A medical lead system includes a lead body, a plurality of electrical conductors, and a plurality of electrodes. The lead body may include a distal end and a proximal end defining a longitudinal axis of the lead body. The plurality of electrical conductors extending about the longitudinal axis of the lead body. The plurality of electrodes is positioned around an outer perimeter of the lead body. An inner surface of each of the plurality of electrodes defines an inner perimeter. Each respective electrode of the plurality of electrodes is electrically coupled to a respective electrical conductor of the plurality of electrical conductors. Each electrode of the plurality of electrodes includes at least one electrode locking feature extending into the lead body from the inner perimeter.

A neuromodulation adaptor configured to provide an electrical coupling between an otherwise incompatible stimulation lead and neurostimulator device, the neuromodulation adaptor including a proximal portion having a plurality of electrical conductors spaced apart at a first pitch spacing and configured to electrically engage with a corresponding plurality of electrical terminals of a neurostimulator device, and a distal portion including a stimulation lead port assembly, the stimulation lead port assembly including an upper portion and a lower portion configured to house the plurality of conductor elements and a set screw assembly, the plurality of conductor elements and set screw assembly spaced apart at a second pitch spacing and configured to electrically engage with a corresponding plurality of electrical connectors of a stimulation lead.

Electrically isolated connector for implantable medical devices

Various embodiments of this disclosure concern a lead end containing a slotted member. A slotted member can have a plurality of slots extending along at least a portion of the length of the slotted member, each of the slots having a respective positioning feature, the plurality of slots having a plurality of positioning features at different longitudinal positions along the length of the slotted member. The lead end can further include a plurality of conductors at least partially within the plurality of slots, each slot of the plurality of slots containing at least a respective one of the plurality of conductors, the plurality of conductors electrically connecting exposed electrical elements of both ends of the lead.

Lead end having slotted member

An assembly for forming a medical lead includes a lead body, a plurality of electrical conductors extending about a longitudinal axis of the lead body, and at least one segmented electrode preform that includes an electrically conductive ring and an insulator portion within the electrically conductive ring. The electrically conductive ring includes a plurality of electrode portions and a plurality of raised portions that alternate continuously around the ring. Each of the plurality of electrode portions is continuous at a radius from a center of the electrically conductive ring that corresponds to an outer perimeter of the medical lead. The insulator portion has a plurality of projections each extending into a respective raised portion of the ring beyond a radius that corresponds to the outer perimeter of the medical lead. Each respective electrode portion is electrically coupled to a respective electrical conductor of the plurality of electrical conductors.

Pre-molded cylindrical sub-assemblies for inclusion in an implantable medical lead are described. The pre-molded cylindrical sub-assemblies comprise a cylindrical conductive element formed from a conductive material to define a substantially continuous interior surface and a substantially continuous exterior surface, and an insulative element formed from an insulative material molded onto the interior surface of the cylindrical conductive element. An interior surface of the insulative element defines a lumen of the pre-molded cylindrical sub-assembly configured to receive one or more elongated conductors of the implantable medical lead, and the cylindrical conductive element is configured to be electrically connected to one of the elongated conductors with the elongated conductors within the lumen. The cylindrical conductive element may act as an electrode, e.g., on a distal portion of the lead, or a connector, e.g., on a proximal portion of the lead.
