Abstract
An occlusion device having laminated polyvinyl alcohol sheets for occluding a defect. The laminated polyvinyl alcohol sheets provide an increased tear strength to the sheets that allows the device to be fully retrievable through the same catheter used to deploy it. The laminated sheets are created by obtaining thin sheets of polyvinyl alcohol foam, arranging the sheets on one another, and applying heat and pressure to laminate the sheets together.
