OPTN: Organ Procurement and Transplantation Network: "The U.S. Organ Procurement and Transplantation Network (OPTN) helps ensure the success and efficiency of the U.S. organ transplant system. OPTN responsibilities include:

developing consensus based policies and procedures for organ recovery, distribution (allocation), and transportation
collecting and managing scientific data about organ donation and transplantation
providing data to the government, the public, students, researchers, and the Scientific Registry of Transplant Recipients�[Exit Disclaimer], for use in the ongoing quest for improvement in the field of solid organ allocation and transplantation
developing (1999) and maintaining a secure Web-based computer system, which maintains the nation's organ transplant waiting list and recipient/donor organ characteristics
providing professional and public education about donation and transplantation, the activities of the OPTN and the critical need for donation"

Importantly, none of these responsibilities include "preventing any operation from occurring outside the network."
