TFX Medical OEM microcatheters are available in a wide range of easily customizable configurations to meet your needs. Whether you require PTFE lined, multiple durometer, variable shaft diameter, imbedded marker bands, or thin wall construction, you can count on our microcatheters for exceptional torque control, kink and pressure resistance, lubricity, and "push-ability".

TFX Medical OEM microcatheters are available with flat or round wire, and coil reinforced configurations. Flat wire is generally used for thin walled applications where "anti-kink" performance is critical. Coiled shafts are more flexible and kink resistant, but they do not have the same torque capabilities as a braided shaft.

Of course, if you have any questions, please contact your TFX Medical OEM representative. They'll be happy to answer any questions or put you in touch with one of our highly skilled design engineers.
