摘要：
A method for removing material within a body lumen of a patient is disclosed. The method include introducing a distal end of a tubular member into a body lumen. The tubular member has a guide member extending distally from the distal end. Next, the tubular member is positioned such that the distal end is disposed adjacent material to be removed and a distal tip of the guide member is disposed beyond the material. One or more lumen clearing elements are then deployed from the distal tip of the guide member. Each lumen clearing element includes an expandable structure that expands from a contracted condition within the guide member to an expanded condition when deployed from the distal tip. Then, the deployed one or more lumen clearing elements are retracted along a track of the guide member to engage the material disposed adjacent the distal end of the tubular member and draw the material into a lumen of the tubular member.
