A custom length stylet assembly for meeting medical device length tolerances. The custom length stylet assembly including a stylet wire having a length extending between a distal end and a proximal end, stylet handle defining a longitudinally oriented throughbore sized to retain a proximal portion of the stylet wire, the stylet handle further defining a proximately positioned track and tab, the track configured to retain a bent proximal end portion of the stylet wire, the length of the stylet wire selected during assembly of the stylet assembly to conform to the corresponding length of a body implantable lead within a predefined tolerance, the tab of the stylet handle melted into the track, thereby securely fastening stylet wire to the stylet handle to inhibit rotation or dislodgement.

Custom length stylet

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

An implantable medical electrical lead includes an electrode assembly in which an electrical junction between a first conductor and an inner surface of a first electrode of the assembly is wedged within a first channel of at least one core member of the assembly, around which the first electrode extends. The at least one core member is formed from an insulating material, and the first channel may be one of a plurality of longitudinally extending channels arrayed around a circumference of a central lumen of the assembly, which is defined by the at least one core member. The first conductor extends along a length of the assembly, for example, defined between the first electrode and a second electrode thereof, in a helical path that travels around the central lumen.

Electrode assemblies, methods, and components thereof for implantable medical electrical leads

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.

Medical lead with segmented electrodes

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.
