Abstract:
1. A method of preparing an arteriovenous graft consisting essentially of: i) washing a starting tissue obtained from a human or animal ureter with at least one bioburden reducing agent so that said starting tissue is disinfected, ii) decellularizing the disinfected tissue resulting from step (i) with a solution that lyses cells of said disinfected tissue so that a decellularized tissue matrix is formed, iii) contacting said decellularized tissue matrix resulting from step (ii) with at least one nuclease so that nucleic acid associated with said decellularized tissue matrix is degraded, and iv) washing said decellularized, nuclease-treated tissue matrix resulting from step (iii) so that cellular or extracellular debris is removed and said arteriovenous graft is obtained.
