The Bavakar cardio package, a cybernetic brain implant, saw use during the Jedi Civil War that pitted the Galactic Republic against the Sith Empire. Bavakar Medical Research Labs, regarded as the foremost cybernetics laboratory of that time, was the manufacturer of this implant. Costing two thousand credits, the device was a potent form of cardio package. It significantly enhanced the cardiovascular health of an organic user, surpassing natural limits by stimulating the brain to release specific chemicals that affected organs like the heart. Due to their complexity, these implants necessitated specialized training for users, who could only utilize one at a given moment.
Shasa, a female Selkath residing on the Inner Rim planet Manaan in 3956 BBY, utilized a Bavakar cardio package. She underwent brainwashing and training in the dark side at the waterworld's Sith Embassy. Revan, a former Sith Lord who was retrained as a Jedi Padawan, raided the embassy, ultimately freeing Shasa from the influence of the Sith.
The 2003 video game Star Wars: Knights of the Old Republic, a creation of BioWare, marks the initial appearance of the Bavakar cardio package as an obtainable equipment item. Players can only acquire this implant by killing Shasa during the "Missing Selkath" quest. However, the seventh web enhancement for the Knights of the Old Republic Campaign Guide clarifies that Revan rescued Shasa, allowing her to survive, thereby confirming that Revan chose the light side path in this quest.
