BACKGROUND Despite two decades of research, a transcatheter atrial septal defect closure
device is not available for clinical use. We have designed a new superelastic Nitinol-Dacron …

The Sideris buttoned occluding device10 is made of a polyurethane foam occluder with a
Teflon coated wire skeleton, which is positioned in the left atrium, and a polyurethane foam …

Recent experience with the spring-loaded patent ductus arteriosus (PDA) occluder has
demonstrated several advantages of this device in the closure of intracardiac defects …

The Monodisk, a device to facilitate percutaneous closure of cardiac septal defects, was
developed and tested in vitro and in vivo. Atrial septal defects (8–10 mm) were created in …

During a 21-month period ending in August 1991, 12 patients underwent transcatheter
closure of atrial septal defect (ASD) with a “buttoned” device through an 8Fr sheath, using an …

A clinical trial was conducted of the buttoned device for transcatheter closure of ostium
secundum atrial septal defect. Occlusion was attempted in 57 patients aged 1 to 62 years …

Various devices for transcatheter ASD closure are undergoing clinical trials. Each new
device claims advantages in terms of safety and efficacy over earlier devices. We report …

Transcatheter closure of secundum atrial septal defect (ASD) using clamshell or buttoned
devices is accompanied by a high incidence of residual shunt. Recently, a new self …

OBJECTIVE To review the outcomes of transcatheter closure of atrial septal defects using
the Cardio-Seal implant. DESIGN A prospective interventional study. SETTING Tertiary …

Several devices are available for transcatheter occlusion of atrial septal defect. This report
describes the international experience with the buttoned device. During a 4.5-year period …
