Clinical Requirements - Precision in Catheter Placement
Precise placement of the catheter is of crucial importance for reliable performance of peripheral nerve blocks. Marhofer et al.1 have analyzed the causes and consequences of catheter dislocation in detail. Among other things, they found a highly significant correlation between the dwell time and the dislocation rate of the catheter for interscalene and femoral nerves.
Primary dislocation
If the catheter is pushed further through the nerve, the anesthetic not only misses its target area, but serious complications such as injury to nerve structures and blood vessels can also occur.
Secondary dislocation
Early mobilization of patients also carries the risk of catheter migration. This can damage vessels or nerves and the efficacy of the regional anesthetic cannot be safely guaranteed.

Relevance of the Catheter Configuration - Soft and Flexible Catheter Tip
An important starting point for reducing the dislocation rate is the quality of the catheter tip. In 2012, Shih et al. found a possible correlation between the stiffness of the catheter material and the dislocation rate during epidural block.2
This is exactly where the PAJUNK® development started off from. The result is the SonoLong SoftSecure catheter, characterized by special design features that result in a soft catheter tip. Further it is equipped with a stylet, a stainless steel helical coil, and three lateral openings.
The soft tip of the SonoLong SoftSecure catheter is intended to ensure precise placement, as the tip is deflected away from the nerve wall due to the wall's resistance.
For the same reason, the catheter is also held back by the surrounding, firmer structures of the fascia and rolls up in the immediate vicinity. Further unintended advancement of the catheter and subsequent dislocation during patient mobilization should be avoided.

SonoLong SoftSecure Set Overview
SonoLong SoftSecure Catheter Features & Advantages
Special Design Features
Make the tip soft and flexible:
- Designed to minimize the primary and secondary dislocation rates.
- Intends to prevent injury from nerves and vessels.
Markings and Graduations
Outlet markings on the catheter for the SonoLong needle 50 mm, 100 mm, 150 mm and six ascending 360° markings in 5-cm increments up to 30 cm:
- Indicates where the catheter tip exits the needle.
- Supports easy control of catheter position.
Catheter Container with Integrated Insertion Aid
Supports one-handed catheter insertion through the needle:
- Catheter placement is possible under sterile conditions since the catheter is protected by the catheter container.
Three Lateral Openings
Arranged around the first 1.1 cm, the tip is closed:
- Developed to optimize even distribution of the anesthetic.
Stylet
- Supports convenient placement.
- Stylet is set back 5 cm from the distal tip.
Integrated Stainless Steel Helical Coil
- Designed for kink resistance and flexibility.
- Innerlumen designed for a high anesthetic flow rate.
SonoLong NanoLine® Needle Features & Advantages
Cornerstone Reflectors
360° graduations on the first 20 mm of the needle in two sections:
- Designed for enhanced visibility of the needle shaft
- and needle tip at steep insertion angles.
NanoLine Coating
Ultra-thin coating in the inner and outer lumen:
- Supports precise stimulation only via the non-insulated needle tip.
