A stitching assembly comprising: an upper cradle; an upper carriage configured to support the upper cradle for movement along a curved path between an advanced position and a retracted position relative to the upper carriage; an upper needle supported by and extending distally from the upper cradle; a first suture supported by the upper needle and fed from a suture tensioner, the upper cradle and the upper carriage being configured to draw the first suture through tissue when the upper cradle moves towards the advanced position, the upper needle including an outer surface and a distal end and the upper carriage including an upper plow positioned adjacent the distal end of the upper needle, the upper plow of the upper carriage and the outer surface of the upper needle being configured to capture a portion of the first suture therebetween as the upper cradle is moved towards the advanced position to form a first stitch loop in the first suture when the upper cradle is moved from the advanced position towards the retracted position,; a lower cradle; a lower carriage configured to support the lower cradle for movement along a curved path between an advanced position and a retracted position relative to the lower carriage; a lower needle supported by and extending distally from the lower cradle; and a second suture supported by the lower needle and fed from the suture tensioner, the lower cradle and the lower carriage being configured to draw the second suture through tissue and the first stitch loop when the lower cradle moves towards the advanced position, the lower needle including an outer surface and a distal end and the lower carriage including a lower plow positioned adjacent the distal end of the upper needle, the lower plow of the lower carriage and the outer surface of the lower needle being configured to capture a portion of the second suture therebetween as the lower cradle is moved towards the advanced position to form a second stitch loop in the second suture when the lower cradle is moved from the advanced position towards the retracted position. an upper cradle; an upper carriage configured to support the upper cradle for movement along a curved path between an advanced position and a retracted position relative to the upper carriage; an upper needle supported by and extending distally from the upper cradle; a first suture supported by the upper needle and fed from a suture tensioner, the upper cradle and the upper carriage being configured to draw the first suture through tissue when the upper cradle moves towards the advanced position, the upper needle including an outer surface and a distal end and the upper carriage including an upper plow positioned adjacent the distal end of the upper needle, the upper plow of the upper carriage and the outer surface of the upper needle being configured to capture a portion of the first suture therebetween as the upper cradle is moved towards the advanced position to form a first stitch loop in the first suture when the upper cradle is moved from the advanced position towards the retracted position,; a lower cradle; a lower carriage configured to support the lower cradle for movement along a curved path between an advanced position and a retracted position relative to the lower carriage; a lower needle supported by and extending distally from the lower cradle; and a second suture supported by the lower needle and fed from the suture tensioner, the lower cradle and the lower carriage being configured to draw the second suture through tissue and the first stitch loop when the lower cradle moves towards the advanced position, the lower needle including an outer surface and a distal end and the lower carriage including a lower plow positioned adjacent the distal end of the upper needle, the lower plow of the lower carriage and the outer surface of the lower needle being configured to capture a portion of the second suture therebetween as the lower cradle is moved towards the advanced position to form a second stitch loop in the second suture when the lower cradle is moved from the advanced position towards the retracted position.
