Cell-free allografts should be ordered at least two months before the planned surgery date in order to allow for the acceptance and the allocation of an appropriate allograft by the EHB (which can take up a couple of weeks) and the decellularization process by Corlife (which takes about 4-6 weeks).

Invoicing of cell-free valves is twofold: a first invoice will be issued by the EHB for covering the costs of donation, procurement, packaging, shipment from the procurement centres to the EHB and the dissection, morphological and functional evaluation costs of the EHB; a second invoice is then issued by Corlife for the decellularization of the valve.
