  • Lumen based pressure sensing guidewire system with distortion correction
    Patent number: 9247909
    Abstract: A guidewire is disclosed that is constructed using tubular members that create a hollow lumen that runs from the proximal end of the guidewire to a window towards the distal end of the wire. This internal lumen is filled with a fluid that allows pressure exerted at the window to exert pressure at the proximal end of the guide wire proportional to the pressure exerted at the window. This pressure exerted at the proximal end of the guidewire is measured using a pressure transducer external of the guidewire. The pressure transducer converts the measured pressure into an electrical signal that is proportional to the pressure at the window. The electrical signal is manipulated to correct for errors that are due to the pressure signal traveling though the inner lumen of the guidewire to ensure the electrical signal matches the pressure exerted at the window.
