uses a magnetic material on the stimulating electrode assembly to respond to the stimulating frequencies and allows the stimulator to be located external to the patient’s head.

                    The term “lead,” as used herein, will refer to an elongate conductor covered by insulation and which conductor is connected to an electrode contact.  An “electrode contact” is a conductive material that is exposed to the tissue to be stimulated.  An “electrode”, on the other hand, generally refers to that part of the lead that includes the electrode contact as well as a portion of insulation or other lead structure near the electrode contact.  The term “electrode” may be used, herein, interchangeably with a stimulating lead.  A stimulation lead may be made from one or more conductive wires.  At the distal end of the lead, the conductor wire can be connected to one or more electrode contacts.  In prior art applications, the conductor coil is usually connected to an electrical connector, which connector is usually connected to a lead extension, which lead extension can be connected to a pulse generator.  As will be apparent from the description provided herewith, the need for an electrical connector or lead extension is eliminated.  In the instance where a trial stimulator is required during the surgery procedure, the trail stimulator can communicate with the implantable DBS system through the same inductive coupling components enclosed within the implantable DBS system of the present disclosure.  Finally, the electrode contacts on the distal end of the lead interface with brain tissue and can deliver a stimulating current to cause the brain tissue to be stimulated.

                    Deep Brain Stimulation is a well know medical treatment used for applying electrical stimulation to one or more areas of the brain for treating or preventing obesity and/or other eating disorders, as well as the symptoms and pathological consequences thereof.  Proper stimulation of specific sites in the brain via Deep Brain Stimulation (DBS) may lead to changes in levels or responses to neurotransmitters, hormones, and/or other substances in the body that treat eating disorders.

                    Deep Brain Stimulation (DBS) has also been applied to the treatment of central pain syndromes.  DBS is currently being explored as a therapy for epilepsy, for treatment of mood and/or anxiety disorders as a therapy for depression, for treating or preventing diabetes, for the treatment of movement disorders such as e...
