While endoluminal [[flow diverter]]s function from within the [[parent artery]] by providing a [[scaffold]]
for [[endothelial cell]] growth at the [[aneurysm neck]] and induction of intra-aneurysmal [[thrombosis]]

[[endosaccular device]]s mimic the endoluminal devices but within the aneurysmal sac itself.

Several endosaccular flow disruptors have been developed, including the [[Woven EndoBridge]] (WEB; Microvention, Aliso Viejo, California), which was introduced in Europe in [[2011]], and [[Medina]] (Medtronic, Dublin, Ireland), Artisse (formerly LUNA; Medtronic)
