The duct-occlud device: design, clinical results, and future directions.
The successful employment of embolization coils for transcatheter occlusion of the patent ductus arteriosus (PDA) has resulted in acceptance of transcatheter occlusion as the treatment of choice for small to medium-sized PDAs. The Duct-Occlud device was developed to further improve the technique by utilizing a controlled release mechanism and coil shape specifically designed for the geometry of the ductus arteriosus. Clinical studies have demonstrated excellent efficacy with low embolization rates and low incidences of complications. Newer modifications have been designed for occlusion of larger PDAs and subaortic ventricular septal defects, and preliminary clinical results have been promising.
