Catheter Fabrication Processes

Insert/Over Molding

  1. Metal, plastics, and catheters can be inserted and molded into a single unit for improved performance and unique attributes.

Hot Die Necking

  1. The tube is pulled through the heated die and reduced to a defined diameter.
  2. Precisely repeatable lengths.


  1. Lamination is the process of melting the inner and outer jacket materials together to form a composite catheter shaft.
  2. Expertise in multi-durometer tubing lamination.

Hydrophilic Coating

  1. Improve the lubricity and reduce the surface friction to catheter tubing.
  2. Durable and biocompatible.


  1. Single and multi-durometer options available.
  2. Different variations of braid density and configurations.

Coil Winding

  1. Different variations of size, diameter.
  2. Different materials (stainless steel, nitinol, fiberglass, carbon fiber, nylon, etc.)

RF Tip Forming

  1. Different tip configurations (conical tip, step tip, bullet tip, soft tip fusion, beverled tip and many more) on a wide range of tubing size and materials.

Hot Air Bonding

  1. Flexible thermal bonding of catheter tube of dissimilar materials or braided to non-braided section.
  2. Reflow of outer jacket tubing over braided or non-braided inner tube.

Radiopaque Marker

  1. Placement and swaging of Au, Pt/Ir, Pt, Ta, Pd radiopaque marker bands.
