Abstract
A medical device, such as a guidewire, catheter, or the like, that includes an elongated tubular member that includes a plurality of angled slots defined in at least a distal section thereof. The plurality of angled slots can form a generally spiral shaped pattern about the longitudinal axis of the tubular member, and can be useful, for example, in aiding a user of the device in crossing an occlusion in a vessel of a patient. In some embodiments, the distal section of the tubular member may have an outer diameter that is greater than the outer diameter of a proximal section of the tubular member. In some embodiments, a proximal section of the tubular member may include a plurality of slots defined therein, for example, that may be configured to increase the lateral flexibility of the tubular member.
