The C-Port®-CT Port Catheter System.
Implantable venous port - CT compatible.

The C-Port®-CT, our economical plastic version of an implantable port that is also suitable for high pressure infusion.

The C-Flow® chamber of the C-Port®-CT differs from most conventional ports with a cylindrically shaped port chamber by the optimized inner chamber geometry and the baseline outlet. This results in improved flow dynamics and allows, in addition to standard applications, the performance of computed tomography with contrast medium (contrast-CT).

 
That this is also measurable can be seen here

Due to the transparent septum of the NuPort®, which has been adopted in the C-Port®-CT, it is possible to look into the chamber during implantation to monitor the venting and flushing of the port.

The lightweight, tissue-compatible plastic is CT/MRI compatible.

a) Clear septum and baseline outlet simplifies port venting and minimizes the risk of air embolism.

b) The C-Flow® chamber improves flow dynamics and reduces the risk of occlusion.
Identification
Identification
The C-Port®-CT is characterized by the special heart shape. This is also clearly visible in the X-ray image. Furthermore, the heart shape supports the blunt preparation of the port pocket during implantation.
Connection
Connection
The connection mechanism enables safe connection of the catheter to the port base via audible and tactile feedback. These two detection functions ensure that the connection is properly secure.
Localization
Localization
The raised edge of the C-Port®-CT makes it easy to palpate the port and locate the septum for infusion or CT application.

The measurable difference

In the FDA guidelines for the approval of ports, a defined measurement setup* is described, the so-called "Clearing Index". This indicates how much flushing volume is required to flush out (clean) a port chamber without leaving any residue. This test has also been adopted in the ISO standard for port catheter systems 10555-6**.

This can be used to illustrate the measurable differences between different port designs.

In a study by Norfolk Medical Inc., USA ***, the respective flushing characteristics were compared in a measurement of four different port systems. The difference between the system with a conventional cylindrical port chamber and central catheter outlet and our NuPort® chamber geometry with tangentially positioned catheter outlet is clear.

Almost 40% more flushing volume is required with a conventional port for residue-free flushing.

The chamber geometry therefore makes the decisive difference in the flushing (cleaning) of port systems. Under certain circumstances, this is precisely the difference that prevents occlusion of the port system.
