APPLICATIONS

PTCA, Stenting, Guiding Catheters, Dialysis and Other Medical Device Applications
ExtruMed manufactures precision co-extrusion tubing for use in coronary, vascular and other medical device
applications.

FUNCTION

Critical Component for PTCA and Guiding Catheters
ExtruMed’s co-extrusion tubing enables highly precise designs for shafts used in many applications. For example, tubing could have a lubricious inner layer for passing guide wires with a nylon or Pebax® outer layer for balloon bonding. Another function for co-extrusion is radio-opaque stripes for viewing under a fluoroscope or a colored stripe for catheter orientation.

DESCRIPTION

Multi-Layered or Striped Co-Extrusion Tubing
ExtruMed manufactures co-extrusion tubing with multiple layers, colored stripes and radio-opaque stripes. When designing co-extruded tubing, engineers need to use two materials or more that are chemically compatible to prevent the tubing from delaminating. When co-extruded tubing requires incompatible inner and outer layers, a third layer is needed to tie the layers together.

TECHNOLOGY

Tooling, Materials, Process and Quality Control
ExtruMed offers the latest technology and expertise to produce precision co-extruded tubing in both multi-layer and stripe configurations. Both the die design and the extrusion process figure into manufacturing precision co-extrusion tubing. Each material in the tube requires a separate extruder that connects to the co-extrusion die. Process control and tooling design are critical for producing precision co-extruded tubing.

COMPETENCY

Striping, Dual Layer and Tri-Layer Co-Extrusions
ExtruMed is capable of producing co-extrusion tubing in striped, dual-layer and tri-layer configurations. Our process engineers and extrusion technicians have been producing high precision co-extrusions for more than a decade. Our co-extrusion capabilities include
