20120065047 | Centrifuge and separation vessel therefore - The centrifugation vessel includes an outer wall containing an interior space. A dam defines a barrier which divides the interior space into at least two regions including a catch basin defining a higher gee region and a reservoir defining a lower gee region. These regions are joined together over the dam. The dam includes a face which is preferably tapered to enable optimization of speed of separation of a sample placed within the vessel. The vessel is usable in a biological sample processing method by having the higher gee region of the vessel configured to have an elongate form and the volume optimized for collection of a higher density fraction of the sample. Supply and withdrawal tubes extend into the regions for reliable extraction and separate collection of differing density fractions after separation by centrifugation. | 03-15-2012 |

20120171762 | Stem and progenitor cell compositions recovered from bone marrow or cord blood; system and method for preparation thereof - The invention includes compositions of stem and progenitor cells recovered from bone marrow or cord blood containing most of the viable CD34+ cells and substantially depleted of red blood cells resident in the original sample, without any xenobiotic additives to aid cell separation. The invention also includes a system and method for preparing the compositions. The system includes a bag set and a processing device, which utilizes an optical sensor, microcontroller, servo motor, accelerometer, load cell, and battery. The system and method utilize centrifugation to stratify the cells into layers and then separate and transfer the stem cells into a stem cell bag. The processing device's microcontroller receives input from the device's accelerometer, load cell and optical sensor to direct the metering valve in the bag set to open and close to permit the transfer of as many stems cells as possible with as few red cells as possible. | 07-05-2012 |

20120213754 | Method of Preconditioning of Cell Suspensions - An apparatus for the preparation of cells for implantation into a living body is disclosed. The apparatus comprises a vessel substantially impermeable to gaseous oxygen; and fluid within said vessel, the fluid having a maximal dissolved oxygen capacity substantially equivalent to normal saline yet having a hypoxic oxygen concentration between about 0% to about 5% of said maximal dissolved oxygen capacity. The bag oxygen concentration level remains low when the apparatus is stored at 22°-25° C. in normal atmospheric conditions for a period of at least 30 days. The present invention simplifies the process of achieving donor cell hypoxic preconditioning for cell implantation, and may be used to bathe said cells to be transplanted for a sufficient time to activate the hypoxic metabolic pathway. | 08-23-2012 |
