What are the lengths of guidewires?

A medical guidewire is a very small tool used in interventional procedures to guide a catheter through a blood vessel, heart chamber, or other tube in the body. The length of the guidewire may vary greatly depending on the needs of the procedure and the target site. Here are some common guidewire lengths:

80-120cm: These shorter guidewires are often used for percutaneous coronary intervention (PCI) or other interventions that target a closer site.

150-180cm: These lengths are more commonly used for cardiac catheterization laboratory procedures or other interventional procedures that require a longer guidewire to reach the target site.

200-300cm: These extra-long guidewires are mainly used for procedures that involve traveling from one side of the body to the other, such as surgeries across the heart or certain specialized interventional procedures.

The diameter of medical guidewires is usually measured in French (F) or millimeters (mm). In addition to length and diameter, the guidewire’s stiffness, coating, tip shape and maneuverability are also important factors that physicians consider when selecting a guidewire.

When selecting a guidewire, the surgeon decides which length and type of guidewire to use based on the type of surgery, the patient’s anatomy, and the expected difficulty of the procedure. Therefore, the length of the guidewire is selected based on the specific clinical application. If specific guidewire product information is required, it is recommended to consult a specialized medical device supplier or manufacturer.
