A neurostimulation (NS) system and method are provided. The system includes a power supply having positive and negative terminals. The negative terminal defines a reference ground. An array of electrodes includes first and second active electrodes for delivering stimulation therapy configured to be located proximate to neural tissue of interest that is associated with a target region. A control circuit is configured to control delivery of stimulation current for a NS therapy between the first and second electrodes. A current regulator (CR) circuit is connected to, and configured to control current flow through, at least the first electrode during delivery of the stimulation therapy under direction of the control circuit. A floating power supply is connected across power supply terminals of the CR circuit. The CR circuit and floating power supply are coupled to a floating ground node that is electrically separate from the reference ground.

A shield located within an implantable medical lead may be terminated in various ways at a metal connector. The shield may be terminated by various joints including butt, scarf, lap, or other joints between insulation layers surrounding the lead and an insulation extension. The shield may terminate with a physical and electrical connection to a single metal connector. The shield may terminate with a physical and electrical connection by passing between an overlapping pair of inner and outer metal connectors. The metal connectors may include features such as teeth or threads that penetrate the insulation layers of the lead. The shield may terminate with a physical and electrical connection by exiting a jacket of a lead adjacent to a metal connector and lapping onto the metal connector.

The present disclosure provides systems and methods for a conductor assembly for an implantable lead cable. The conductor assembly includes a conductive element extending over an axial length from a proximal end to a distal end. The conductor assembly includes an inner dielectric layer coaxially covering the conductive element over the axial length. The conductor assembly includes an inner conductive layer coaxially covering the inner dielectric layer over the axial length, the inner conductive layer comprising a contiguous metal coating having a thickness in a range of 1 to 50 microns.

A medical lead includes a main body having a length extending from a proximal end to a distal end, a longitudinal axis parallel to the length, and a proximal portion adjacent to the proximal end and a distal portion adjacent to the distal end; a plurality of electrodes defining an electrode region; and an imaging marker positioned between the electrode region and the proximal end and separated from the electrode region by a distance in an axial direction. The imaging marker may include one or more marker segments. The imaging marker may be disposed in a pocket of a sleeve at least partially surrounding the main body and comprising one or more pockets for receiving the imaging marker. The medical lead may be operatively connected to an implantable medical device.

An implantable medical device includes at least one conductive element and an associated attenuation arrangement to attenuate MRI energy.

The present invention provides an active implantable medical device (AIMD) comprising an implantable lead, an application specific integrated circuit (ASIC) within a hermetic enclosure of the AIMD, and a sensing and cancellation wave output from the ASIC supplying to the lead. The invention also provides a method of reducing heating of an AIMD and a lead thereof.

An implantable medical device, including a magnet apparatus and a support body supporting the magnet apparatus, wherein the magnet apparatus has a long axis and a short axis shorter than the long axis normal to the long axis and at least one of the top surface or the bottom surface of the magnet apparatus establishes a curved outer periphery with respect to a cross-section lying on a plane on which the long axis lies and which is parallel to the short axis.

An implantable electrical stimulation lead includes at least three modular lead elements configured to couple together to form the lead, each of the modular lead elements including a proximal end portion, a distal end portion, and a male connector element or a female connector element disposed on at least one of the proximal end portion or the distal end portion of the modular lead element, The modular lead elements are coupleable together by insertion of a male connector element into a female connector element.

Medical lead bodies that are paired each include a braided conductive shield. The braided conductive shield of one lead body has a value for a physical parameter that differs from a value for the physical parameter of the second lead body. The difference in values of the physical parameter for the paired lead bodies results in a reduction in heating from exposure of the lead bodies to radiofrequency energy at electrodes associated with the lead bodies. The lead bodies may be paired by being implanted adjacently to one another. The lead bodies may be further paired by being coupled to a same distal body, such as a paddle containing the electrodes.
