title: An efficient, compact and simple-to-use blood gas exchanger for long-term use.
abstract: The CCF folded coil membrane oxygenator has demonstrated a high capability for mass transfer both in vitro and ex vivo. The membrane-gas net interaction currently under investigation has indicated improved transfer with more controlled blood film thickness. The gas net being evaluated at this time in 3 layers: an open weave inner layer and net number 024 as a direct membrane support structure. No serious adverse effects of ex vivo bypass were found in 4 trials, and in long-term experiments, no deterioration of oxygenator performances could be found. The position of the oxygenator on the pump console and the absence of auxiliary frames, motors or pumps simplify operation of this device. It is felt that, following further detail refinement and ex vivo and clinical testing, this device can be presented as a suitable answer to the need for an efficient, simple to use, and versatile membrane oxygenator.
