Abstract: A system for delivering a puncture system to puncture through a wall of a patient's blood vessel includes: a proximal catheter including a proximal lumen configured to accommodate both a primary navigation guide wire and the puncture system; a puncture system exit port in communication with the proximal lumen, wherein the puncture system exit port is configured to receive the puncture system, such that a portion of the puncture system passes through the puncture system exit port and exits the system; and a distal catheter including a distal lumen in communication with the proximal lumen, wherein the distal lumen is configured to accept the primary navigation guide wire and reject the puncture system, such that the primary navigation guide wire is able to enter the distal lumen and the puncture system is not able to enter the distal lumen.

Abstract: A shunt delivery system includes: a stylet configured to puncture a vein wall, interstitial tissue, and a dura; a dilator including a transverse hollow interior region extending to an aperture in a distal region, the dilator configured to receive the stylet in the hollow interior region and out through the aperture in the distal region, the dilator configured to pass through tissues punctured by the stylet, including the vein wall, the interstitial tissue, and the dura; and a transdural catheter including a hollow interior region configured to receive the stylet, the transdural catheter configured to traverse the tissues dilated by the dilator, including the vein wall, the interstitial tissue, and the dura, such that a distal tip of the transdural catheter is configured to be located in a thecal sac of the patient.
