InfiltraLong Catheter and Fuser Pump for infiltration analgesia


Continuous Wound infiltration Benefits 
• simpler, safer and more economical than other procedures,
• avoids the risk of motor blocks,
• enables earlier mobilisation,
• offers the option of post-operative pain treatment
• reduces the need for opioids. 1


Design features
• clear markings on catheter to identify perforation segment for correct placement in lesion
• catheter is white for increased visibility
• catheter available in lengths from 420 to 900mm to suit a range of lesions
• catheters of varying perforated segment length available,  in the range, 25mm-300mm.
• the only wound infiltration catheter that can be combined with all commercial pumps, be they a portable or stationary type
• large inner lumer for free flow of anesthetic


Even distribution of anesthetic
InfiltraLong has microperforations running in a spiral pattern about the catheter, closely & evenly spaced. This ensures fine, even and close distribution of the anaesthetic along the entire length of the perforated segment, and in a radius of 360° around the catheter.
The amount of anesthetic exiting the catheter is equal at both the proximal and distal ends of the perforation segment, ensuring even distribution of anaesthetic throughout the infusion site.


An integrated stainless steel helical coil ensures the catheter remains open along its entire length even if tissue is pressing on it. Additionally catheter is both echogenic and radiopaque -its position can be checked at any time - even if the wound has been closed.

InfiltraLong catheter and Fuser Pump


Catheter introduced by Split Cannula
Left: Skin puncture. The split cannula is advanced until the tip is visible in the wound. The lock is loosened, and the metal cannula retracted.
Center: Introduction of the catheter. The catheter is introduced through the split cannula in such manner so that the complete perforated segment is situated in the wound, resulting in uniform anesthetic distribution. Care must be taken in catheter placement to avoid blood vessel injury.
Right: The Split cannula is now separated and removed.
Not Illustrated: Following removal of split cannula, the filter is connected to the catheter. A first injection of approx. 10ml of local anesthetic is administered before securing the catheter and closing the wound. This serves to ensure that the infusion is proceeding successfully and that post-operative pain treatment can commence. Catheter is ably secured with EpiGuard fixation


Catheter introduced by Tuohy needle or Tunnelor
