Key summary of medical PI capillary tube

 

 

Precision Medical PI Capillary Tubes Polyimide Material High Insulation

 

 

 

Medical PI (Polyimide) capillary tubes are ​​high-performance medical-grade tubing​​ made from polyimide through precision extrusion and post-processing. They exhibit ​​high temperature resistance (long-term stability up to 350°C and above), excellent biocompatibility, low friction coefficient, and high mechanical strength​​. Their core value lies in meeting the demand for ​​high-precision, high-stability, and low-biological-risk catheters​​ in minimally invasive interventions, neurosurgery, and cardiac procedures, serving as a critical material for ​​domestic substitution of imported products​​.

  3. ​​High insulation performance​​: Dielectric strength ≥300 kV/mm.
  4. ​​Robust mechanical properties​​: Tensile strength ≥150 MPa, elongation ≥10%.
  5. ​​Chemical resistance​​: Medical PI Capillary Tube withstands most solvents except strong acids/alkalis.
  6. ​​Sterilization compatibility​​: Medical PI Capillary Tube survives ethylene oxide, autoclaving, and gamma irradiation.
  7. ​​Strong adhesion​​: Surface-treated for reliable bonding with metals and other materials.

 

 

 

 

 


 

Key applications of medical PI capillary tube

 
 

Medical PI capillary tubes are pivotal in ​​minimally invasive and precision medical fields​​:

 

1. ​​Minimally Invasive Interventional Devices​​

  • ​​Guidewires/Catheters​​: Medical PI capillary tube is used in cardiovascular interventions (e.g., coronary angiography, stent implantation), neurointerventional procedures (e.g., aneurysm embolization), and peripheral vascular interventions. Their high flexibility and kink resistance minimize vascular injury during complex anatomical navigation.
  • ​​Stone Retrieval Baskets​​: In urological surgeries, medical PI capillary tube can ensure stable deployment in ureters/bile ducts for effective stone capture.

 

 

2. ​​Implantable Medical Devices​​

  • ​​Electrode Catheters​​: Serve as carriers in neurosurgery (e.g., epilepsy focus localization) and cardiac electrophysiology (e.g., radiofrequency ablation). Low dielectric constant and high insulation reduce signal interference.
  • ​​Artificial Ligaments/Tendons​​: Combines rigid PI fibers with flexible filaments and nano-silver coatings to promote osteogenesis and tissue repair in orthopedic implants.

 

 

3. ​​Drug Delivery Systems​​

  • ​​Micro-Dose Pump Components​​: High-precision inner diameters (down to 0.05mm) and low friction enable precise dosing of anticancer drugs or insulin, minimizing waste/side effects.
  • ​​Targeted Drug Delivery Catheters​​: Surface-modified (e.g., antibody conjugation) for targeted release in tumors or diseased tissues.

 

 

4. ​​In Vivo Monitoring Devices​​

  • ​​Microfluidic Chips​​: High transparency and corrosion resistance make them ideal for biosensors and cell-analysis chips, enabling real-time monitoring of glucose, blood pressure, or inflammatory markers.

 

 


 

FAQ of medical PI capillary tube

 

 

1. Q: ​​What industries commonly use medical PI capillary tubes?​​

A: Medical PI capillary tubes are widely used in ​​minimally invasive interventional devices​​ (e.g., catheters, guidewires) and ​​implantable medical systems​​ (e.g., neurostimulation electrodes, artificial ligaments) due to their biocompatibility and high thermal stability.

 

 

2. Q: ​​Why are PI capillary tubes preferred in neurosurgical applications?​​

A: PI capillary tubes are ideal for neurosurgical applications like ​​epidural electrocorticography (ECoG) electrodes​​ because of their ​​flexibility, electrical insulation, and long-term stability in harsh physiological environments​​.
