Research Overview

James Lock's research focused on improving procedures to correct congenital heart defects in infants and children. He has developed and provided the initial descriptions of nearly a dozen new techniques in interventional cardiology

Dr. Lock was one of the inventors of the CardioSEAL® device, which is implanted through a catheter to correct certain congenital heart defects. CardioSEAL is FDA-approved under Humanitarian Use Guidelines for the treatment of ventricular septal defect, Fontan fenestration, and patent foramen ovale, and for treating atrial septal defect in clinical trials. STARflex, a second-generation device, is being tested in clinical trials for the same indications.
