    • Extracorporeal cell-based therapeutic devices and delivery systems are disclosed which provide a method for therapeutic delivery of biologically active molecules produced by living cells in response to a dynamic physiologic environment. One embodiment includes long hollow fibers in which a layer of cells are grown within the intraluminal volume or within a double hollow-filled chamber. Another embodiment includes a wafer or a series of wafers providing a substrate onto which cells are grown. The wafer(s) are inserted into a device. A device may deliver a pre-selected molecule, for example, a hormone, into a mammal's systemic circulation and/or may deliver a member of different cell products. The device is adapted to secure viable cells which produce and secrete the pre-selected molecule into blood or fluid. The invention also provides a minimally invasive method for percutaneously introducing into a preselected blood vessel or body cavity the device of the invention.
    • 公开了基于体外细胞的治疗装置和递送系统,其提供了响应于动态生理环境而由活细胞产生的生物活性分子的治疗递送的方法。 一个实施方案包括长的中空纤维,其中细胞层在腔内体积内生长或在双重中空填充的室内生长。 另一个实施例包括晶片或一系列晶片,其提供生长细胞的衬底。 将晶片插入设备中。 装置可以将预先选择的分子例如激素递送到哺乳动物的体循环中和/或可以递送不同细胞产物的成员。 该装置适于将产生和分泌预先选择的分子的活细胞固定到血液或流体中。 本发明还提供了一种微创方法,用于将本发明的装置经皮引入预选的血管或体腔。

    • An improved extracorporeal liver assist device (10) and method is provided which employs a blood perfusion membrane (12) cultured with initially transformed hepatocytes until a confluent monolayer is developed, whereupon the hepatocytes are reverted to the somatic phenotype for perfusion purposes. Use of transformed hepatocytes permits serial subculturing to maintain a clinical supply of cells for the patient, while the in vitro proliferation characteristics and loss of contact inhibition of the transformed hepatocytes ensure rapid cell division and layer formation on the perfusion membranes. Virally transformed, temperature sensitive hepatocytes are preferred so that reversion of the cells can be accomplished by temperature change. The transformed hepatocytes may be cultured on the exterior surfaces of multiple capillary membrane cartridges (50), and subsequently reverted by elevating the temperature thereof.
    • 提供了一种改进的体外肝辅助装置(10)和方法,其采用与初始转化的肝细胞培养的血液灌注膜(12),直到融合的单层形成,由此肝细胞被还原成体细胞表型用于灌注目的。 转化肝细胞的使用允许连续传代培养以维持患者的细胞的临床供应,而转化的肝细胞的体外增殖特征和接触抑制的丧失确保灌注膜上快速的细胞分裂和层形成。 病毒转化,温度敏感的肝细胞是优选的,以便可以通过温度变化来实现细胞的逆转。 转化的肝细胞可以在多个毛细管膜盒(50)的外表面上培养,随后通过升高其温度而恢复。
