Claim:
1. A venous treatment apparatus comprising: a device comprising an inner sheath and an outer sheath, the outer sheath having a proximal portion, an extended distal portion having a length between 50 cm and 400 cm, and a central portion and the inner sheath substantially fitting within the outer sheath, said central portion of the outer sheath including an expansile braid mechanism having a distal end connected to the extended distal portion of the outer sheath and having a proximal end connected to the proximal portion of the outer sheath, said expansile braid mechanism deployable by axial movement of said inner sheath within said outer sheath so as to engage said central portion against a venous vessel when said venous treatment apparatus is inserted within said venous vessel in a manner that positions said expansile braid mechanism, said expansile braid mechanism being at least partially porous to thrombus and comprising woven strands having one or more of a weave pattern density, strand thickness, adhesiveness, or strand diameter, such that, upon contact with said thrombus, the expansile braid mechanism substantially breaks the thrombus into particles.
