Outcome

Type Measure Description Time frame Safety issue
Other Number of Participants With Reported Device Related Serious Adverse Events This secondary outcome measure provides the count of participants reported with a Serious Device Related Adverse Events From the point of consent until participant exits the study at 1 year
Primary Number of Participants With Neurologic Death or Major Ipsilateral Stroke Within 12 Month Follow-up Period. The primary safety endpoint was the number of participants reported with a neurological death or major ipsilateral stroke (National Institute of Stroke Scale (NIHSS) increase of = 4 for > 24 hours) at any time during the follow-up period.
The NIHSS is a tool used to quantify neurological impairment caused by stroke. The scale interpretation is as follows:
0: No stroke symptoms 1-4: Minor stroke symptoms 5-15: Moderate stroke 16-20: Moderate to severe stroke 21-42: Severe strokeThe National Institutes of Health Stroke Scale
12 months, after device implant
Primary Number of Participants With Raymond Grade I ( 100%) Occlusion of the Aneurysms for Participants Treated With the Barrel VRD at 12 Months in the Absence of Retreatment, Parent Artery Stenosis, or Target Aneurysm Rupture The primary effectiveness endpoint was the count of participants achieving Raymond Grade I (100% occlusion) of the aneurysm treated with the Barrel VRD at 12 months ± 8 weeks in the absence of retreatment, parent artery stenosis (>50%), or target aneurysm rupture
The Raymond Grade Classification definitions evaluated by an independent core laboratory are as follows:
Class 1: Complete occlusion - complete obliteration of the aneurysm. Class 2: Residual neck - persistence of any portion of the original defect of the arterial wall as seen on any single projection, but without opacification of the aneurysmal sac.
Class 3: Residual aneurysm - opacification of the aneurysmal sac
12 months, after device implant
Secondary Number of Participants With Successfully Deployed Barrel VRD This secondary outcome measure provides the number of subjects successfully implanted with the Barrel VRD. Index Procedure, Day 0
Secondary Number of Participants With Raymond Grade I (100% Complete Occlusion) and Raymond Grade II (Residual Neck) for Participants Treated With the Barrel VRD, in the Absence of Retreatment, Parent Artery Stenosis (>50%), or Target Aneurysm Rupture at 12 Months This secondary outcome measure provides the count of participants treated with the Barrel VRD with Independent Core Laboratory aneurysm occlusion imaging evaluations of Complete Occlusion (Raymond Grade I) and Residual Aneurysm Neck (Raymond Grade II) at 12 months combined. Subjects with evidence of parent artery stenosis, retreatment, or rupture were not considered success.
Raymond Grade Scale
Class 1: Complete occlusion - complete obliteration of the aneurysm. Class 2: Residual neck - persistence of any portion of the original defect of the arterial wall as seen on any single projection, but without opacification of the aneurysmal sac.
Class 3: Residual aneurysm - opacification of the aneurysmal sac.
12 months, after device implant
Secondary Number of Participants With Modified Rankin Score of 0-2 or no Change From Baseline This secondary outcome provides the count of participants treated with the Barrel device with a Modified Rankin Score of 0-2 at 12 months or no change from baseline.
The Modified Rankin Score is a scale for measuring general functionality as follows:
0: No symptoms at all
No significant disability despite symptoms; able to carry out all usual duties and activities
Slight disability; unable to carry out all previous activities, but able to look after own affairs without assistance
Moderate disability; requiring some help, but able to walk without assistance
Moderately severe disability; unable to walk without assistance and unable to attend to own bodily needs without assistance
Severe disability; bedridden, incontinent and requiring constant nursing care and attention
Dead
12 months, after device implant
Secondary Number of Participants With Angiographic Evidence of In-stent Stenosis at 12 Months +/- 8 Weeks Reported According to the Following Ordinal Groups: <25%, 25-50%, 51-75%, >75% This secondary measure provides the count of participants with parent artery stenosis per an independent core lab evaluation within the following ordinal groups: <25%, 25-50%, 51-75%, >75%. At 12 Months +/- 8 weeks
Secondary Number of Participants With Any Cause of Death Within 30 Days or Neurological Death Within 12 Months +/- 8 Weeks This secondary outcome measure provides the combined number and percentage of subjects that died within 30 days or had a neurologic death within 12 months of receiving the study device. 30 Days and 12 months +/- 8 weeks
