Abstract
A catheter is disclosed for providing a pressure measurement at a vascular lesion. The catheter includes a tubular component having dual lumens along at least a segment thereof in which a first lumen acts as a pressure inlet and a second lumen allows the catheter to be tracked over a guidewire. A plurality of openings are located along a distal segment of the tubular component that permit blood flow into the first lumen when disposed in vivo. A pressure sensor is located within a handle component of the catheter or within the tubular component to be in fluid communication with a proximal end of the first lumen. When the catheter is positioned at the vascular lesion, the first lumen fills with blood via the plurality of openings such that the pressure sensor is able to sense a pressure of the blood at a distal end of the catheter.
