A device and a method for sealing an opening in an anatomical structure is provided. The device includes a flexible tube including a proximal portion and a distal portion extending along a common axis. The proximal portion is coupled to the distal portion by a central portion, which extends from a distal end of the proximal portion to a proximal end of the distal portion. The central portion bends away from the axis along a curve so that the distal end of the proximal portion faces the proximal end of the distal portion across a gap formed by the central portion. In use, the device is inserted through an opening in a wall of the anatomical structure so that a portion of the wall is received within the gap. A needle, that is attached to a first length of suture, is then inserted through a first needle lumen to an opening formed in the distal end of the proximal portion and crosses the gap penetrating the wall to enter a needle receiving chamber that is formed in the distal portion. The needle bends around the needle receiving chamber to exit the needle receiving chamber at a point opposite the second needle lumen. The needle is withdrawn from the structure via the second needle lumen and the device is rotated to a second position where a second length of suture is drawn through a second portion of the wall and secured to the first length of suture to seal the opening.

[ What is claimed is:] [16.] A device for sealing an opening in a wall of an anatomical structure comprising:a flexible tube including a proximal portion and a distal portion extending along a common central axis, wherein the proximal portion is coupled to the distal portion by a central portion, the central portion extending from a central portion proximal end that is coupled to a distal end of the proximal portion to a central portion distal end that is coupled to a proximal end of the distal portion, wherein a central axis of the central portion bends away from the common central axis along a curve so that the distal end of the proximal portion faces the proximal end of the distal portion across a gap formed by the central portion with the common central axis extending between the proximal and distal portions through the gap, wherein, when the device extends through the opening in an operative position, the wall of the anatomical structure is received within the gap;a first needle lumen extending through the proximal portion substantially parallel to the common central axis from a proximal end of the proximal portion to a first opening formed in the distal end of the proximal portion; anda second needle lumen extending through the proximal portion substantially parallel to the common central axis from a proximal end of the proximal portion, around the curve of the central portion to a second opening formed in the proximal end of the distal portion, the second opening facing the first opening, so that when a flexible needle is passed through the first needle lumen to exit from the first opening, the flexible needle crosses the gap and enters the second opening.
