  • Pressure distributor and multi-macrocarrier assembly for ballistic transfer transfection apparatus
    Patent number: 5853663
    Abstract: The ballistic transfer transfection technology employs a cold gas shock wave to accelerate microprojectiles that carry matter into cells by mechanical force. The present invention relates to a device that splits the cold gas shock wave into several individual shock waves that spread the pressure of the initial shock wave to several projectile launching devices. The number of cells transfected by this new device is increased manyfold, compared to the original apparatus. The use of the technology in a clinical context is facilitated.
