Abstract
A fluid pressure monitoring system for a balloon catheter includes a pressure transducer in fluid communication with the interior of the balloon. The pressure transducer includes elements for providing an electrical signal which is a function of the pressure in the interior of the balloon. An electronic digital display is responsive to the electrical signal from the pressure transducer to display the balloon pressure measured by the pressure transducer. The system is especially suited for coronary angioplasty in which a catheter is inserted through blood vessels in the human body to the vicinity of a stenosis. The catheter carries an inflatable balloon to the vicinity of the stenosis, where it is inflated, and the fluid pressure monitoring system of the present invention detects and digitally displays to the cardiologist the pressure inside the inflated balloon.
