Contiplex® C

Echogenic catheter-over-needle system for continuous nerve block

The Next Evolution in Ultrasound Guided CPNB Catheter Placement

Catheter-over-needle design – Contiplex® C provides the power and flexibility of a catheter with the familiarity of a single shot.

  • Deliberate – The catheter tip can be purposely directed to an exact location, without the need to thread.
  • One step – Once the catheter and needle are in the right location, simply remove the needle. The catheter is already placed.
  • Linear – Needle and catheter are introduced in a straight line making it easier to maintain both in the ultrasound beam.
  • Echogenic – Catheter is ultrasound visible. After needle removal, the catheter can be identified because of its straight trajectory.
  • Help reduce leakage – When the needle is removed, the catheter is designed to seal the puncture site to help reduce leakage.
  • Securement with a shorter catheter – Help make catheter securement easier and reduce the potential of catheter knotting. The short 18.7cm catheter is designed for easy handling and securement.
  • Help improve patient comfort – Contiplex® C’s 30° or 15° bevel and small 25G gauge size is designed to be less traumatic to the patient when compared to a larger 17 or 18G Tuohy.

Additional information

Who Can Benefit

Contiplex C is best suited for: Blocks < 6cm

  • Contiplex C is indicated for blocks equal or less than 6cm in depth
  • Depending on your practice, Contiplex C may take a leading or Supplementary role


Providers starting or expanding CPNB programs

  • Making the transition from single shot to catheters can be challenging particularly with limited support and teaching
  • Contiplex C provides the power and flexibility of a catheter with the familiarity of a single shot
  • Contiplex C can help motivate additional providers to utilize CPNB 


Experienced providers

  • Some providers already have a well established technique that is proven and works
  • Contiplex C’s potential for reduced catheter leakage and ease of placement may promote its use for specific blocks


Private Practice groups

  • No block room, Block Nurse, Acute Pain Team or time to place a catheter?
  • Placing the Contiplex C catheter deliberately in one step under ultrasound guidance may help facilitate placement in private practice. 


Residency programs

  • Need to get multiple residents trained but want to try and reduce the learning curve?
  • Contiplex C may help facilitate the bridge between Tuohy based catheter through needle systems or may be an outright solution



One-Step Concept


  • Advance the needle & catheter together at the same time using the new movable grip, called the Control Grip (C-Grip).


Linear Catheter Placement

  • Placing both the needle and catheter together reduces the chance of losing the catheter when threading with a more traditional catheter over needle technique.


Catheter Placement

  • One Step Catheter Placement. With one hand on the catheter, simply remove the needle – the catheter is already in the optimal location.


Never lose sight of what’s most important to you

  • When the needle is removed, you can see the catheter, and it’s exactly where you left it!
