Title
(EN) ENCAPSULATION DEVICE
(FR) DISPOSITIF D'ENCAPSULATION
Abstract
(EN)
Provided herein is a cell encapsulation device comprising an internal chamber suitable for holding biological agents, wherein the internal chamber is disposed between a first semipermeable layer and a second semi-permeable layer, and the first and second semi-permeable layers are mounted on a supporting frame surrounding a perimeter of the internal chamber; wherein the supporting frame comprises a first frame element and a second frame element, and the first and second frame elements co-operate to position the first and second semipermeable layers at a predetermined separation distance between the layers.
(FR)
L'invention concerne un dispositif d'encapsulation de cellule, qui comprend une chambre interne, apte à contenir des agents biologiques, la chambre interne étant disposée entre une première couche semi-perméable et une seconde couche semi-perméable, les première et seconde couches semi-perméables étant montées sur un châssis de support entourant un périmètre de la chambre interne ; le châssis de support comprenant un premier élément de châssis et un second élément de châssis, les premier et second éléments de châssis coopérant pour positionner les première et seconde couches semi-perméables au niveau d'une distance de séparation prédéfinie entre les couches.
