Abstract: A medical device for measuring blood pressure includes a proximal shaft and a distal member including a slotted tube defining a distal lumen extending through the slotted tube, the distal lumen aligned with the proximal lumen and including a distal lumen inner surface. A distal cap is secured to the distal member, the distal cap including a distal cap inner surface defining a void space and an optical pressure sensor is disposed within the void space. A fiber optic cable is coupled to the optical pressure sensor and extends proximally through the distal lumen. A tolerance between an outer surface of the fiber optic cable and the inner surface of the distal lumen inner surface limits relative radial movement of the optical pressure sensor relative to the distal cap inner surface such that the optical pressure sensor is constrained from contacting the distal cap inner surface.

Abstract: Pressure sensing guidewires are disclosed. The pressure sensing guidewires may include a tubular member having a proximal portion and a distal portion. The distal portion may have a plurality of slots formed therein. The distal portion may have a first wall thickness along a first region and a second wall thickness smaller than the first wall thickness along a second region. A pressure sensor may be disposed within the distal portion of the tubular member and housed within the second region. An anti-thrombogenic coating may be disposed on an inner surface, an outer surface, or both of the second region of the distal portion of the tubular member.
