Publication number: 20230233819Abstract: An intracranial intervention system comprises a seeker wire and delivery catheter used to navigate and access a target location within the intracranial subarachnoid spaces (ISAS) of a patient. A microcatheter is then advanced through the delivery catheter to perform a therapeutic procedure, such as installing a shunt within the ISAS to drain cerebral-spinal fluid (CSF). The shunt may be configured to drain CSF from a first and second ISAS, and includes a distal portion which extends into the first ISAS via the second ISAS and a dural venus sinus (DVS) of the patient. The shunt has a main body portion positioned and secured within the second ISAS, a distal portion extending into the first ISAS and the main body portion in the second ISAS have CSF intake opening which allow CSF to flow into a shunt lumen and out through an outflow opening positioned in the DVS.Type: ApplicationFiled: March 27, 2023Publication date: July 27, 2023Applicant: CEREVASC, INC.Inventors: Adel M.
