Variable durometer tube

Variable durometer tube

Lumen

Our automated process eliminates labor and welded points for smooth transition between soft tip to a hard proximal end for excellent blood vessel trackability.



Variable durometer throughout the tube's length provides a linear transition between a delicately soft tip with a hard proximal end. Our continuous extrusion process eliminating labor and welded points of the manually assembled tube, causing the misaligned segment to fail, bring seamless transition, reducing cost, and better blood vessel trackability to your catheter. This process also can be validated and less susceptible to lot-to-lot variations. Ideal for catheter required soft tip with pushability at a proximal end.


comparison of stiffness change

A comparison graph shows how stiffness changes from a soft tip to a hard proximal end, compared to a manually assembled tube.

Here is a comparison of its increased bending smoothness.
