Brief Summary:
The objective of this feasibility study is to demonstrate the safety and feasibility of using an investigational extracorporeal system and catheter to filter hemorrhagic cerebrospinal fluid (CSF) post subarachnoid hemorrhage (SAH) treatment, and reintroduce the CSF via the same catheter.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 15 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Basic Science
Official Title: Extracorporeal Filtration of Subarachnoid Hemorrhage Via Spinal Catheter
Actual Study Start Date : March 23, 2017
Estimated Primary Completion Date : November 2018
Estimated Study Completion Date : January 2019
