Abstract: A subcutaneous tunneling tool comprises an elongated shaft that may be inserted through an incision in a patient to create a subcutaneous tunnel under the patient's skin. The subcutaneous tunneling tool also comprises a guide mechanism secured to a proximal end of the elongated shaft, wherein the guide mechanism is configured to project a light beam aligned with the elongated shaft toward the elongated shaft. When at least a distal end of the elongated shaft is positioned beneath a patient's skin, the light beam is projected onto an external surface of the patient's skin, aligned with the elongated shaft such that the light beam may be used to guide the elongated shaft along a desired tunnel path.

Abstract: A catheter guide device configured to facilitate precise placement of a downstream end of a catheter within a patient. The catheter guide device comprises a torque assembly configured to frictionally engage an exterior surface of a catheter and a hub configured to engage a catheter sheath and thereby prevent rotation of the catheter sheath relative to the hub. The torque assembly is rotatably secured to the hub such that rotating the torque assembly relative to the hub rotates the catheter relative to the catheter sheath and thereby moves the downstream end of the catheter within the patient. The hub additionally comprises a detent mechanism configured to engage a plurality of gear teeth on an exterior surface of the torque assembly to thereby impede unintended rotation of the torque assembly relative to the hub.
