1. The manufacturing process is complicated: the pressure microcatheter needs to be manufactured by fine micro-nano processing technology and requires high-precision equipment and instruments, so its manufacturing cost is relatively high.
2. Excellent materials: Because pressure microcatheters are usually used to measure high-precision pressure and need good mechanical strength, thermal stability, corrosion resistance and other characteristics, it is necessary to use high-quality materials, such as stainless steel, which makes the cost relatively high.
The price of pressure microcatheter is relatively high, but its high precision and high quality make it widely used in many high-end applications.
