Abstract
In one aspect, the present invention provides a device for occluding an aperture in a body, for example, a patent foramen ovale (PFO), including a first side adapted to be disposed on one side of the septum and a second side adapted to be disposed on the opposite side of the septum. The device has an elongated, low-profile delivery configuration and a shortened, radially expanded deployment configuration. The first and second sides are adapted to occlude the aperture upon deployment of the device at its intended delivery location. The device also includes a radially expandable center portion. In some embodiments, the center portion includes a plurality of ribs provided by slits in device. The ribs expand radially when the device is deployed. The expandable center portion facilitates the positioning of the device in the aperture. The device can be secured in the deployed configuration using a catch system.
