20120178155 | ROTATING CELL SEEDING MODULE - An apparatus and method is described for seeding cells on a sample or specimen. The cells may be selectively and locally seeded on an upper and lower surface of a planar sample or specimen or on either or both of an interior luminal surface and exterior surface of a hollow sample or specimen. The apparatus includes a chamber suitable for cell seeding, cell growth, and cell conditioning. | 07-12-2012 |
20100323438 | GAS AND LIQUID TISSUE CULTURE INTERFACE - An apparatus and method is described for culturing and conditioning cells on a sample. The apparatus includes a fluid delivery system that transmits gas to a first surface of a sample and transmits liquid to an opposite surface of the sample without transmitting liquid onto the first surface. Further, while culturing cells on the sample, the apparatus enables a constant or variable tension and shear stress applied to the sample. The apparatus may thus, for example, be used to culture cells on an external surface of a tissue construct with air and culture cells underneath the tissue construct with a cell growth media. The fluid delivery system may alternatively transmit liquid cell growth media underneath and on the sides of the tissue construct without flowing onto a designated external surface of the tissue construct. In this manner, cells may be cultured on the tissue construct while stretching and relaxing the tissue and further simulating a dissimilar environment on opposite surfaces of the tissue construct. | 12-23-2010 |
20090111180 | BIOREACTOR SYSTEM FOR THREE-DIMENSIONAL TISSUE STIMULATOR - A bioreactor system for growing and conditioning tissue for research and implantation in a human or animal body is disclosed which includes one or more tissue growth chambers for growing and conditioning tissue, each chamber being defined by a housing and providing a fluid culture media cavity which can act as a reservoir. A construct for growing three-dimensional tissues is housed in each tissue growth chamber. Each chamber is connected to a source of pressurized air for applying a controlled pressure to the chamber media cavity. The tissue growth chambers can be mounted on an agitation device such as a shaker system which enhances mass transport within the chamber media cavity. A control system is provided to control the pressure and temperature of the pressurized gas delivered to the chamber media cavity and subsequently to the tissue construct. | 04-30-2009 |
