Nash, 55, is being treated in the prestigious Cleveland Clinic for severe and debilitating injuries she suffered when Travis mauled her in February.
Nash lost her hands, nose, lips and eyelids in the 12-minute attack, officials at the Cleveland Clinic said. Many bones in her face were crushed, and the attack might also have left her blind and brain damaged.
"No amount of money can compensate my sister for the injuries she has suffered," Nash's brother Michael, the appointed conservator of his sister's estate, said in an affidavit.
