1. Introduction
Endoluminal interventions, procedures conducted within the luminal structures of the body such as blood vessels and gastrointestinal tract, have long been integral to medical practice. Traditional catheters, while effective, often lack the sensitivity and adaptability required for complex procedures. The advent of smart catheters—catheters equipped with real-time, multidirectional pressure sensing—marks a significant advancement in this field. These devices not only monitor physiological parameters but also provide dynamic feedback, enhancing the precision and safety of interventions.
