Commonly Welded
Components

Marker Bands

Laser welding radiopaque marker bands onto a hypotube is the best way to accurately and strongly secure them to the catheter shaft. This process ensures each band is positioned with exceptional precision and strength, without adhesives or excess heat

Pull
Wires

Precision laser welding ensures a durable, low-profile bond between pull wires and hypotubes — critical for consistent control in steerable catheter assemblies. Our process delivers superior weld strength with minimal thermal distortion, ideal for fine medical components.

Micro
Joints

Laser welding is the strongest choice for joining small metal components across medical assemblies — from the distal tip to the handle. It delivers clean, repeatable joints with minimal heat effects, ensuring both structural integrity and biocompatibility in even the most intricate device designs.
