Pulmonodes

Pulmonodes were mechanized replacements for the heart and lungs. Most people who received pulmonodes kept them visible temporarily, until they went through the bacta sessions necessary to grow new flesh and skin around them. They had orange status lights.

Breha Organa was given them after she suffered a near-fatal mountaineering accident though she chose not to go through the bacta sessions to cover them up. When Breha's daughter, Leia Organa, was a small child she used to believe that the glowing lights from the pulmonodes in her mother's chest was a bouquet of blooming candlewick flowers.
