Abstract: A container assembly (10) comprises a vessel (21) for containing a biological medium, gametes and/or one or more embryo(s). The vessel (21) has a CO2 permeable seal (28) and a closure device (30) for selective access. A buffer chamber (60) for a CO2 enriched atmosphere at least partially surrounds the vessel and is defined by a shell (61). The buffer chamber is in communication with the CO2 permeable wall. Such a container assembly is particularly adapted for IVC in which case the permeable seal (28) prevents ingress of vaginal secretions. The buffer chamber (60) mediates the aqueous pH in the vessel after the container assembly is removed from a CO2 enriched environment.

Abstract: A speculum for use with a body opening, such as a vagina, rectum or surgical wound, may have an insertion portion with an arcuately-shaped wall and a slot that extends along a length of the wall. An end face of the wall at the distal end of the insertion portion may be arranged at a non-perpendicular angle to the longitudinal axis of the insertion portion. A flange portion joined at a proximal end of the insertion portion may have a continuous band that extends radially outwardly from the wall and includes a notch that communicates with the slot. A handle portion may have a gripping surface extending proximally at a bottom side of the flange portion with an arcuate shape that is approximately concentric with the wall of the insertion portion. A top side of the flange portion may be free of the handle portion.
