SonoLong Sono
The Kink Resistant Catheter with Stainless Steel Helical Coil
The SonoLong Sono set is a joint development of PAJUNK and Dr. Meier. It is equipped with an integrated stainless steel helical coil and is suitable for long-term treatment in pain therapy and nerve blocks.
The SonoLong Sono sets are available in three different needle types: with the standard Tuohy tip, Facet tip, and the SPROTTE® Special Tip. All three needle options are equipped with the proven Cornerstone Reflectors for improved visibility under ultrasound monitoring.
The catheter material itself is characterized by its flexibility and improved echogenicity, and is supported by a metal spring.
