Hyperbolic pulse generator. Exorcisms are unreliable. This device emits a force that drives the possessing demon from the vessel.
The hyperbolic pulse generator is a device created by the British Men of Letters, used to expel demons from vessels. A combination of technology and magic, the egg-shaped device is adorned with various sigils that will light up once an activation sigil is triggered with the blood of the user. The user will then recite Latin, as a powerful pulse emanates from the device and forces the demon out of the body. Despite its initial intent for exorcizing demons, the device is shown to be capable of exorcizing even an archangel from its vessel.
After saving the Winchesters from the Secret Service, Mr. Ketch shows them his arsenal, including the Hyperbolic Pulse Generator. Recognizing its potential against Lucifer, Sam and Dean convince Arthur to give it to them.
Luring Lucifer into a trap with the aid of Kelly Kline, the Winchesters get Lucifer alone in a motel room with Kelly. When she tells Lucifer that she can't have his child, he snaps and begins choking her. Sam then emerges from the bathroom with the pulse generator in hand. He actives a blood sigil on the door and recites the phrase "vada retro princeps inferni" causing a powerful pulse to beat Lucifer back. At the same time, Rowena begins the spell to send Lucifer back to his Cage. Lucifer, believing he is going to lose, tells Sam that it's not over, only to have Sam tell him to go to Hell. Lucifer then vacates President Jefferson Rooney, his essence swirling around the ceiling before disappearing down a heating vent next to Sam. Later, Castiel takes the device and flees alongside Kelly.
