CT-Port II

The C-Port® port catheter system is our economical variant of a conventional port.

The C-Port® with C-Flow® chamber differs from most conventional ports with cylindrically shaped port chambers by the optimized geometry of the inner chamber and the baseline outlet. Improved flow dynamics are ensured here.

That this is also measurable can be seen here

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

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.
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.

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.

NuPort® chamber, significantly improved flushing efficiency
C-Port® chamber, improved flushing efficiency
Conventional cylindrical port chamber, inferior flushing efficiency
