Cryotec is a cryopreservation storage device that is intended for use in vitrification procedures to contain and maintain human 4-8 cell or blastocyst stage embryos. It is designed to enable physicians and embryologists to preserve and to store vitrified embryos for assisted reproduction technology procedures. The Cryotec device is composed of a two piece assembly with a polyethylene terephthalate (PET) film sheet attached to a PET handle, and a weighted polyvinylchloride cap to cover the film sheet during handling and storage. During vitrification procedures, the film sheet is loaded with embryos, capped, and immersed in liquid nitrogen. The capped design creates a hermetic seal, resulting in a closed system keeping the film sheet and embryos isolated from liquid nitrogen. The cap is weighted to allow proper alignment in the storage container. The Cryotec device is provided sterile and is for single use only. The Cryotec device has been designed to maintain the integrity of the human embryos the freezing and thawing process.
