What is the purpose of the white markers on the delivery sheath?

The white markers on the delivery sheath serve the important purpose of indicating when the sheath has reached the delivery of the bevel. This feature is crucial for ensuring precision during the delivery process, as it helps the practitioner determine the optimal point of catheter placement and enhances overall procedural safety and effectiveness. By marking this critical location, the markers assist operators in ensuring that they do not advance the sheath beyond the necessary depth, which could lead to complications.

While identifying the sheath model and depth of insertion are important considerations in clinical settings, the specific function of the white markers in this context is to provide a clear visual cue about the bevel's position during a procedure. Safe handling areas are also essential, but they pertain more broadly to minimizing risk during manipulation rather than signaling a specific step in the insertion process.
