Does polyimide tubing have flexibility?
In the fields of medical device manufacturing, minimally invasive interventional therapy, and high-precision engineering, polyimide tubing has received widespread attention due to its excellent comprehensive performance. With the continuous upgrading of minimally invasive technology, the application of medical polyimide tubing in clinical fields such as vascular intervention, electrophysiology, urology, and structural cardiology is becoming increasingly prominent.
How flexible is polyimide tubing?
The answer is very clear: polyimide tubing has excellent flexibility and maintains stable performance over a very wide temperature range.
Thanks to the molecular structure of polyimide material, it possesses excellent bending properties while maintaining high strength and high temperature resistance. Whether bent at room temperature or during dynamic movement, polyimide tubing is not easily broken, deformed, or fatigue-induced, making it particularly suitable for components in medical devices that require repeated bending.
Typical Applications of Polyimide Tubing in the Medical Field
Due to its high mechanical strength, excellent flexibility, and good dimensional stability, medical polyimide tubing has achieved mature applications in multiple clinical fields, including:
Vascular Intervention: Used in vascular stent delivery systems, guidewire sheaths, etc.
Structural Cardiac Devices: Used in high-precision delivery components and protective cannulas.
Electrophysiology: Used in miniature tubing for mapping and ablation of flexible shafts.
Urology: Such as stone retrieval basket catheters, ureteroscope-related accessories.
Endoscopy: Used in endoscopic catheters, flexible manipulation tubing, etc.
These applications place extremely high demands on the material's flexibility, fatigue resistance, dimensional accuracy, and biocompatibility, and polyimide tubing demonstrates its core advantages in these aspects.
Why is medical polyimide tubing so popular?
Combined Flexibility and High Strength
It can withstand repeated bending and torsion in narrow spaces, which is especially crucial for vascular and urinary system devices.
High Temperature and Radiation Sterilization Resistance
Compatible with mainstream medical sterilization processes, such as high-temperature steam sterilization, ethylene oxide sterilization, or gamma ray sterilization.
Excellent Dimensional Stability
Maintains extremely high inner diameter accuracy and wall thickness consistency, suitable for the high-precision production of minimally invasive medical devices.
Good Biocompatibility
Meets the material requirements for medical devices and can be used in disposable or short-term contact products.
Multiple Applications Validate the Strength of Polyimide Tubing
Besides the medical industry, polyimide tubing is widely used in aerospace, industrial automation, fiber optic protection, and sensor components, further demonstrating its comprehensive advantages in flexibility, temperature resistance, mechanical strength, and chemical stability.
