Braid-Reinforced Shaft

Braid-Reinforced Shaft


Engineered shaft with our process ensuring exceptional consistency, realize excellent trackability, pushability, and deliverability for catheter manufacturing.

With our continuous spooling process ensuring exceptional consistency with tighter tolerance, we can design, develop, and manufacture engineered shafts for a complex catheter. The shaft is designed to balance flexibility, pushability, kink resistance, and more, with our capability in a wide range of materials, including PTFE, Pebax®, PA12, stainless steel, etc.


Braided shat consists of three elements, PTFE liner, Braid reinforcement, and the outer jacket. These elements are designed and combined to be a shaft to realize required specifications such as dimensions, flexibility, and other mechanical properties for your catheter manufacturing.

Optional Radiopaque

This tubing may be used where tip, marker, and distal tube. It shows excellent radiographic visibility comparable to PtIr.

optional variable durometer outer tubing

With variable flexibility along their length, this tubing may be used where a proximal push and rotation along with a delicately soft tip is desirable to access the treatment area. For the benefit of seamless flexibility and streamlining process, used to replace manually connecting joint tubing.
