Wei Y. Kuu has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9279615
    Abstract: This application discloses devices, articles, and methods useful for producing lyophilized cakes of solutes. The devices and articles provide for a method of freezing liquid solutions of the solute by the top and the bottom of the solution simultaneously. The as frozen solution then provides a lyophilized cake of the solutes with large and uniform pores.
    Type: Grant

  • Patent number: 8544183
    Abstract: A device for supporting at least one vessel containing a target material to be lyophilized generally includes a support panel, a central region, a perimeter region, a thermal shield, and at least one shielding cavity. The support panel has a support surface. The central region is defined by the support panel for supporting the at least one vessel. The perimeter region is also defined by the support panel and surrounding the central region. The thermal shield is positioned about the perimeter region and extends transverse to the support surface of the support panel such that the thermal shield and the support panel define a storage space for accommodating the at least one vessel. The at least one shielding cavity is defined by the thermal shield and contains a shielding material during a lyophilization process. The shielding material is distinct from the target material.

  • Publication number: 20110155620
    Abstract: A method of preparing and reconstituting a sterile, lyophilized pharmaceutical active for rapid reconstitution by evacuating a lyophilized pharmaceutical active-containing container until the pressure within the container is less than about 300 Torr and hermetically sealing the evacuated container. The sterile, lyophilized pharmaceutical active can be prepared by flash freezing a pharmaceutical active-containing composition then lyophilizing the composition. The hermetically sealed lyophilized pharmaceutical active can be reconstituted by adding at least the total volume of liquid necessary for reconstitution of the sterile, lyophilized pharmaceutical active to the sterile, lyophilized pharmaceutical active, sealed under a pressure of less than about 300 Torr, in less than about 10 seconds to yield, within about 5 minutes, an administrable pharmaceutical active-containing composition.

  • Publication number: 20110154682
    Abstract: A device for storing a material to be lyophilized includes a support panel, a sidewall, an opening, a cover, and at least one lifter device. The sidewall and the support panel define a storage space for accommodating a material. The opening is defined by a rim of the sidewall. The cover is removably disposed adjacent to the rim of the sidewall for closing the opening. The lifter device is disposed between the support panel and the cover and includes a reservoir and at least one movable wall. The reservoir defines a sealed cavity containing a fluid. The movable wall is in operable communication with the fluid in the sealed cavity and engaging the cover to displace the cover away from the rim when the lifter device is subject to an ambient pressure that is less than the pressure of the fluid in the sealed cavity.
