In the last five years, 18 people donated their organs posthumously at Great Western Hospitals, saving the lives of 47 others across the country.
Mr Murphy, said: “I know first hand how important the circle of life is and wanted to show this through my art.
“I’ve chosen to entwine various organs into the brass to show how everyone is joined together through the extraordinary process of organ donation.”
Organ donation in England is done under an “opt-out” system, meaning all adults are presumed donors unless they register to opt out.
However, people are encouraged to register their wishes on the NHS Organ Donor Register, external as the family of a potential donor is always consulted.
Consultant anaesthetist and chair of the Organ Donation Committee, Malcolm Watters, said a single person could save “up to nine lives” by choosing to donate their organs after death.
“Only a very small number of people die in a way that it is possible for them to be organ donors, so the more people who register as donors, the better chance we have of organ donation being possible,” he said.
Across Wiltshire, 93 people are currently waiting for an organ.
