Abstract
A vascular lining removal assembly comprises a plurality of slats, each having inner and outer surfaces, configured to pass along a vascular cleavage plane to removingly engage a length of vascular lining. In some embodiments the assembly may also include means for engaging the length of vascular lining to aid removal of the length of vascular lining. The inner surface of at least one of the slats may comprise an inwardly opening passageway to permit direct access to the length of vascular lining by a tool.
