Innovative GORE(TM) LYOGUARD® Tray System to Deliver Freeze-Dried Plasma to Military


Elkton, MD (January 08, 2009) - W. L. Gore & Associates, Inc., announces an innovative GORE(TM) LYOGUARD® Freeze-Drying Tray System for exclusive, proprietary use by HemCon Medical Technologies, Inc., as the delivery system for its new freeze-dried plasma product for the United States Army. Recently awarded a U.S. government grant to develop, test, and secure FDA approval for a lyophilized (freeze-dried) human plasma (LHP) product, HemCon turned to Gore for a stable, contaminant-free delivery system for the plasma.

GORE(TM) LYOGUARD® Freeze-Drying Tray System

HemCon worked closely with the U.S. Army to develop specifications and requirements for a packaging system that could eliminate the current logistical barriers to using fresh frozen plasma in the field. By using GORE(TM) LYOGUARD® Trays, HemCon can fill, freeze-dry, and reconstitute the plasma in Gore's innovative "closed" system. If trials are successful, the U.S. Army will be able to transport the LHP more easily without the need for refrigeration. The medical team can then reconstitute the LHP in less than two minutes, rather than having to wait 20 minutes to thaw frozen plasma - a time difference that can save a life.

GORE(TM) LYOGUARD® Freeze-Drying Trays use a proprietary ePTFE membrane to create the closed-system design that reduces contamination of the plasma. This membrane prevents liquids and particulates from passing through the membrane, while at the same time, allowing freeze-drying to occur by letting vapors and gases flow through freely.

Fred Giordano, applications engineer at Gore, described the configuration of the tray for HemCon. "One of Gore's core values is to deliver products based on fitness for use, which means that we deliver the best product to meet or exceed the customer's expectations for its specific application. The GORE(TM) LYOGUARD® Tray is proven technology that has been used for many years in freeze-drying pharmaceutical products. HemCon needed a smaller tray in which to process the plasma and a container that could be used for transport. We configured a tray that holds one unit of plasma, and we added a cover that improves processing and protects the LHP during transport."

HemCon selected the GORE(TM) LYOGUARD® Freeze-Drying System as a container for its freeze-dried plasma because of prior experience working with Gore's innovative products. Simon McCarthy, Ph.D., global head, chief scientist of research at HemCon, describes their relationship with Gore, "We have used Gore's freeze-drying products successfully with our current hemostatic HemCon® Bandage. For the freeze-dried plasma project, we partnered to adapt a GORE(TM) LYOGUARD® container that met our specifications for field use, ruggedness, and size. We desired a container that could protect the plasma before, during, and after the lyophilization process itself, and in addition, be easily and safely transported without compromising the LHP. We are confident that the technology behind GORE(TM) LYOGUARD® Freeze-Drying Products will enable us to provide a delivery system that meets the needs of the U.S. Army."
