摘要： Medical devices and methods for making and using the same are disclosed. An example medical device may include a guidewire. The guidewire may include a core wire having a distal portion. A tubular member may be disposed over the distal portion. The tubular member may have a plurality of slots formed therein and may have a longitudinal axis. The tubular member may include a variably spaced slot section that has a flexural rigidity that varies from a first flexural rigidity to a second flexural rigidity. The transition from the first flexural rigidity to the second flexural rigidity may be a function of a fourth power equation. The first flexural rigidity may be in the range of about 1×10−6 to about 9×10−5 lbs-inches2. The second flexural rigidity may be in the range of about 1×10−3 to about 5×10−3 lbs-inches2.

摘要： Medical devices and methods for making and using medical devices are disclosed. An example medical device includes a pressure sensing guidewire. The pressure sensing guidewire may include an elongate shaft including a core wire having a distal portion and a coil disposed over the distal portion. A pressure sensor may be disposed along the distal portion of the core wire and within the coil. One or more leads may be coupled to the pressure sensor. An opening may be formed in the coil that provides access to the pressure sensor.
