Catheters, Cardiac, Occluder Delivery
Definition : Cardiac catheters designed for insertion of occluders (e.g., umbrella, double umbrella, buttons) to close atrial and ventricular septal defects (ASD and VSD, respectively) as well as patent ductus arteriosus (PDA). These catheters usually consist of a plastic tube with a lumen, typically 7 to 23 French in size, according to the type and size of the occluder; they typically include a delivery cable with a mechanism that allows carrying and releasing of the occluder after adequate positioning. Occluder delivery cardiac catheters are used for treatment of PDA, secundum ASD, and, less frequently, VSD using percutaneous techniques.
