Title
(EN) METHODS AND SYSTEMS FOR ENCAPSULATION DEVICES FOR HOUSING CELLS AND AGENTS
(FR) PROCÉDÉS ET SYSTÈMES POUR DISPOSITIFS D'ENCAPSULATION SERVANT À ENVELOPPER DES CELLULES ET DES AGENTS
Abstract
(EN) Encapsulation devices, systems and methods are provided. In some embodiments, encapsulation devices for housing cells and providing various therapeutic benefits to a patient or host are provided. Encapsulation devices are provided that include a matrix or scaffold within a cell-receiving area or void, and methods of forming and preparing such a matrix are disclosed. Encapsulation devices that include channels are further provided, and the channels of the present disclosure are operable to convey fluid to internal areas of devices without restricting vascularization.
(FR) La présente invention concerne des dispositifs d’encapsulation, des systèmes et des procédés. Selon certains modes de réalisation, l'invention concerne des dispositifs d'encapsulation servant à envelopper des cellules et à offrir divers bienfaits thérapeutiques à un patient ou à un hôte. L'invention concerne des dispositifs d'encapsulation qui comprennent une matrice ou un échafaudage à l'intérieur d'un vide ou d'une zone de réception de cellules, et des procédés de formation et de préparation d'une telle matrice. L'invention concerne en outre des dispositifs d'encapsulation qui comprennent des canaux, et les canaux de la présente divulgation peuvent être utilisés pour transporter un liquide vers des zones internes de dispositifs sans restreindre la vascularisation.
