Abstract
A catheter for measuring a fractional flow reserve includes a proximal shaft, a distal shaft coupled to a distal portion of the proximal shaft, and a pressure sensor coupled to the distal shaft. The distal shaft includes a middle wall portion configured to extend through a stenosis in a vessel. The middle wall portion of the distal shaft includes at least one skive reducing the cross-sectional profile of the middle wall portion. The middle wall portion may further include at least one stiffening wire for increasing columnar stiffness of the middle wall portion.
