    • An accessing assembly for hemodialysis administration, having an intravascular tube assembly, a conduit assembly, first and second catheter sleeve assemblies, and first and second catheter assemblies. The intravascular tube assembly has an intravascular tube, a subcutaneous cuff, a tube end and a ring with a hole. The conduit assembly has first and second conduits having respective conduit threading. The first and second catheter sleeve assemblies have collapsible sidewalls, ends, and joining ends respectively. The collapsible sidewalls define cavities respectively, and couplers are defined within the cavities. The first and second catheter assemblies have catheter sidewalls, inlet/outlet ends, internal ends, and fasteners respectively. The catheter sidewalls have a plurality of holes. The intravascular tube is implanted within a vascular structure. The catheter sidewalls are positioned inside to respective collapsible sidewalls. The collapsible sidewalls are collapsed until respective fasteners are threaded onto respective couplers.
