Abstract
A catheter, such as a fractional flow reserve catheter, includes an elongate shaft having a proximal end optionally coupled to a handle or luer fitting and a distal end having a distal opening. A pressure sensing wire extends to the distal portion of the elongate shaft to be coupled to a pressure sensor mounted on the distal end for measuring a pressure of a fluid within lumen of vessel. The pressure sensor wire is disposed within a pocket formed adjacent to the pressure sensor thereby minimizing the profile of the catheter. Bending or flexing stress or strain experienced by a pressure sensor mounted to a fractional flow reserve catheter when tracking the catheter through the vasculature creates a distortion of the sensor resulting in an incorrect pressure reading or bend error. In order to isolate the sensor from bending or flexing stress and strain, the sensor is mounted so that the sensor is spaced apart from the elongate shaft of the catheter.
