Abstract
(EN) A perfusion bioreactor and a perfusion device. Each perfusion device has a mesh structure, and an encapsulated organ tissue (EOT) disposed in the mesh structure. The EOT has a body with a thickness defined between a first surface of the body and a second surface of the body. The body has at least one channel extending into the body from one of the first and second surfaces to receive a fluid therein. The at least one channel has a diameter selected to diffuse solutes out of the fluid and into the body. The perfusion devices are arranged one adjacent to another and spaced apart from each other along the length of the bioreactor to receive fluid, and to perfuse the fluid to the EOT of each perfusion device and to the at least one channel therein. A method of processing blood plasma and an artificial liver system are also disclosed.
(FR) L'invention concerne un bioréacteur de perfusion et un dispositif de perfusion. Chaque dispositif de perfusion possède une structure maillée et un tissu organique encapsulé (TOE) disposé dans la structure maillée. Le TOE possède un corps pourvu d'une épaisseur définie entre une première surface du corps et une seconde surface du corps. Le corps possède au moins un canal s'étendant dans le corps à partir de l'une parmi la première et la deuxième surface, pour recevoir un fluide en son sein. Ledit au moins un canal possède un diamètre sélectionné pour diffuser des solutés hors du fluide et dans le corps. Les dispositifs de perfusion sont agencés les uns à côté des autres et écartés les uns des autres le long de la longueur du bioréacteur pour recevoir un fluide et pour perfuser le fluide dans le TOE de chaque dispositif de perfusion et dans ledit au moins un canal en son sein. L'invention concerne également un procédé de traitement de plasma sanguin et un système de foie artificiel.
