Using direct fluoroscopic control and commercially available microcatheters, the device was introduced into the aneurysms. At 2\u2005months, 12\u2005months and 24\u2005months, follow-up angiography was performed and analyzed.

The open pores permitted fibrous tissue ingrowth. By 2\u2005months, all of the aneurysm necks had been covered by fibrous tissue and a neointima. Two of the aneurysms originally inadequately filled allowed opportunity for retreatment. The reactive change within the aneurysms demonstrated fibroblastic proliferation, collagen and some giant cells but no vascular necrosis.
