Packaging of a MEMS sensor in an active interventional blood pressure monitoring catheter

In the field of interventional pressure monitoring catheter, common types of catheters mainly include invasive arterial pressure catheter, central venous pressure catheter, pulmonary artery floating catheter, etc. A common way to measure intravascular pressure with such catheters is to direct arterial or venous blood to a pressure sensor outside the body through a hole in the distal end of the cat...
