  • Publication number: 20190217063
    Abstract: Medical devices and methods for making and using medical devices are disclosed. An example medical device may include an elongate shaft having a proximal end region and a distal end region. A first lumen may be defined in the shaft. A second lumen may be defined in the shaft. The distal end region may include a common lumen region in fluid communication with the first lumen and the second lumen. A deflectable member may be disposed within the shaft. The deflectable member may be designed to shift between a first configuration where the deflectable member directs a first medical device disposed within the common lumen region into the first lumen and a second configuration where the deflectable member allows a second medical device to move between the common lumen region and the second lumen.

  • Publication number: 20170055908
    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.
