Abstract
A method for closing a body opening in a patient is disclosed. The method comprises positioning a delivery catheter within the body opening. The delivery catheter includes a closure device comprising a distal occluding body and a proximal occluding body. The closure device is collapsibly disposed within a distal end of the delivery catheter. The method further includes deploying the closure device from the delivery catheter about the body opening such that a distal frame of the distal occluding body expands to its expanded configuration at a distal end of the body opening and a proximal frame of the proximal occluding body expands to its expanded configuration at an opposing proximal end of the body opening.
