Shape memory alloys (SMAs) belong to a class of shape memory materials (SMMs), which
have the ability to 'memorise'or retain their previous form when subjected to certain stimulus …

Stimulus-responsive materials are able to response to a particular stimulus, such as, heat,
chemical, and light. As such, they are smarter and more intelligent than ordinary materials …

Shape memory alloys, and in particular NiTi alloys, are characterized by two unique
behaviors, thermally or mechanically activated: the shape memory effect and pseudo-elastic …

Shape-memory materials (SMMs) are characterized by their unique ability to remember and
recover their shape in response to external stimuli. Over recent decades, the use of SMMs in …

Objectives: This study sought to compare the safety, efficacy and clinical utility of the
Amplatzer septal occluder (ASO) for closure of secundum atrial septal defect (ASD) with …

Objectives: We sought to review and report initial and one-year efficacy and safety results of
the multicenter USA Amplatzer ductal occluder (ADO) device trial. Background …

Aim: To evaluate the safety and efficacy of transcatheter closure of secundum atrial septal
defects (ASD) with the Amplatzer septal occluder. Methods: 236 consecutive patients with a …

After being severely and quasi-plastically deformed, shape memory materials are able to
return to their original shape at the presence of the right stimulus. After a brief presentation …

In patients with congenital heart disease the right ventricle (RV) may support the pulmonary
(subpulmonary RV) or the systemic circulation (systemic RV). During the last 50 years …

Objectives: Results and complications of surgical versus transcatheter treatment of atrial
septal defect in the current era are compared. Methods: All consecutive patients with a …
