System and method for freeze-drying and packaging
First Claim
1. A system, comprising:
- a gas-impermeable flexible container including at least a front surface and a back surface, the front and back surfaces defined in a first direction by a first dimension and defined in a second direction, which is perpendicular to the first direction, by a second dimension,the first direction having an intermediate location separating the flexible container into a first portion and a second portion;
a gas-permeable membrane located within the first portion and integrated into the front or back surface, the membrane configured to transmit air or solvent vapor out of, and resist liquid or contaminant passage into, the flexible container; and
a plurality of ports to allow for the introduction or withdrawal of a material into or out of the flexible container.

Abstract
A system and method for protecting biological or other material from contamination through the steps of filling, freeze-drying, packaging, storing and use are disclosed. A system can include a flexible container, a membrane configured to transmit air or solvent vapor out of the flexible container, and a membrane frame supporting the membrane and engaged with at least one column member. The at least one column member can be configured to maintain the membrane and the membrane frame a spaced distance from one or more contents received within the flexible container. Upon application of a downward force, the at least one column member can assume a collapsed configuration. A method can include inserting a biological material, for example, into a flexible container, freeze-drying the biological material, moving the freeze-dried biological material to a portion of the flexible container that includes at least one port, and sealing the biological material within the portion.

16. A system for freeze-drying and packaging biological material, comprising:
-
a gas-impermeable flexible container including at least a front surface and aback surface, the front and back surfaces defined in a first direction by a first dimension and defined in a second direction by a second dimension, which is larger than the first dimension; a gas-permeable membrane separate from and integrated into the front or back surface, the membrane configured to transmit air or solvent vapor out of, and resist liquid or contaminant passage into, the flexible container, and at least one port to allow for the introduction or withdrawal of a material into or out of the flexible container. - View Dependent Claims (17)
