A vascular suturing device is disclosed which includes an elongated tubular body defining opposed proximal and distal end portions and having a longitudinal axis extending therethrough, the body including an inner tubular member, an outer tubular member and a central tubular member disposed between the inner and outer tubular members. The inner tubular member and the central tubular member are mounted for movement relative to the outer tubular member about the longitudinal axis of the body for sequentially driving a pair of suture needles through the wall of a blood vessel to close an incision formed therein. A vascular dilator having a tapered distal tip portion is supported within the inner tubular member and is dimensioned to extend beyond the distal end of the inner tubular member for positioning the suturing device at the incision in the wall of the blood vessel. The dilator is configured to direct blood flow from the distal portion of the dilator to a location remote from the blood vessel for observation to confirm the location of the device.
