Abstract
A device and method for removing material from inside a tube is provided, comprising a catheter having a tubular body and defining an inner lumen, the distal end portion of the tubular body defining a distal opening and apertures on a sidewall. An expandable member is attached to the distal end portion of the catheter tubular body distal to the one or more apertures. The expandable member is capable of having a first unexpanded condition such that the distal opening is open to allow fluid communication with the inner lumen of the catheter through said distal opening, and a second expanded condition such that the distal opening is occluded to prevent fluid communication with the inner lumen of the catheter through said distal opening, the second expanded condition of the expandable member having a maximum transverse diameter larger than a diameter of the tubular body proximal to the expandable member.
