Use of occluder devices for a patent ductus arteriosus (PDA) closure is restricted to small diameter PDAs and involves high device costs. The objective of this study was to develop a new nitinol implant for the closure of a PDA and to evaluate its safety and efficacy in an animal model. The design c...
