Patent Images
1. A septal defect closure device, comprising:
- a proximal occluder including a plurality of outwardly extending proximal arms supporting a proximal occlusion shell;
a distal occluder including a plurality of outwardly extending distal arms supporting a distal occlusion shell; and
a centering mechanism secured between said proximal occluder and said distal occluder to center said proximal and said distal occluders about a defect, said centering mechanism comprising at least two centering members, each of said centering members secured between a separate one of said proximal arms and a corresponding one of said distal arms, at least one of said centering members comprising an elastomeric material.

Abstract
A self-centering umbrella-type septal closure device which includes a proximal and distal occluder each having a plurality of arms supporting the occlusion shells. Each of the proximal and distal support arms have at least three coils any one or more of which is secured by a centering mechanism so as to control the positioning of the closure device so that it is centered about a defect.
