Apparatus for therapeutic apheresis
First Claim
1. Apparatus for carrying out therapeutic apheresis comprising:
- an implantable filter device comprising one or more elongated hollow tubes and a plurality of elongated microporous fibers capable of separating plasma from whole blood in-vivo, each fiber having an interior lumen extending along the length thereof and having a first and second end secured to one or more of said elongated hollow tubes wherein the interior lumen of each of the fibers communicates with the interior of one or more of the hollow tubes;
a triple lumen catheter secured to the proximal end of the filter device having one or more lumens in fluid communication with the interior of said one or more hollow tubes and a plasma return lumen; and
therapeutic apheresis apparatus for removing and/or separating selected disease-related components from the separated plasma and tubing for directing plasma between said catheter and the selective component removal apparatus.
