Aphasia device
The aphasia device was the mechanism through which Dekon Elig and Surmak Ren intended to deploy an aphasia virus aboard Terok Nor. 

During the Occupation of Bajor in 2351, the device, with a diboridium core as  source, was attached to the pattern generator of a single replicator on the station, which would change the materialization subroutine and insert the virus directly into the molecular level of the replicated items. Intended to release the virus to the Cardassians, the device did not activate until 2369, after the Cardassians had abandoned the station and it had come under Bajoran control. ()
