Device and method for removing material from a hollow anatomical structure

A method for removing material from a hollow anatomical structure, comprising:

• inserting a removal device including a radially expandable capture member, a treatment segment having at least one exit port and an embolic capture device having a radially expandable filter;
• positioning the treatment segment near the material such that the expanded filter is positioned distally of the treatment segment and the expanded capture member is positioned proximally of the treatment segment, the expanded filter capable of capturing a part of the material which travels downstream of the treatment segment;
• injecting a fluid agent to the material through the exit port;
• receiving the treatment segment in the expanded capture member;
• and
• receiving the embolic capture device in the expanded capture member.
