Wound Infiltration

Wound infiltration is in fact an extremely effective method for post-operative pain treatment, which is very simple to apply. A local anaesthetic is continuously administered by way of a catheter with multiple perforations, which is positioned in the wound, thereby blocking the distal nerve ends. Aside of the purely anaesthetic properties, some local anaesthetic also has an anti-inflammatory and antibacterial effect.

The great advantage of this economical method is, that the post-operative occurrence of side effects such as nausea and vomiting caused by opioids is reduced. This optimized form of pain therapy is an essential component of all treatment paths for fasttrack rehabilitation.

Based on decades of experience in manufacturing catheters, PAJUNK® has developed InfiltraLong as a special wound infiltration catheter for the continuous treatment of long and deep wounds after operations. The special characteristics of the catheter permit the consistent and precise, on-target administration of local anaesthetic.

There are two infiltration sets available:

  • with a split cannula and optional elastomer-pump
  • or with a Tuohy cannula

Freedom from pain along the complete length

In the development of the InfiltraLong, PAJUNK® has combined decades of experience in the manufacture of catheters with the knowledge concerning the special requirements for pain treatment of large wounds. The main issue is the precise and uniform administration of the anaesthetic. The InfiltraLong catheter is substantially different from other conventional wound infiltration catheters with regard to the following features:


The special arrangement and the precision of the catheter perforation guarantees an absolutely uniform distribution of the analgesic along the complete length of the wound in a radius of 360°, all around the catheter.


InfiltraLong of PAJUNK® is the only wound infiltration catheter which has been provided with an integrated stainless steel helical coil, that will guarantee a uniform flow of the anaesthetic and protection against creasing or buckling during the placement of the catheter. Besides it is radiopaque and visible under ultrasound.


The hub of the catheter has been provided with an additional kink-proof protection. This will also warrant the operational safety of the catheter outside of the wound.
