Abstract
A method for creating a channel through an occlusion located in a substantially elongated body vessel of a patient, The method uses a channel creating apparatus defining an apparatus distal end portion insertable into the body vessel, the channel creating apparatus including an energy delivery component operatively coupled to the apparatus distal end portion for delivering energy substantially adjacent the apparatus distal end portion. The method includes: inserting the apparatus distal end portion into the body vessel; creating a channel first portion through the occlusion harder section using, at least in part, a delivery of energy into the occlusion harder portion; and creating a channel second portion through the occlusion softer portion by pushing the apparatus distal end portion through at least a portion of the occlusion softer portion substantially without delivering energy into the occlusion softer portion.
