Nit-Occlud® PDA is a system for transcatheter occlusion of Patent Ductus Arteriosus (PDA) with spiral coils. The system consists of a spiral coil mounted in a straightened fashion on a flexible delivery system including a disposable handle. The Nit-Occlud® PDA has a cone in cone configuration which results from the fact that the proximal windings of the coil are wound the reverse direction. Nit-Occlud® PDA is available as Flexible and Medium Type. The flexible and medium types are pre-loaded into the transportation sheath.
An implantable disk-like device intended to be used for the minimally-invasive closure of cardiac defects and deployed using a dedicated delivery catheter/sheath. It is made of wire mesh [e.g., nickel-titanium alloy (Nitinol)], and possibly additional materials (e.g., polyester), and is typically self-expandable. The device is used to treat cardiac disorders that may include (but not limited to) atrial septal defect (ASD), ventricular septal defect (VSD), patent foramen ovale (PFO), or patent ductus arteriosus (PDA). Disposable devices dedicated to implantation may be included with the implant.
