Application

Laser Processing

State-of-the-art laser welding and micromachining capabilities add value to our catheter and guidewire manufacturing, giving you more options for materials and design.

Medical device OEMs rely on TE’s precision medical device manufacturing and assembly services. We are experts in laser cutting, laser welding, laser ablation and laser marking. TE components and assemblies are used in a variety of medical devices including coronary, peripheral and neurovascular devices, stimulation leads, surgical instruments, dental and orthopedic devices. Good manufacturing practices and tight process controls are applied to all our customers’ applications. No filler materials are added during the laser process, eliminating biocompatibility issues for medical submissions.

Laser Cutting

Precision cutting of materials such as plastic or metal tubing is one of our many strengths. 


Features:

  • Tolerances within 0.0005" or less
  • Kerf width as small as 0.0007"
  • Process small wall thicknesses as thin as 0.002" up to 0.030"
  • Process diameter tubing (i.e. 0.012" x 0.009")
  • Fast, repeatable processes
  • Laser processes cost less than machining or EDM methods


Materials:

  • Stainless steel
  • Nickel
  • Cobalt chromium
  • MP35N


Laser Cutting/Ablation (Polymers):

  • Requires little to no secondary cleaning processes
  • Tolerances within 0.001" or less
  • Drill holes as small as 0.002" or less
  • OD reduction on polymer components and assemblies

Micromachining

Femtosecond laser micromachining is useful for single-step laser processing of multiple materials in medical device applications. Custom designed to be flexible and suitable for on- or off-axis cutting and R&D or volume applications, it can handle both flat stock and tube cutting on the same system with minimal setup. This capability creates new opportunities for advanced micro designs, particularly for difficult-to-process metals, drilling and cutting high-precision holes and shapes free from thermal damage, which are not feasible with conventional lasers.

Advantages of Femtosecond Laser Processing

  • Cuts or drills multiple materials and layers at one time (metal or polymer)
  • Drills and cuts micro shapes
  • OD reduction on metal and polymer components and assemblies (i.e. catheters)
  • Materials and composites including polymers, platinum, stainless steel, nitinol and more
  • Custom designed system for on- or off-axis work
  • Suitable for R&D or volume applications
