Method and apparatus for the oxygenation of the blood. The apparatus (14) includes a hollow membrane (16) having a central tubular portion (32) and a plurality of radially outwardly extending diffusion elements (34). The membrane is disposed within a sheath (18) and both are supported by a flexible wire (20), one end of the membrane and sheath being secured to the wire. The other end of the membrane and sheath are secured to a tube (22) through which oxygen may be supplied to the hollow membrane. The sheath and membrane may be twisted upon the wire (20) to facilitate insertion and, once inserted, they may be untwisted to resume their operable position.
