Guiding Catheter

Guiding catheter

An ultra-thin wall and large lumen let complex devices pass, and multi-durometer design keeps the tip soft while the shaft pushes. The PTFE inner layer lets guidewires and high-viscosity contrast media move smoothly.

Three-layer build

Three layers
Inner layer
Low-friction PTFE liner

Guidewires and high-viscosity contrast media pass without catching. Sections that need bonding are etched to improve adhesion.

Middle layer
304SS braid

Carries torque transmission and shape retention. Carrier count and braid angle are tuned to the stiffness you need.

Outer layer
Multi-durometer design

Stiff proximally, soft distally, divided by segment. The tip is formed as a soft tip that reduces vessel trauma.

FAQ

FAQ
How do Fr markings map to actual outer diameter?

Standard outer diameters are 5F 1.80 mm, 6F 2.10 mm, 7F 2.40 mm and 8F 2.65 mm. Inner diameter varies with the wall build even at the same Fr.

Are curves outside the list possible?

Yes. Send a drawing or a physical sample and we come back on mold feasibility and schedule.

Can I buy the shaft only?

Yes. We supply the shaft on its own, or as a finished device assembled with hub and strain relief.

How far do you go on sterilization and packaging?

We handle EO sterilization and individual packaging. Tell us the specification you need with your inquiry.

Size (Fr), curve, working length. Those three are enough to start. A drawing makes it faster.
