Abstract: An improved vascular access dilator apparatus consisting of a wire, a blade with a locking safety mechanism, and straight but malleable dilator with a smooth surface having a lumen just large enough for the wire to slide easily in and out. The safety sheath covers the blade once an incision in the dermis is made, thereby protecting both the patient and caregiver.

Abstract: An improved vascular access dilator apparatus consisting of a wire, a blade with a locking safety mechanism, and a malleable, tapered dilator having a lumen just large enough to accommodate said wire sliding easily in and out. The tapering of said dilator being accomplished by and improved by the joining of straight dilator segments (that decrease in diameter in the direction of the tip of the dilator) by angled segments located between each straight segment. In one embodiment, A safety sheath covers the blade once an incision in the dermis is made, thereby protecting both the patient and caregiver.
