Impress diagnostic peripheral catheters are now available with the added benefit of a hydrophilic coating designed to reduce friction for smoother navigation through tortuous anatomy. The hydrophilic coating is resistant to abrasion and is designed to maintain lubricity throughout the procedure. The Impress catheter line has a stainless steel braided shaft construction designed to provide excellent torque. The tapered tip is designed to seek the ostium of the vessel to be visualized.
