Abstract
A system for intracranial access that includes a support assembly is described. The system includes a tubular probe shaft that may be advanced through a hole in the patient's skull. The tubular probe shaft houses a rotating element that cuts clot, and is connected to a vacuum source to aspirate clot fragments and blood from the site. The rotating element may have a bident shape.
