InQwire® Guide Wires Features: PTFE precoats the entire InQwire guide wire surface to provide soft, constant coverage. It prevents the wire from peeling off. It prevents friction thus it can be tracked easily, provides lubrication, and is long-lasting. Most importantly, its J-tip memory need not be refilled with the J straightener. Catheter and sheath compatibility is obtained with the tight guide wire tolerance. The InQwire also comes with heparin coating to reduce clotting of blood.
