06355052 is referenced by 353 patents and cites 10 patents.

The invention relates to a device for closure of defect openings in the human or animal body, which device, in a first state, can assume an elongate shape with a high ratio of length to transverse extent, and, in the implanted state, has a shape with a lower ratio of length to transverse extent, the device being deformable in the radial direction and comprising first arrangements with which the device, in the implanted state, supports itself elastically against the margin of the opening which is to be closed and thereby centers itself approximately within the opening. The device includes second arrangements which, in the implanted state, bear with positive engagement on opposite sides of the tissue surrounding the opening which is to be closed.
