摘要： Threads hollow (2) in length serve as filters for removing waste or noxious materials in the blood, and are gathered to make fluxes. The fluxes are closed at end portions of the threads, filled with liquid into the hollow parts and are set in a housing (1). The housing is applied with fixing agent (3) at its end portions, and effected with centrifugal force, so that the ends of the hollow threads are made suitable shapes for moving the liquid.

摘要： The invention provides an apparatus for plasma separation which is designed so that during the process of separating blood into plasma and corpuscular components by means of plasma separation membranes (10), if the rate of plasma permeation through the membranes (10) is decreased so that the trans-membrane pressure differential exceeds a predetermined value, the number of revolutions of a plasma pump (4) is adjusted downward to permit restoration of a trans-membrane pressure differential lower than the predetermined value. The rate of plasma discharge is gradually decreased according to the varying permeability of the membranes (10) to plasma, whereby a most effective performance of the membranes (10) can be assured. The apparatus can be used for carrying out various blood treatment methods wherein blood is separated into plasma and corpuscular fractions to remove the plasma containing pathogenic factors or to remove the pathogenic factors from the plasma.

摘要： Provided is an intravascular placement tool and an intravascular placement system that, when connecting and using multiple intravascular placement tools, enable smooth transport of an intravascular placement tool that is placed later. An intravascular placement tool (stent graft 1) is placed in a first blood vessel (main blood vessel V1) where a second blood vessel (branched blood vessel V2) branches. The intravascular placement tool (1) includes: a tubular placement tool body (graft body 10); and a branching portion (20) that is protrudingly provided on the placement tool body (10) and that can be connected with another intravascular placement tool (second stent graft 2) placed in the second blood vessel (V2). The relative arrangement between the placement tool body (10) and the branching portion (20) is defined on the basis of the relative positional relationship between the first blood vessel (V1) and the second blood vessel (V2).
