How to Use a Guide Catheter?
Guide catheters, as key tools in modern interventional procedures, have expanded their applications far beyond traditional vascular interventions, encompassing a wide range of medical fields, including oncology, neurology, respiratory medicine, and urology. With the continuous advancement of medical technology, the functionality of guide catheters is also constantly improving, helping physicians achieve more precise diagnosis and treatment. Understanding the correct use of guide catheters is crucial for ensuring surgical success and patient safety.
Innovative Design and Advantages of Guide Catheters
Multi-level Design with Different Hardnesses: This design provides guide catheters with increased flexibility, enabling them to more flexibly navigate complex anatomies.
Soft Tip: This significantly minimizes damage to the vessel wall and surrounding tissue, enhancing surgical safety.
Braided Construction: This provides enhanced torque control, stability, and excellent maneuverability, enabling physicians to more precisely deliver the guide catheter to the target location.
Ultra-thin Wall and Large Lumen: This combination enables guide catheters to pass through more complex and larger instruments while maintaining sufficient support.
Low-friction PTFE inner layer: Ensures smooth and rapid passage of guidewires or high-viscosity fluids through the guide catheter, improving surgical efficiency.
Shape retention: Excellent shape retention provides reliable support during prolonged surgical procedures.
Key Steps for Proper Guide Catheter Use
Preparation and Inspection: Before use, carefully inspect the guide catheter packaging for integrity and expiration date, and ensure the model matches the surgical requirements. Also, prepare the guidewire, contrast agent, and other necessary interventional devices.
Access Establishment: Puncture the target vessel (such as the femoral or radial artery) and insert the sheath to establish access for the interventional procedure.
Guidewire Guidance: A guidewire is advanced into the vascular system, serving as a path for the guide catheter.
Guide Catheter Advancement and Positioning: The guide catheter is carefully and steadily advanced along the guidewire to the vicinity of the target lesion or organ. With its excellent torque and maneuverability, physicians can precisely adjust the guide catheter tip, ensuring it remains firmly and stably in the intended position, providing the necessary support.
Diagnosis or Treatment: Once the guide catheter is in place, physicians can deliver complex devices such as microcatheters, balloons, stents, or high-viscosity fluids (such as embolic agents) through its large lumen, allowing for precise diagnostic or therapeutic procedures.
Withdrawal: After the procedure is complete, the guide catheter and sheath are withdrawn smoothly and slowly, ensuring that all interventional devices have been safely withdrawn. Hemostasis is also performed at the puncture site.
