Triflexia

Triflexia was a disease which attacked the blood vessels, causing their walls to inflate their cells three times the normal size. As well as increasing the blood pressure, it also cut off oxygen exchange in the lungs, throttled the esophagus and crushed brain tissue in the skull. Rebel scientists were searching for a cure for it during the Galactic Civil War, but what they did not know was that it had in fact been bioengineered by the Galactic Empire for use as a poison. Imperial spy Tanya Madera used this poison to kill both Chief Technician Adonar Dellox and one of the X-wing pilots from Reginard Base. To adminster it, she used a needler pistol.
