All catheter materials available have both advantages and disadvantages and the choice of catheter material is often application dependent. While both polyurethane and silicone are biocompatible and are good choices for long-term catheterization, a generalization of advantages and disadvantages as shown below may be helpful in determining which catheter material is most appropriate for your particular application. In cases where compounds show incompatibility with both polyurethane and silicone, the use of less favorable catheter materials such as polyethylene, Teflon® and PVC may be necessary. |

Ordering Information
Catheter tubing can be supplied on 25 foot spools non- sterile (BC series) or in sterile cut lengths (CNC series). Sterile cut lengths are available with or without modificati- ons as shown further back. To assist you with your catheter dimension choice, you will find a catheter specification and conversion chart
Examples: The catalog number BC - 3P indicates a 25’/7.6m spool of 3 French polyurethane tubing, non-sterile. The catalog number BC - 5S indicates a 25’/7.6m spool of 5 French silicone tubing. Examples: To order cut lengths use prefix CNC. The catalog number CNC-2S indicates a sterile cut length of 2 French silicone tubing and CNC-1P indicates a sterile length of 1 French polyurethane.
To order bulk catheter tubing specify the material and French size with the prefix BC (Bulk Catheter). To order sterile cut lengths, specify the material, length, tip configura- tion (round or blunt), and modifications required with the prefix CNC.
Co-Extruded External Infusion Tubing
Co-extruded tubing is extruded with PE on the inside lumen for compound compatibility and PVC on the outside for durability. It is available in 2 sizes.
