*Potential transplant recipient* or *potential recipient* means a transplant candidate who has been ranked by the OPTN computer match program as the person to whom an organ from a specific cadaveric organ donor is to be offered.
*Scientific Registry* means the registry of information on transplant recipients established pursuant to section 373 of the Act.
*Secretary* means the Secretary of Health and Human Services and any official of the Department of Health and Human Services to whom the authority involved has been delegated.

*Vascularized composite allograft* means a body part:
(1) That is vascularized and requires blood flow by surgical connection of blood vessels to function after transplantation;
(2) Containing multiple tissue types;
(3) Recovered from a human donor as an anatomical/structural unit;
(4) Transplanted into a human recipient as an anatomical/structural unit;
(5) Minimally manipulated (i.e., processing that does not alter the original relevant characteristics of the organ relating to the organ's utility for reconstruction, repair, or replacement);
(6) For homologous use (the replacement or supplementation of a recipient's organ with an organ that performs the same basic function or functions in the recipient as in the donor);
(7) Not combined with another article such as a device;
(8) Susceptible to ischemia and, therefore, only stored temporarily and not cryopreserved; and
(9) Susceptible to allograft rejection, generally requiring immunosuppression that may increase infectious disease risk to the recipient.
