What is the primary purpose of End Hole catheters in interventional procedures?

The primary purpose of end hole catheters in interventional procedures is to access the vascular system. End hole catheters are specifically designed with an opening at the end, allowing for the introduction of contrast media, fluid, or other substances directly into the vascular system or to facilitate the exchange of guidewires and other instruments. This direct access is essential for various interventional techniques, such as angiography, catheter placements, and other diagnostic or therapeutic procedures.

In addition to their access function, end hole catheters may also be used in different configurations to optimize fluid flow, but their fundamental role remains centered on providing a means to reach the internal vasculature efficiently. The design also helps navigate through blood vessels while minimizing trauma to the surrounding tissues.
