AGA Medical Features AMPLATZER Muscular VSD Occluder for Ventricular Septal Defect Closure
At TCT 2008 AGA Medical Corp. highlighted its self-expanding AMPLATZER Muscular VSD Occluder for complex ventricular septal defect (VSD) repair in patients considered to be high-risk for standard transatrial or transarterial surgical repair.
AGA Medical designed the AMPLATZER Muscular VSD Occluder to allow closure of muscular ventricular defects using a minimally-invasive catheter procedure instead of surgery.
The Muscular VSD Occluder has two concentric discs and a long waist to accommodate the thicker portion of the ventricular septum. Polyester fabric inserts help close the hole and provide a foundation for growth of tissue over the occluder after placement. The physician deploys the occluder to expand each disc on either side of the defect, closing off the hole.
