Intrasacular Aneurysm Occlusion Device with a Flexible Net or Mesh and Polymer Longitudinal Embolic Members

摘要

This invention is an intrasaccular aneurysm occlusion device with a flexible net or mesh which is deployed into an aneurysm sac and then expanded by the insertion of polymer longitudinal embolic members (e.g. polymer tubular strands) into the net or mesh. As the net or mesh expands, it comes into contact with the walls of the aneurysm sac and conforms to the shape of even an irregularly-shaped aneurysm sac.
