Abstract:
The present invention discloses sample thawing devices, systems, and methods, that are configured to take individual 10 mL to 50 mL sample vials and to thaw the contents of such vials. The contents of such relatively large gauge vial are samples with cells, and the thawing of such samples is based on the temperature, volume, and mass of the sample in order to evenly distribute heat and avoid ice crystallization damage to the cells during thawing. A multi-part heater block lined with a thermally-conductive compliant material may be molded to a shape of a vial so as to fittingly mate with known vial sizes. The heater block is capable of separating into three or four segments, providing for ease in inserting and removing samples. The heater block segments can be moved linearly along a tractor, or tilt along a hinge, to move between inward and outward positions.
Abstract:
A system (1000) for use in warming, thawing, cooling, and reconstituting a cryopreserved biological sample (102) is disclosed, which includes a heating system (1100) including a container with an insulating wall defining a chamber to retain a cryogenic fluid (1104), and a receiving space to removably receive a receptacle configured and dimensioned to retain a warming solution (1106). The sample is movable from the cryogenic fluid into the warming solution in an interval of time that results in reduced air exposure and an increased warming rate. A cooling system (1200) is also disclosed for cooling the warmed sample to e.g. room temperature, which includes a repository (1202) that accommodates a series of containers (1204A-1204D) including respective solutions, which achieves simultaneous purging of cryoprotectant from the biological sample, and cooling of the biological sample. A retaining device comprising a tubular member (straw) and a perforated member is also disclosed.
Abstract:
La présente invention concerne un procédé de conservation de cellules, tissus ou organes, de préférence humains, en hypothermie sévère comprenant une étape durant laquelle les cellules, tissus ou organes sont maintenus en hypothermie modérée et de préférence sous atmosphère hypoxique et/ou hypercapnique, avant de les placer en hypothermie sévère.
Abstract:
A method of treating pericardial tissue that includes contacting at least a portion of a pericardial sac with a chemical while the pericardial sac is tensioned by an application of fluid pressure to an inside face of the pericardial sac.
Abstract:
A storage device for a sample of animal tissue and specifically brain tissue. The device has a storage chamber which houses a tissue sample and a control system to control environmental conditions including temperature, oxygenation and/or pH in the chamber. The device also includes an antimicrobial system.
Abstract:
One aspect of the present disclosure relates to a bag for storing blood previously withdrawn from a subject. The bag can comprise a flexible, closed container and at least one removable heat transfer member adhered to an outer surface portion of the container. The container can include an inlet therein that forms part of the container. The inlet can be adapted for fluid-tight connection to a tube member through which the blood is caused to flow.
Abstract:
The present application relates to devices for the vitrification of biological samples, including embryos, oocytes and biological tissues. Suitably, the devices are automated devices which require little if any operator intervention or sample handling, thereby reducing contamination, improving success rates and increasing efficiency. Also provided are methods of vitrifying a biological sample, suitably using the disclosed devices.
Abstract:
A tissue processing system includes a plurality of processing stations. Each processing station includes a plurality of tissue receiving areas that are each configured to accommodate a tissue sample as well as physically isolate that tissue sample from other tissue samples at other receiving areas of the same processing station. Each processing station is configured to separately and individually process the tissue sample at each receiving area to either reduce or eliminate any potential for cross- contamination between the tissue samples undergoing processing at the same processing station. For each receiving area of each processing station, the system is configured to immerse a tissue sample at a particular receiving area in processing fluid for a pre-determined time according to a pre-defined protocol that is based upon parameters of that tissue sample.
