According to embodiments, a cerebrospinal fluid (CSF) shunt includes: an inlet configured to receive CSF from a spinal intradural space in a patient; a shunt body with a sidewall and a lumen within the sidewall, wherein the shunt body is configured to extend through an interstitial space and a vein wall, wherein the lumen is in fluid communication with the inlet; and a regulator outside of the lumen, wherein the regulator is configured to regulate a flow of the CSF from the inlet by passing a regulated portion of the CSF from the lumen and into a venous system of the patient.

Cerebrospinal fluid shunt with flow regulation

A method including: introducing a shunt into a vascular system, wherein the shunt includes an inlet aperture in an inlet region and an outlet aperture in an outlet region; positioning the inlet region into an epidural or intervertebral vein; with a stylet, puncturing a wall of the epidural or intervertebral vein, traversing an interstitial space, and puncturing a thecal sac, wherein the stylet includes a wire extending through the shunt; moving the shunt to cause the inlet region to extend through a wall of the epidural or intervertebral vein; moving the shunt to cause the inlet region to extend into an interstitial space; and moving the shunt to cause the inlet region to extend through the thecal sac, such that the inlet region is positioned in an intradural space, and such that the outlet region is positioned in a venous pathway.

Cerebrospinal fluid shunt

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.
