An introducer needle is a specialized medical device used to gain access to the vascular system, typically during procedures that require the insertion of a guidewire or catheter. Here's a detailed overview:

• Design: Usually consists of a sharp stainless steel needle housed in a plastic hub, sometimes with a Y-adapter for ease of guidewire insertion.
• Sizes: Common gauge sizes include 17G, 18G, 20G, and 21G, available in straight or Y-type configurations.
  
  Usage and Safety:
  
• Used By: Qualified medical professionals such as surgeons or interventional radiologists.
• Patient Population: Suitable for all age groups and genders.
• Precautions: Must be used with care to avoid complications like bleeding, hematoma, infection, or vessel perforation.
