ATLAS IDE Study Results

Treat anterior and posterior aneurysms with confidence

The ATLAS IDE study has shown excellent results from the largest pivotal data with high complete occlusion and low complication rates.

Atlas IDE Study

The ATLAS anterior and posterior IDE Study is the largest of its kind, with 298 patients having diverse anatomical locations.

Primary efficacy endpoint 84.7% 76.7%
Primary safety endpoint 4.4% 4.3%
Retreatment rate 3.8% 7.8%

"With the additional challenges that come with treating posterior circulation aneurysms, we never would have anticipated reaching occlusion rates that rival those found in the anterior circulation. Now with Neuroform Atlas, those same high rates are achievable."

Dr. Brian Jankowitz

1. Primary efficacy endpoint complete aneurysm occlusion (Raymond-Roy class 1) on 12-month angiography, in the absence of retreatment or parent artery stenosis (>50%) at the target location.

2. Primary safety endpoint of any major ipsilateral stroke or neurological death within 12 months.

3. Retreatment rate.
