Comparison with Competitor Products
Compared to two-part or cannula-over-needle systems, the one-part needle offers direct feedback and simplicity. Its thinwall construction is a key differentiator, allowing for a larger inner lumen without increasing the outer profile, which is beneficial for patient comfort and procedure efficiency.
Typical User Profile and Application Scenarios
-
Interventional radiologists: Performing angiograms or placing central lines.
-
Vascular surgeons: Establishing access for endovascular procedures.
Best Practices for Use and Maintenance
-
Storage: Store in a cool, dry place away from direct sunlight.
-
Inspection: Verify package integrity before use; do not use if opened or damaged.
