Methods and systems for treating hydrocephalus
First Claim
1. A shunt configured for being deployed in an inferior petrosal sinus (IPS) of a patient, the shunt comprising:
- a distal portion configured for being introduced into, and secured within, a cerebellopontine (CP) angle cistern of the patient via the IPS, the CP angle cistern containing cerebrospinal fluid (CSF); and
a main body portion configured for being disposed within the IPS, the main body portion including a shunt lumen, wherein the shunt lumen is in fluid communication with one or more CSF intake openings located in the distal portion; and
a CSF outflow opening in fluid communication with the shunt lumen,such that, when the shunt is deployed in the IPS with the distal portion of the shunt disposed within the CP angle cistern and the main body portion of the shunt disposed within the IPS, CSF flows from the CP angle cistern through the one or more CSF intake openings, shunt lumen, and CSF outflow opening, respectively, into the venous system of the patient.

Abstract
Methods for treating hydrocephalus using a shunt, the shunt having one or more CSF intake openings in a distal portion, a valve disposed in a proximal portion of the shunt, and a lumen extending between the one or more CSF intake openings and the valve, the method comprises deploying the shunt in a body of a patient so that the distal portion of the shunt is at least partially disposed within a CP angle cistern, a body of the shunt is at least partially disposed within an IPS of the patient, and the proximal portion of the shunt is at least partially disposed within or proximate to a JV of the patient, wherein, after deployment of the shunt, CSF flows from the CP angle cistern to the JV via the shunt lumen at a flow rate in a range of 5 ml per hour to 15 ml per hour.

8. A method for treating hydrocephalus, including normal pressure hydrocephalus, and/or elevated intracranial pressure, the method comprising:
-
positioning a shunt so that a distal end portion of the shunt is deployed in a cerebellopontine (CP) angle cistern of a patient, and a body of the shunt is at least partially positioned in an inferior petrosal sinus (IPS) of the patient, the CP angle cistern containing cerebrospinal fluid (CSF), the distal end portion of the shunt comprising one or more CSF fluid intake openings, the shunt comprising a CSF outflow opening, and the body of the shunt comprising a shunt lumen in fluid communication with the one or more CSF fluid intake openings and with the CSF outflow opening, such that CSF flows from the CP angle cistern through the one or more CSF intake openings, shunt lumen, and CSF outflow opening, respectively, into the venous system of the patient. - View Dependent Claims (9, 10, 11)
