Claim Text:
1. A method for crossing an occlusion in a vessel lumen of a patient, the method comprising: inserting a medical device into the vessel, the medical device including an elongated tubular member extending along a longitudinal axis and defining an inner lumen and having an outer surface, the elongated tubular member including a proximal section, a distal section, a proximal end, and a distal end, the distal section including a plurality of angled discontinuous slots disposed non-normal to the longitudinal axis defined therein, wherein the plurality of angled discontinuous slots form a generally spiral shaped pattern about the longitudinal axis, the spiral shaped pattern defined by the plurality of angled discontinuous slots generally defining one or more generally spiral shaped structures remaining as a part of the distal section of the elongated tubular member, the distal section having an outer diameter that is greater than an outer diameter of the proximal section; wherein the elongated tubular member includes a distal tip member attached at the distal end such that the inner lumen has a closed distal end; navigating the medical device to the occlusion such that the distal end of the elongated tubular member engages the occlusion; applying a rotational force to the medical device such that the one or more spiral shaped structures or the plurality of angled discontinuous slots engages the occlusion and pulls at least a portion of the medical device through the occlusion.
