Abstract
A closure device for a patent foramen ovale (PFO) has proximal and distal occlusion members for applying compressive forces to tissue on opposite sides of septal defects to help close the defects. The devices are collapsible for delivery and deployment, and can be easily retrieved and redeployed or repositioned if needed.
Claims24
An apparatus comprising:
- a patent foramen ovale (PFO) closure device having a deployed configuration for providing compressive force to septum primum and septum secundum and including:
- a central body for extending through the PFO,
- a first end cap, and
- first and second loops on one side of the PFO, each of the first and second loops extending from the central body to the first end cap, each of the first and second loops defining a plane substantially parallel to septum primum and septum secundum such that the first and second loops apply a force, perpendicular to the plane, to one of septum primum and septum secundum.
