Abstract
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.

A cerebrospinal fluid (CSF) shunt, comprising:
- 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 at least partially 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.
A cerebrospinal fluid (CSF) shunt, comprising:
- an inlet configured to receive CSF from a spinal intradural space in a patient;
- an outlet configured to provide the CSF into a venous system in the 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 the outlet, such that a flow of the CSF flows between the inlet and the outlet;
- and
- a regulator configured to vary at least one of a size or a shape of the outlet to regulate the flow of the CSF.
