Permanent transcatheter closure of atrial septal defects

GORE® HELEX® Septal Occluder

Open heart surgery is no longer the only available option to correct atrial septal defects in young children and in patients with complicating health factors. Today's health care providers are seeking safe and effective non-surgical options to close inter-atrial defects.

The GORE® HELEX® Septal Occluder is a permanently implanted prosthesis and catheter delivery system indicated for the transcatheter closure of ostium secundum atrial septal defects (ASDs). The pre-assembled delivery system allows easy deployment of the device via standard femoral venous access.

The Occluder, which is composed of ePTFE patch material supported by a single nitinol wire frame, bridges and eventually occludes the septal defect to stop the shunting of blood between the atria. Over the course of several weeks to months, cells begin to infiltrate and grow over the ePTFE membrane, ensuring successful closure of the defect.
