Detailed Description
This will be a prospective, observational, single site, first-in-man study of the SENSE device in up to 10 study subjects with primary spontaneous ICH. The treating clinicians will be blinded to the data collection and SENSE device scanning as described below.
All eligible subjects must have the diagnostic head CT scan (CT) demonstrating hemorrhage performed within 6 hours of symptom onset. While ICH and TBI patients may be evaluated in future studies, this early feasibility study is limited to primary spontaneous ICH patients only, given the relative homogeneity of this population compared with the TBI population.
Eligible subjects or legally authorized representatives will be approached for enrollment. After obtaining informed consent to participate in the study, a baseline study head CT will be performed to establish the hemorrhage volume; and the SENSE device will be placed on the subject within 15 minutes of this CT, or as soon as practicable, for initiation of monitoring. This repeat CT (after the diagnostic CT) is necessary since hemorrhage expansion (HE) occurs early in the clinical course, and the hemorrhage volume may have changed between the diagnostic CT and placement of the SENSE monitor.
After enrollment, routine clinical management will ensue in the emergency department (ED), hospital ward or intensive care unit (ICU) as appropriate. A standard of care head CT to evaluate for HE will be performed at 12 (±6) hours after the baseline study head CT. Finally, a study head CT will be performed at 72 (±12) hours to evaluate cerebral edema. Any head CT performed for clinical deterioration as standard of care between the baseline and 72 hour study CTs will also be collected and analyzed.
The SENSE device will be placed on the subject's head, and two small ink dots will be marked on the head corresponding to a known location on the device to allow for the device to be removed and replaced consistently throughout testing. The SENSE device will be set to scan every 10 minutes until the device is removed after completion of the SENSE measurement corresponding to the 72 hour CT scan. If the SENSE device is removed to perform the CT or SENSE monitoring is temporarily suspended, the SENSE device will be replaced; and SENSE monitoring will resume within 15 minutes, or as soon as practicable, after each CT scan. A SENSE measurement obtained within 15 minutes of each CT scan, or as soon as practicable thereafter, will be used for comparison with data analysis.

Genders Eligible for Study
Description
Inclusion Criteria:
- Male or female patients age 22 years and older
- Diagnostic head CT scan within 24 hours of primary spontaneous ICH symptom onset
- ICH >3mL and <90mL, as measured by the ABC method
- Signed written informed consent by study subject or, if subject is unable, by subject's next of kin or legal guardian
- Willingness and ability to comply with schedule for study procedures
Exclusion Criteria:
- Female patients who are pregnant or lactating
- Patients with any history of seizure or seizure at stroke onset
- Presence or history of any other condition or finding that, in the investigator's opinion, makes the patient unsuitable as a candidate for the SENSE device monitoring or study participation or may confound the outcome of the study
- Any intraventricular hemorrhage on the diagnostic (pre-enrollment) CT with planned placement of an intraventricular catheter
- Secondary cause of ICH suspected (e.g., arteriovenous malformation, cavernoma, aneurysm, hemorrhagic transformation ischemic stroke, venous sinus thrombosis, trauma)
- Planned withdrawal of care within 24 hours of enrollment
- Planned surgical evacuation within 24 hours of enrollment
- Current participation in a medical or surgical interventional clinical trial
- Presence of subdural, epidural or aneurysmal subarachnoid hemorrhage on diagnostic scan
- Planned continued use or prescribed use during the study of medications that, in the investigator's best clinical judgment, are known or suspected to lower the seizure threshold
- Planned continued use of medications that, in the investigator's best clinical judgment, could increase the chances for subsequent uncontrolled hemorrhage
- Planned or current use of continuous EEG monitoring

Experimental: SENSE Device Monitoring in ICH Patients
The SENSE device transmits a low power tailored electro-magnetic (EM) pulse in the radio-frequency range across the patient's brain and detects changes in the signal that may indicate intracranial hemorrhage. The device consists of two parts:
For this study, the research personnel will place the headset over the subject's head. The headset will be sized to fit snuggly. Each headset is marked with a unique headset identification number. The patient-contacting components of the molded plastic form are made from a medical grade (USP Class VI), biocompatible plastic and foam. |

The SENSE device continuously monitored patients for hemorrhage expansion (HE) defined as a greater than 3 ml increase in ICH volume.
ICH volumes were determined from the CT scans by a neuroradiologist.
The concordance of SENSE determination of HE or NHE with the CT results was determined.
