When Using Intisil or Hydrocoat catheters on Vascular Access Ports it is recommended to use the attachable (AC) version of the port to keep the benefit of the rounded tips.

All our Vascular Access Ports can be supplied with:

  • Preattached catheter: the catheter length can only be trimmed from the distal tip. This catheter configuration is recommended for catheters smaller than 3 french.


  • Attachable catheter: The catheter length can only be trimmed from the proximal tip. This catheter configuration is essential if the distal tip is rounded or specialized.


Ordering codes: Please use the ordering code for the chosen port combined with the code for the chosen catheter. Example: If you want to order a Rat-O-port with Hydroocat 3 french, the order code will be: ROPAC-3H.

  • ROP -port model
  • AC- for attachable catheter
  • 3H - for 3 french Hydrocoat

More information on implantation, maintenance and flushing of the ports can be found on our VAP maintenance page.


A noteworthy tip ... when accessing a Vascular Access Port, especially when withdrawing, be sure the needle tip hits the base of the port. You will hear a 'click' when the needle hits the base of the port that will confirm the needle eye/heel has cleared the septum. Maintain positive pressure as the natural tendency is to pull back on the needle when it hits the metal base. If the deflected tip/needle does not totally clear the septum, withdrawal will be difficault due to the occlusion caused by the "partially occluded needle eye".
