The Seldinger technique is often used to create a percutaneous access for an interventional or diagnostic procedure: The Seldinger needle is used to puncture the artery in order to insert a guide wire into the vessel. The correct position of the needle is crucial to minimize the risk of injury to the vessel and skin layer. However, patients are increasingly obese and the shaft length is not sufficient to ensure correct placement in the vessel. With their extended shaft, our Seldinger needles solve this problem as they can penetrate a larger layer of skin to reach the vessel. Our Seldinger needles are made of proven quality Easy Glide 304 stainless steel. A thin-walled tube and high-precision grinding ensure smooth insertion of the needle with minimal risk of injury to the vessel wall. The extended shaft of the 18G needle (for femoral access) measures 11cm instead of the conventional 7cm, the shaft of the 21G needle (for radial access) measures 7cm instead of 4cm.
