Overview
- Nitschke demonstrated the Kairos Kollar at an Exit International workshop, presenting it as a new drug-free assisted-dying device.
- He says the collar compresses the carotid arteries and baroreceptors to cut brain blood flow, causing rapid unconsciousness and then death.
- He publicly promoted the device as “fast, reliable, drug-free” and described it as “unrestrictable.”
- He also outlined a separate concept under development called a “suicide switch,” an implanted timer intended to end a life if not reset by a person with capacity.
- The unveiling follows controversy around his Sarco pod, used by an American woman in Switzerland in 2024, a case that led to arrests before homicide charges were dropped and that drew product-safety criticism.
