gift of decedent's body or part.

A. A person authorized to make an anatomical gift under Section

receiving the oral communication.

B. Subject to subsection C of this section, an anatomical gift

by a person authorized under Section 9 of this act may be amended or

reasonably available. If more than one member of the prior class is

reasonably available, the gift made by a person authorized under

Section 9 of this act may be:

members agree to amending the gift; or

2. Revoked only if a majority of the members agree to the

revoking of the gift or if they are equally divided as to whether to

revoke the gift.

C. A revocation under subsection B of this section is effective

only if, before an incision has been made to remove a part from the

donor’s body or before invasive procedures have begun to prepare the

recipient, the procurement organization, transplant hospital, or

physician or technician knows of the revocation.
