Abstract: An apparatus includes a stimulation assembly having an elongate body and a plurality of stimulation elements longitudinally spaced from one another along a portion of the elongate body. The stimulation assembly includes a first set of the stimulation elements and a second set of the stimulation elements. The apparatus further includes a tube over the second set of the stimulation elements. The tube is configured to be removed from the stimulation assembly.

Abstract: An electrode assembly including a carrier section, an electrode section(s), and joint section(s). Each electrode section including an electrode contact, and an electrode section body. Each joint section connecting the carrier section to at least one electrode section, and providing each connected electrode section with at least one of pitch, roll, and yaw about a point generally along an axis between the carrier section and the electrode section. The joint section made of material of durometer less the durometer of the carrier section. A fill section can substantially occupying the space between the carrier section and the electrode section that is not occupied by the joint section.
