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 the same. An example of medical devices includes a core member and a tubular member disposed over a portion of the core member. The core member may include an outer diameter region that has an outside diameter that is substantially the same as the inside diameter of the tubular member so that the core member can be attached to the tubular member. The medical device may also include a coil that is coupled to the tubular member.
