Device and method for removing material from a hollow anatomical structure

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

• a macerator member having a housing adapted for removing material from within the hollow anatomical structure;
• a drive shaft having a proximal end and distal end with the distal end attached to the macerator member;
• and
• an expandable member positioned proximally of the macerator member.

A method for removing material from an anatomical structure comprising:

• inserting clot removal device into an anatomical structure, the clot removal device comprising:
• a macerator member having a housing adapted for removing material from within the hollow anatomical structure;
• a drive shaft having a proximal end and distal end with the distal end attached to the macerator member;
• a rotating wire operably coupled to the distal end of the drive shaft;
• and
• activating the drive shaft to rotate the macerator member and rotating wire to disrupt the material for removal from the anatomical structure.
