Variable Durometer tube

Product catalog summary
Overview: The document discusses the technical specifications and advantages of variable durometer tubing and braid-reinforced shafts used in medical catheters. The focus is on the continuous extrusion process that enhances the performance and reliability of these components.
Variable Durometer Tubing:
  • The tubing features a linear transition from a soft tip to a hard proximal end, improving blood vessel trackability and reducing costs.
  • Specifications include inner diameters ranging from 0.03" to 0.10" and wall thickness as low as 0.0024".
  • Materials used include Pebax® and Vestamide®.
  • Applications are primarily in micro and delivery catheters for neuro, peripheral, and interventional oncology fields.
Braid-Reinforced Shaft:
  • Composed of a PTFE liner, braided core, and outer extrusion tube, offering flexibility, pushability, and kink resistance.
  • Materials include PTFE, Pebax®, PA12, and stainless steel.
  • Specifications detail tightly controlled wall tolerances and optional features like etched or thermoplastic tie layers for adhesion.
Additional Features:
  • Optional variable durometer tubing provides seamless flexibility, replacing manually connected joint tubing.
  • Radiopaque resin tubes offer excellent radiographic visibility, comparable to PtIr, for use as tips, markers, or distal tubes.
Material Specifications:
  • Various materials are used, including Nylon, Polyurethane, LLDPE, HDPE, and more, each with specific dimensional limits and treatment options.
  • Wire specifications for braiding include SS304, Tungsten, 66PA, LCP, PEEK, PPS, and PFA, with details on wire dimensions and terminal treatments.

Variable Durometer tube-1

Datasheet : Extrusion : Variable Variable Durometer tube Continuous stiffness change Distal 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.
