Abstract
Systems and methods are provided for removal of clot material from a treatment site in a blood vessel, particularly in venous vasculature. A treatment device () can include a core member () having a distal portion () and an inner coil () surrounding the distal portion of the core member. A helical outer member () surrounds at least a portion of the inner coil, and a sheet of flexible material () extends between the inner coil and the helical outer member, such that the sheet extends helically around the inner coil to provide a surface for clot engagement at the treatment site.
