Atrial septal closure occlusion device HELEX®

The GORE® HELEX® Septal Occluder, which is pre-assembled and composed of ePTFE patch material, is a permanently implanted prosthesis and catheter delivery system indicated for the transcatheter closure of ostium secundum atrial septal defects (ASDs). It's delivery system allows easy deployment of the device via standard femoral venous access. It is a safe and effective non-surgical options for the providers to close inter-atrial defects instead of an Open heart surgery to correct atrial septal defects in young children and in patients with complicating health factors. A single nitinol wire frame supports the Occluder, which bridges and eventually occludes the septal defect to stop the shunting of blood between the atria. Eventually, the cells begin to infiltrate and grow over the ePTFE membranes over the course of several weeks to months and closes the defect successfully.
