Abstract
Various aspects describe a lead delivery system for percutaneous introduction of a lead to a stimulation site near a neural target, such as the vagus nerve for nerve stimulation. The lead delivery system may include a needle assembly having a needle adapted to cut through tissue and provide initial access into the carotid sheath. The needle may be retracted into the lead delivery system to prevent cutting structures in the carotid sheath. The lead delivery system may also include a dilator assembly having one or more dilators to dilate a path to the stimulation site. The lead delivery system may further comprise a dilator assembly including a retractable needle adapted to cut through tissue. One or more locating elements, alternatively or in addition to one or more imaging elements, may be used on individual components of the lead delivery system for enhanced trackability and locatability within the body.
