Patients wishing to be cryopreserved sign up for a membership with Tomorrow.bio. We help them get the necessary paperwork in order, ensure there’s insurance or funds in place to pay for the cryopreservation procedure and stay ready to cryopreserve them whenever death occurs. For people signing up at the last minute, we have special rates.
Step 2
Dispatch
Most deaths can be predicted by medical conditions and circumstances. When there are signs that a patient might be dying, we dispatch one of our ambulances with a biostasis response team. They usually arrive before death occurs, allowing us to start the stabilization process as soon as the patient is legally pronounced dead.
Step 3
Stabilization
We cool the patient down as quickly as possible using ice and water. Then we initiate cardiopulmonary support (CPS) and infuse them with neuroprotective and anti-clotting medication. This stabilizes the patient, slows down the degradation process, and prepares the patient for cryoprotection.
Step 4
Cryoprotection
Our ambulances are fully equipped to perform field cryopreservation, allowing us to get right to work: During our cryoprotection procedure, we will slowly replace the patient’s blood with cryoprotectant and cool them down further. The cryoprotectant protects the body during the cooldown.
Step 5
Transport
We transport the patient to our storage facility in Switzerland.
Step 6
Cool-down
At the facility, the cryoprotected patients are placed in a cool-down chamber. As quickly as possible, we cool them to -120°C, where they will undergo a process called vitrification, which is a glass-like transition of the body. Following this process, we slow the cool-down to about 1°C per hour to avoid thermal stress. Cool-down finishes when the patient has reached -196°C.
Step 7
Storage
Patients are placed in a pod, which is then placed in a cryogenic dewar filled with liquid nitrogen. Here they are stored indefinitely, with no electricity required. The liquid nitrogen is regularly refilled by the on-site team or an automated system.
