A medical device and method for closure of a puncture in a body lumen are disclosed. The device has an aggregate (10) of a support structure (20) and a substantially fluid tight patch member (30) attached thereto at an attachment unit (40). The aggregate has a first, temporary delivery shape, for delivery to an interior of said body lumen and to be subsequently subjected to a change of shape to a second shape, which is a tubular shape. When delivered in said body lumen, the patch member is arranged radially outside of said tubular support structure and arranged towards an inner tissue wall of the body lumen. The aggregate is the detached from a delivery device and said puncture is intraluminally closed in a leakage tight manner, advantageously supported by a physiological pressure of a body fluid in said body lumen. Rotational orientation is detectable by fiducial markers. A compact delivery cinfiguration is provided by the patch being attached to the support structure at a single radial attachement position only.
