An intra-arterial occluder according to the invention exhibits a central elongated portion being comparatively stiff, e.g., by being thicker, and an outer rim portion being more flexible. The occluder is passed through the puncture, and is oriented such that the axis of the central portion is generally coaxial with the vessel. When retracted, the central portion will rest against the vessel wall at two diametrically opposed areas around the puncture, and along the length of the vessel. These areas represent the strongest areas around the puncture, and will therefore be able to safely carry the retracting force. At the same time, the thinner circumferential rim portion, which is easily foldable to fit into an insertion tool, adapts to the vessel wall and acts as an efficient sealing.
