The MRWire Guide Wire is a sterile, disposable guide wire for the introduction and/or placement of diagnostic or interventional devices. The MRWire is constructed from a high strength core composite of glass fibers and polymers, protected by a high-strength aramid fiber mantle and covered with a PTFE extrusion. The hydrophobic extrusion reduces intravascular friction in devices such as catheters. The distal tip of the MRWire is marked with discrete ring markers for MRI and X-Ray visibility and comes in different configurations such as straight and angled. Guide wires are supplied sterile and non-pyrogenic. The MRWire’s diameter is 0.035” (0.89 mm).
A long, thin, sterile wire intended to be percutaneously placed into the cardiac vasculature (ventricles or coronary vessels) to function as a guide for the introduction, positioning, and/or operation of a device (e.g., catheter, pacing lead); it may also be used in the peripheral vasculature. It may be made of metal (e.g., stainless steel, Nitinol), or polymer and/or glass materials to provide MRI-compatibility, with or without coating, and is available in a variety of distal tip designs. It is used for various diagnostic and interventional procedures, and may include devices used to facilitate manipulation (e.g., torque device). This is a single-use device.
