Cerebrospinal Fluid Shunt

A cerebrospinal fluid shunt for placement in a patient, the cerebrospinal fluid shunt comprising:

• an inlet region configured to pass through an aperture in an epidural vein wall or an intervertebral vein wall, to pass through an aperture in a thecal sac, and to pass through an interstitial space between one of the epidural vein wall or the intervertebral vein wall and the thecal sac;
• an inlet aperture in the inlet region, wherein the inlet aperture is configured to receive cerebrospinal fluid from an intradural space;
• an outlet region configured to be positioned in a venous pathway;
• an outlet aperture in the outlet region, wherein the outlet aperture is in fluid communication with the inlet aperture, wherein the outlet aperture is configured to permit flow the cerebrospinal fluid received by the inlet aperture out of the cerebrospinal fluid shunt;
• a transverse region between the inlet region and the outlet region, wherein the transverse region comprises a channel to enable fluid communication between the inlet aperture and the outlet aperture;
• and
• a regulator configured to partially decrease a flow of the cerebrospinal fluid through the channel.

A system, comprising:

• a cerebrospinal fluid shunt for placement in a patient, the cerebrospinal fluid shunt including:
• an inlet region configured to pass through an aperture in an epidural vein wall or an intervertebral vein wall, to pass through an aperture in a thecal sac, and to pass through an interstitial space between one of the epidural vein wall or the intervertebral vein wall and the thecal sac;
• an inlet aperture in the inlet region, wherein the inlet aperture is configured to receive cerebrospinal fluid from an intradural space;
• an outlet region configured to be positioned in a venous pathway;
• an outlet aperture in the outlet region, wherein the outlet aperture is in fluid communication with the inlet aperture, wherein the outlet aperture is configured to permit flow the cerebrospinal fluid received by the inlet aperture out of the cerebrospinal fluid shunt;
• and
• a transverse region between the inlet region and the outlet region, wherein the transverse region comprises a channel to enable fluid communication between the inlet aperture and the outlet aperture;
• and
• a hollow tube including a region configured to engage the cerebrospinal fluid shunt, wherein the hollow tube is configured to be moved and to responsively move the cerebrospinal fluid shunt.
