Braided Catheter Capabilities

  • Catheter shafts and sheath assemblies
  • Precise control of braid angle, coil pitch, and polymer properties
  • Patterns (standard, diamond, and half load)
  • 16- and 24-carrier braiders
  • 1-,2-, or 3-wire ends/carrier
  • Fully programmable variable braid density/PPI
  • Longitudinal (tri-axial) wires; up to 8 longitudinal wires/shaft
    • Steel
    • Nitinol
    • High-tensile, nonmetallic fibers

Lubricious / Low Friction Catheter Solutions

Lubricious surfaces are a critical feature of every minimally invasive device. Low friction lumens allow devices to readily access tortuous anatomy and tight spaces with a minimum of force. 

Spectrum Plastics Group has decades of experience in manufacturing minimally devices, and offers a range of lubricious catheter materials that are fast, reliable, and low friction.

Multilumen Delivery Systems

A multilumen delivery system manufactured by SPG

Our proprietary processes allow us to manufacture braid- or coil-reinforced multilumen catheters with greater precision and lower cost. These catheters are commonly used in structural heart therapies and electrophysiology devices.

  • Up to 20 lumens
  • Coil reinforced
  • PTFE lined
  • FEP lined
  • Polyimide lined
  • May be combined with deflectable catheter design

Low-Profile Delivery Systems

As intravascular reconstruction drives demand for increasingly thinner catheter walls and devices with ultralow profiles, we have the capabilities to design and manufacture devices to meet your needs.


  • Thin-wall, high-pressure dilation balloons
  • Sub-ultrathin-wall extruded tubing
  • Embedded ultrafine wire-reinforced tubing
  • Low-profile steerable tips
  • Catheters, liners, and coatings
