Methods and systems for treating hydrocephalus
First Claim
1. A system for treating a patent with elevated intracranial pressure, the system comprising:
- a cerebrospinal fluid shunt configured for deployment through a venous system of the patient, the shunt comprising a proximal portion, a distal portion having a distal anchoring mechanism, and a shunt lumen in fluid communication with one or more distal openings in the distal portion and one or more proximal openings in the proximal portion; and
a delivery system configured for creating an anastomosis between an inferior petrosal sinus and a C SF-filled subarachnoid space of the patient, and for deploying the shunt in the anastomosis with the distal portion of the shunt positioned in the subarachnoid space, such that, when the shunt is deployed in the anastomosis, CSF flows from the subarachnoid space through the one or more distal openings, lumen, and one or more proximal openings of the shunt, 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.
