| 摘要 |
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 ration of length to transverse extent, the device being deformable in the radial direction and comprising first arrangements (8, 24, 31) with which the device, in the implanted state, supports itself elastically against the margin of the opening which is to be closed and thereby centres itself approximately within the opening, characterized in that the device comprises second arrangements (7, 9, 20, 21, 32) which, in the implanted state, bear with positive engagement on opposite sides of the tissue surrounding the opening which is to be closed.
