Engineering Development

After tests with the cold stage of the new perfusion system, the cold
stage has been returned to the manufacturer for modification or possible
replacement. While it was cooling deep enough, it was not fast enough or
even enough for our purposes. The modifications will allow larger volume
and faster gas flow. Additional changes are being made to the wiring
bus of the Advance Cryoprotection System.

The new ATP system has been successfully tested with liquid. We are
currently going through an iterative process of packing it in a
shipping case along with the required perfusate. Indications are, as
we had hoped, we will be able to include the entire system in one
shipping case.
