Torque Tester for Guidewires and Catheters
Precision Instrument for Testing Torsional Strength, Constant Torque, and Angle Performance of Intravascular Devices
ToronMed™ TTGC04 Torque Tester is engineered for the determination of torque to failure, constant torque, and constant angle performance at the critical welding or joint points of intravascular guidewires, catheters, and related tubular devices. With its millinewton-level precision, the system is ideal for both R&D and quality assurance applications.
The tester is equipped with advanced torque sensors, flexible fixture systems, and professional PC software for real-time torque monitoring, curve analysis, and automatic data logging, making it compliant with modern testing standards for interventional medical devices.
Special Capabilities
- Ideal for low-torque testing applications, including micro guidewires and fragile catheter joints
- Software-controlled test modes:
- Constant torque
- Constant angle
- Torque to failure (torsional strength)
- Tests both rotational stiffness and yield point of catheter and guidewire assemblies
- Suitable for single-use and multiple-use catheter technologies
Applications
Primary Use Cases | Extended Use Cases |
|---|---|
| Intravascular Guidelines | Other medical tubing |
| Interventional Catheters | Bars and tubular components |
| Welded Joint Evaluation | Flexible or coiled shafts |
Test Principle
The sample is clamped onto a fixed mounting plate. Torque is applied and measured via a sensitive inline torque sensor. The system captures torque data in real time, enabling analysis of failure points, angle of twist, and constant torque behavior under dynamic or static loading conditions.
