  • Selective access to cryopreserved samples
    Patent number: 9296500
    Abstract: Methods and apparatus for selectively accessing a portion of a sterile cryopreserved sample are disclosed. The apparatus may include a container configured to receive the cryopreserved sample and having a first portion and a second portion, a heat sink chamber surrounding the first portion of the container, and a heat source adjacent to the second portion of the container. The chamber may be configured to maintain a non-accessed portion of the sample in a cryopreserved state. The heat source may be configured to separating an accessed portion of the sample from the non-accessed portion of the sample while maintaining the viability of the accessed portion while the non-accessed portion is maintained in the cryopreserved state.
    Type: Grant

  • Apheresis methods and devices
    Publication number: 20050143684
    Abstract: An apheresis method that includes drawing blood from a mammal, adding an amount of an agent effective in preventing coagulation, wherein the agent is an anticoagulant, extracting one or more constituent components from the blood, wherein an extracted blood and constituent component result therefrom, and diminishing the activity of said anticoagulant by introducing an antidote, wherein the amount of antidote introduced is coupled with the amount of anticoagulant added. The antidote is provided either to the processed blood prior to reintroduction to the donor or directly to the donor. The invention also includes an apheresis machine that includes an antidote delivery conduit, wherein the antidote delivery conduit delivers an amount of antidote that is coupled with an amount of anticoagulant delivered.
