Ultrasound guided central venous and arterial punctures

The use of ultrasound to position central venous catheters is a proven way of improving patient welfare 1 while reducing the rate of failed puncture attempts.2 VascularSono is a vascular puncture cannula developed by PAJUNK® that has outstanding ultrasound visibility. The ultrasound waves are very clearly reflected in this procedure both in-plane and out-of-plane by the cannula shaft and the tip, even if the insertion angle is steep.3

Sophisticated layout

For a clear identification of the cannnula tip, the Cornerstone reflectors are offset at 60° at the distal end around the cannula and attached at two sections each of 10 mm length. This ensures optimum 360° visibility under ultrasound.

Cornerstone geometry improves echogenity

The Cornerstone reflectors are designed in a way that guarantees direct or indirect reflection of the ultrasound waves even at very steep insertion angles.1

Echogenic cannula tip

Cannula design: Echogenic cannula tip by facet grinding with two inclination angles. Excellent gliding properties in all fabric layers.
