Catheters & Guidewires

Precision Platinum and Tungsten Materials for Minimally Invasive Devices

Designing interventional devices requires balancing multiple performance requirements simultaneously. Guidewires and catheter components must provide flexibility for navigating complex anatomy while maintaining sufficient stiffness, torque transmission, corrosion resistance, and radiopacity for precise visualization during minimally invasive procedures.

Material selection plays a critical role in achieving that balance.

Sigmund Cohn Corp. manufactures precision platinum, platinum-iridium, tungsten, and specialty alloy wire, tubing, ribbon, coils, and marker components engineered specifically for interventional medical applications. Our platinum and platinum-iridium alloys provide exceptional biocompatibility, corrosion resistance, and radiopacity, while tungsten offers superior density and visibility for marker bands and other radiopaque components. Together, these materials enable engineers to optimize device performance for specific clinical applications.

Our precision manufacturing processes ensure consistent dimensions, superior surface quality, and repeatable mechanical performance required for today's advanced minimally invasive medical devices.
