GUIDEWIRES

There are three types of guidewires:

• Solid Core Wire: The central wire is encased by a metal 'spring' coil.
• Mandrel Wire: The outer spring coil is at one end
• Ribbon Wire: The spring coil encases both the core wire and a ribbon wire

There are three types of spring wire guide tips:

         

• Straight tip, with straight, flexible tips at both ends reducing the risk of trauma to the blood vessel (not shown)
• J tip, with a straight, flexible tip at the proximal end bent tip at the distal end, providing even more flexibility and protection for the vessel during insertion.
• Angled tip, with a straight, flexible tip at the proximal end and a bend of less than 90 degrees on the distal end, helping the guidewire steer during placement.

Spring wire guides also vary in materials, diameter, length, coatings and position indicators (marked or unmarked).

The guidewire assembly consists of:

• The advancer, which straightens the J tip to help introduce the wire into a Raulerson® Syringe or needle.
• The Raulerson® Syringe, which provides a closed insertion system, reducing the risk of air embolism and blood exposure.
