PTFE Guidewire
Product Features
● PTFE Guidewire has good flexibility and is not easy to bend.
● The PTFE coating layer is good lubricity, easy to insert smoothly.
● For cardiovascular surgery and urinary surgery.
● Guide angiography catheter in cardiovascular surgery.
● Made from materials like stainless steel, providing strength and flexibility.
● Includes radiopaque tips or markers for visibility under fluoroscopy or X-ray imaging.
Material and structure
● Stainless steel core wire + Stainless steel spring wire+ PTFE coating(coating on spring wire)
Instruction for use
Pre-Procedure Preparation
● Wire Selection: Choose an appropriate diameter and length.
● Inspection: Ensure sterile packaging is intact. Check for defects (kinks, coating peeling).
● Flushing: Flush with heparinized saline to lubricate and prevent clotting.
Insertion & Navigation
● Vessel Access: Use the Seldinger technique to insert a sheath (e.g., femoral, radial).
● Wire Introduction: Advance the PTFE wire through the sheath under fluoroscopic guidance. Rotate gently for better steerability in tortuous anatomy.
Catheter Guidance
● Once the wire is positioned in the target vessel, advance the angiography catheter over it. Maintain wire position while injecting contrast.
Lesion Crossing (if needed)
● For tight stenoses, use slow, controlled movements to avoid dissection.
Contrast Injection & Imaging
● Retract the wire slightly before contrast injection to avoid artifactual vessel narrowing.
● Re-advance the wire if further catheter manipulation is needed.
Post-Angiography Steps
● Wire Removal: Withdraw slowly under fluoroscopy to ensure no vessel injury.
PRODUCT APPLICATION
● Vascular Interventions: Used in angioplasty, stent placement, and other vascular procedures.
● Urological Procedures: Navigates through the urinary tract for stone removal or stent placement.
● Biliary and Pancreatic Interventions: Assists in accessing and treating blockages in the bile or pancreatic ducts.
● Gastrointestinal Procedures: Used in endoscopic retrograde cholangiopancreatography (ERCP) or other GI interventions.
● Neurological Interventions: Supports navigation in neurovascular procedures.
