A medical closure device (20) is provided, which comprises a tubular member (21) provided with a first set of struts (22) that extend between a first end portion (24) and a central portion (25) and second set of struts (23) that extend between said central portion and a second end portion (26), and each strut being provided with a section (27, 28) that can act as a hinge, such that said closure device being movable between a first elongated tubular configuration and a second configuration in which the first and second end portions have been moved towards each other such that the first and second struts have moved radially away from a longitudinal central axis of the closure device, and wherein the two arms of at least one of the strut sets, in the first configuration, are arranged with positive tilt angle to each other to thereby ensure that the second configuration can be achieved. In addition, the hinge region is constructed such that upon folding of the hinge, a middle longitudinally extended section (27b, 28b) will fold outward, thereby adding to the total reach of the device in supporting itself on the underlying tissue, creating a more secure final position of the device when sealing e.g. a septal defect in the heart.
