Medical tube Proximally Reinforced Shafts

Braid-Reinforced Shaft

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.

Construction

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.
