For example, a surgical tool includes a shaft defining a proximal end, a distal end, and a longitudinal axis, a handle coupled to the proximal end of the shaft, and one or more blades configured to move between a retracted configuration and a deployed configuration, wherein the one or more blades extend, in the deployed configuration, substantially perpendicular to the longitudinal axis at the distal end of the shaft. The one or more blades may be configured to separate tissue in the deployed configuration.

Abstract: In an example, the disclosure describes a system with a lead having a proximal end and a distal end and an elongated lead body. The lead has one or more electrodes. A fixation member is located on the elongated lead body and is configured to secure the lead to tissue within a patient. The fixation member is located on the lead so the fixation member is closer to the proximal end than the one or more electrodes of the lead. A trialing adaptor receives the proximal end of the lead and is removable when a trialing period is completed. A sheath encloses at least a portion of the lead and covers the fixation member. The sheath is configured to remain in place over the lead during the trialing period.
