A medical treatment device consisting of a modified Hepatitis C virus, said Hepatitis C virus modified to have a quantity of surface probes to recognize, then engage one or more exterior cell-surface receptors on the surface of a Beta cell located in the Islets of Langerhans in the pancreas, said medical device expressing said quantity of surface probes intended to facilitate inserting said modified Hepatitis C virus's genome that it carries into said Beta cell, said modified Hepatitis C virus further modified to have its own innate positive sense ribonucleic acid genome replaced by a quantity of ribosomal ribonucleic acid molecules for the purpose of carrying out a medically therapeutic treatment,
- whereby once said modified Hepatitis C virus inserts said quantity of ribosomal ribonucleic acid molecules into said Beta cell, said quantity of ribosomal ribonucleic acid molecules are intended to engage ribosomal proteins to produce ribosomes, said ribosomes to decode messenger ribosomal acid molecules to produce proteins, the result of which is intended to produce a medically beneficial therapeutic effect.
