Non-allergic

More radiopaque

Key highlights

Self-expanding, double disc device which with unique Platinum nanocoating
4, 7, & 10 mm waist lengths available
Available in multiple lengths to match the types and locations of the ventricular septal defects to close membranous and muscular defects
Discs are filled with polypropylene fabric which assists thrombogenicity
Ability to recapture and redeploy^*

Design:

Left ventricular disc diameter (Ø1)
Right ventricular disc diameter (Ø2)
Waist diameter (Ø3)
Waist length (L)

Thickness of the septum is considered for selecting the length of the device

^*Recapture and redeployment is possible only if delivery cable is securely connected to the disc.
