ASD Occluder

Cera™ ASD Occluder is a percutaneous transcatheter atrial septal defect closure device intended for the occlusion of atrial septal defects (ASD) or multi-fenestrated ASDs in secundum position or patients who have undergone a fenestrated Fontan procedure and who now require closure of the fenestration.

PFO Occluder

Cera™ PFO Occluder is a percutaneous transcatheter occlusion device intended for the non-surgical closure of patent foramen ovale (PFO).

PDA Occluder

Cera™ PDA Occluder is a percutaneous transcatheter device intended for the non-surgical closure of patent ductus arteriosus (PDA).

VSD Occluder

Cera™ VSD Occluder is a percutaneous transcatheter ventricular septal defect (VSD) closure device intended for the occlusion of VSD.

ASD Occluder / PFO Occluder / PDA Occluder / VSD Occluder

◇ Nitinol Wire Frame Coated with Titanium Nitride (TiN)

· Decrease the dissolution of nickel ion efficiently for expected long-term biocompatibility.⁽¹⁾

· Promote the growth of endothelial tissue, lessen thrombus complication.⁽²⁾

◇ Strategic Membrane Selection

· The ASD/PFO occluders are sewn with PET membranes, which help to improve the occlusion efficiency by clot formation and fit into lower profile sheath.

· The PDA/VSD occluders are sewn with PTFE membranes, which have denser structure suited for high pressure defects.

◇ Multiple Choices for Different Anatomical Features of the Defects

· Three types of peri-membranous VSD occluders and one muscular VSD occluder are designed for different kinds of VSD.

· The ASD occluders range from 6mm to 42mm.

· The PDA occluders range from 0406 to 2224.
