An electrical stimulation lead includes a lead body insertable into a patient. Electrodes are disposed along the lead body. The electrodes include at least two sets of segmented electrodes. Each set of segmented electrodes includes a first segmented electrode and a second segmented electrode radially spaced apart from one another around a circumference of the lead body. A tab is disposed on the first segmented electrode of each set of segmented electrodes. The tabs extend into the lead body. A guide feature is disposed on the tabs. The guide features are each radially aligned with one another along the length of the lead body. Conductors extend along the length of the lead body from a proximal end to the electrodes. Each of the conductors is electrically coupled to at least one of the electrodes. At least one of the conductors extends through the radially-aligned guide features of the tabs.

An implantable paddle lead includes at least one lead body with a proximal end and a distal end. Terminals are disposed at the proximal end of the lead body. A paddle body is coupled to the distal end of the lead body. The paddle body has a length, a width, a first surface, and an opposing second surface. Electrodes are disposed on the first surface of the paddle body. At least one region of the paddle body has a higher pliability than remaining portions of the paddle body. The at least one region of higher pliability extends along the second surface of the paddle body. The paddle body is configured and arranged to preferentially bend along the at least one region of higher pliability. Conductors are disposed along the paddle lead. Each conductor electrically couples at least one of the electrodes to at least one of the terminals.

A lead assembly for an electrical stimulation system includes a lead scaffold that defines first, second, and third channels defined along the first major surface of the lead scaffold. The first, second, and third channels are parallel to one another and to a longitudinal length of the lead scaffold. A tapered guide feature is coupled to one end of the lead scaffold. The lead assembly also includes first and second leads with electrodes at distal ends of the leads, terminals at proximal ends of the leads, and conductive wires coupling the electrodes to the terminals. The first lead is insertable into the first channel and the second lead is insertable into the second channel.
摘要:
A lead includes a lead body defining a lumen extending through the lead body; a conductor disposed in the lumen; a slit extending from an exterior of the lead body through at least a portion of the lead body to the lumen; and a contact strip. A portion of the contact strip is optionally disposed in the slit and is in contact with a portion of the conductor. A second portion of the contact strip is optionally wrapped around the lead body. A method of making a lead includes disposing one or more conductors in a lumen of a lead body; forming a slit from an exterior of the lead body to the lumen to access a portion of at least one conductor disposed in the lumen; coupling a flat contact strip to the portion of the conductor, and wrapping the contact strip around the lead body.
