    摘要: Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a guide extension catheter. The guide extension catheter may include a proximal tubular member having a lumen defined therein. A distal tubular member may be attached to the proximal tubular member. The proximal tubular member may have an outer diameter. The distal tubular member may have an inner diameter. The inner diameter of the distal tubular member may be greater than the outer diameter of the proximal tubular member. A stiffening member may be slidably disposed within the proximal tubular member.

    摘要: 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.
