A device for being implanted in a blood vessel for carrying out continuous in vivo plasma separation comprises an elongated, axial header and at least one elongated microporous fiber having a hollow interior, said fiber being dimensioned to be received within a blood vessel without significantly obstructing fluid flow through said blood vessel, the pore size of said fiber being sufficient to allow plasma to diffuse through said pores into said hollow interior of said fiber but not sufficient to allow cellular components larger than plasma to diffuse therethrough, said one or more fibers extending laterally relative to the axis of said header and in fluid communication with said header.

In another embodiment, the fibers comprise a drogue-shaped device comprising a plurality of said fibers aligned lengthwise, a first end of said fibers terminating substantially in first plane and generally forming an annulus having a first diameter, and a second end of said fibers terminating generally in a second plane and secured in an annular header having a second diameter smaller than said first diameter.
