Which of the following is NOT a characteristic of the Cobra catheter?

The Cobra catheter is primarily recognized for its unique characteristics that enhance its performance in vascular access and procedures. Its design allows for easy navigation through the vascular system, particularly when accessing the visceral arteries.

Considering the characteristics outlined, the end hole design is significant because it facilitates efficient contrast flow during angiographic procedures. The angled configuration is also essential, as it aids in steering the catheter into the optimal position within the vascular anatomy. These features collectively contribute to its effectiveness in various interventional radiology procedures.

However, the Cobra catheter is not characterized by side holes. Unlike other catheter designs that incorporate multiple side holes to allow for lateral drainage or distribution of fluids, the Cobra catheter operates predominantly through its end hole, which is designed to minimize turbulence and provide a streamlined passage for contrast media. Therefore, identifying the absence of side holes as a characteristic sets this option apart from the others that are inherent to the Cobra catheter's design and function.
