Abstract
An implantable stimulation lead has electrode contacts that are configured to deliver an electrical stimulation therapy for a patient. A sheath extends along a longitudinal axis. The sheath defines a lumen into which the stimulation lead can be inserted. A distal end of the sheath includes a plurality of base segments that are separated from one another. A plurality of fixation structures are located on the base segments, respectively. In a first configuration, the fixation structures are each disposed proximate to the sheath. In a second configuration, the fixation structures each extend radially outward from the sheath. In a third configuration, the base segments deflect radially inward toward the longitudinal axis.
