Larraman's Organ, also called the Healer, is the 5th of the 19 gene-seed organs that are implanted into a Space Marine Neophyte to produce a new Astartes. Shaped like the human liver but only the size of a golf ball, this gene-seed organ is placed within the chest cavity and manufactures the synthetic biological cells known as Larraman Cells that were named after one of the researchers in the Emperor of Mankind's gene-laboratories on Terra where the gene-seed for the first Space Marines was created under the Emperor's direction from his Primarchs' DNA.
