Tiny guide wires are designed to navigate vessels to reach a lesion or vessel segment. Once the tip of the device arrives at its destination, it acts as a guide that larger catheters can rapidly follow for easier delivery to the treatment site.

Many workhorse guide wires are indicated to facilitate the placement of balloon dilatation catheters during percutaneous transluminal coronary angioplasty (PTCA) and percutaneous transluminal angioplasty (PTA). PTCA refers to angioplasty performed in the coronary arteries, while PTA refers to angioplasty performed in other arteries.

Wires are characterized by their pushability, steerability, torque and opacity. Pushability is the amount of force needed to advance the wire. Steerability is the ability and responsiveness of the wire tip to navigate vessels. Torque is the response of the wire to turning by the operator when navigating vessels. Its opaci...
