Abstract:

Systems and methods for deploying a paddle neurostimulation lead within a patient. A delivery tool includes a delivery tube including a first linear segment, a second linear segment, and an arcuate segment coupled between the first and second linear segments, the second linear segment defining an elongated opening. The delivery tool further includes a stylet positioned within an interior of the delivery tube, and a handle coupled to the delivery tube and including a stylet actuation mechanism, the stylet actuation mechanism configured to selectively advance and retract the stylet between a deployed position and a retracted position, wherein the stylet extends across the elongated opening in the deployed position to engage an engagement member of the paddle neurostimulation lead.
