Abstract
A hemodialysis catheter with a plurality of umbrella-like wire members covered with a film which works as a thrombus blocker and can easily and effectively remove the thrombus is disclosed. The hemodialysis catheter has a proximal lumen, the arterial lumen, and a distal lumen, the venous lumen. An elongate member is longitudinally put in either the proximal lumen or the distal lumen, or two elongate members in both lumens. A plurality of umbrella-like wire members are connected to the end of the elongate member. When the hemodialysis catheter is put in the vessel but not in use, the end of the lumen is capped off by the plurality of umbrella-like wire members covered with a film. When it is ready to use, the doctor can pull the elongate member which connects to the plurality of umbrella-like wire members out off the lumen inverting the plurality of umbrella-like wire members and clearing away any thrombus that has formed.
