    摘要: Devices and methods are provided for reducing the lateral displacement of an endovascular device, e.g. a stent graft, within an aneurysm sac. A stabilization system comprising one or more stabilizing elements is inserted within the aneurysm space between an implanted device and the vessel wall. Filling this space prevents changes in curvature of the implanted endovascular device, and prevents longitudinal displacement, thereby providing for improved long-term stability and durability of endovascular repair.

    摘要: Methods and apparatus are provided for culturing cells under conditions for determining cellular differentiation and for separating cells from culture media based on differentiation. The apparatus comprises a bioreactor, media reservoir, a magnetic cell separator, an inlet port for adding magnetic particles to the bioreactor, and a circulating pump, wherein the bioreactor, media reservoir, magnetic cell separator and inlet port are on a single fluid circuit. The present method and apparatus provides a method for separating cells from culture without removing the cells from culture, so that un-selected cells may be returned to the bioreactor for further culture. The method employs magnetic labeling in culture, where the magnetic label specifically identifies cells to be distinguished, either by separation or retention in the culture. The method and apparatus are further designed to comprise means for electromechanical stimulation of hum embryonic stem cells for preparation of electrically responsive tissue.
