A Study to Evaluate Endoscope-assisted, Minimally-invasive Cortical Access System (MICAS) for Chronic Subdural Evacuation
A Study to Evaluate Endoscope-assisted, Minimally-invasive Cortical Access System (MICAS) for Chronic Subdural Evacuation
The purpose of this study is to evaluate a less-invasive alternative to the currently
 available method of removing aging blood in the subdural space.
Inclusion Criteria:

 -  Must be 55 years of age or greater.

 -  Have a clinically symptomatic chronic subdural hematoma greater than 1 cm in maximal
 thickness and be judged clinically to need subdural evacuation.

 Exclusion Criteria:

 -  Failure to obtain consent.

 -  Vulnerable study population.

 -  Any need for chronic anticoagulation.

 -  Pregnancy (verified by pregnancy testing at screening or medical history of a
 hysterectomy, oophorectomy, or post-menopausal).Prior surgery for subdural hematoma.

 -  Glasgow Coma Scale (GCS) less than 8.
