Abstract

A vaso-occlusive device having a delivery configuration when restrained within a delivery catheter and having a deployed configuration when released from the delivery catheter into an aneurysmal sac is provided, the device comprising a tubular structure including a distal portion configured for expanding within the aneurysmal sac when distally deployed from the delivery catheter into the aneurysmal sac, a proximal portion configured for inverting and expanding into the expanded distal portion when distally deployed from the delivery catheter, thereby creating multi-layer scaffolding within the aneurysmal sac, and an inflection region between the distal portion and the proximal portion, wherein the inflection region is configured for urging the inversion of the proximal portion into the expanded distal portion.
