Abstract:
1. A medical device for closing a puncture opening in a body lumen from an interior thereof, said device comprising: an elongate delivery unit comprising a delivery wire; and an aggregate comprising: a support structure having a temporary delivery shape configured for delivery to the interior of said body lumen through said puncture opening and subsequently to be controllably subjected to a change of shape to a tubular shape after being delivered into said body lumen, and a patch member attached to said support structure at an intermediate portion between two opposite ends thereof; wherein said delivery wire is radially releasably attached to said aggregate at an area covered by said patch member at an attachment point intermediate between ends of said patch member and detachable therefrom upon deployment of said aggregate in said body lumen such that, said patch member is configured to be centrally aligned in said puncture opening when said delivery wire is withdrawn; wherein, with said support structure in said delivery shape, said patch member is substantially fluid tight and is sized and shaped to be positioned against an inner tissue wall of said body lumen at a site of said puncture opening and to extend over said puncture opening; and wherein said delivery wire extends in a direction radially from said aggregate and is configured to extend through said puncture opening, such that said puncture opening is controllably sealed by said patch when said delivery device is drawn in a direction out of said puncture opening and said patch is tightened over said puncture opening before said support structure changes shape from the temporary delivery shape to the tubular shape.
