What is a common characteristic of the Straight catheter?

The common characteristic of a straight catheter is that it often features sideholes. Sideholes are openings along the length of the catheter that allow for the infusion of fluids or the drainage of bodily fluids. This design enhances the catheter's ability to facilitate flow, especially when positioned within a specific anatomical structure, as it provides additional pathways for fluid delivery or aspiration beyond just the distal end.

While the presence of a sidehole can improve the efficacy of the catheter in various applications, straight catheters are particularly designed for straightforward access and fluid dynamics. The option referencing sideholes emphasizes this functional aspect, underscoring their purpose in optimizing fluid management within the body.

In contrast, options such as the end hole or distal protection device do not typically characterize a straight catheter in the same manner. End holes are more commonly associated with certain types of catheters designed for specific delivery methods, while distal protection devices relate to specialized catheters used in procedures aimed at limiting complications, which do not apply directly to the fundamental design of a standard straight catheter.
