Possible Technologies of Cryopatients’ Revival
The possibility to reanimate patients after cryostasis is substantiated by the following scientific facts and assumptions:
Aman does not die instantly
Cryonics considers death as a process comprising several stages:
1. clinical death;
2. biological death;
3. information death.
By means of crynics a person can be stabilized in the state between biological death and information death.
More details
The existing cryobiologocal methods make it possible to freeze small animals and small fragments of biological tissues with minimal damage and after that it is possible to defreeze them and return to normal function. For medical purposes, skin, keratoderma, bone marrow, seminal fluid and embryos are freezed down to the liquid nitrigen temperature for storage and subsequent defeezing. Small fragments of cerebral tissue of a full-grown organism also can be frozen safely.
It is the evidence that damage made to biological objects at molecular and cellular level during freezing with the use of cryoprotectors, is not lethal. Major damage (as a rule, cracks with the size of from several microns to several millimeters) impeding freezing and further defreezing and recovery of humans, occurs in the process of freezing large bilogical objects at organ and tissue levels due to heterogeneous structure of tissues and organs and their uneven and insufficient saturation with cryoprotectors. Though these injuries are numerous, they do not cause irreversible loss of information on the organism structure which means that there is a high possibility of their recovery in the future.
2. A cryonized body can be preserved in liquid nitrogen (that is, at – 196°) for centuries actually without any changes.
3. In the future, it will be possible to repair all damage caused by death and freezing at the cell and molecular levels. This possibility is provided by the development of nanotechnology – an area of science and technology engaged in the development of >devices consisting of several thousand atoms. The development of nanotechnology was incited by the development of the scanning tunnel mocroscope – a device enabling us to investigate substance at the atomic level. This device is primarily designed to work with separate atoms (to "see” atoms) and move individual atoms. The authors of this invention were awarded the Nobel Prize in 1986. One kind of devices developed by nanotechnology, are molecular robots, that is, robots of molecular size. They will be equipped with a miniature computing machine and manipulators that make it possible to operate molecules, for example, to move them and change their structure, that is, to perform molecular surgery. An analogue of a simplest molecular robot is a a ribosome (cell ognanelle) that in accordance with a "program” (the molecule of ribonucleic acid) builds a protein molecule of amino acids

A number of scientific publications considering technical aspects of cryonic patients reanimation is constantly growing. Outstanding American nanotechnologists (and cryonics supporters) Ralf Merkle and Robert Freitas have compiled a list of scientific publications devoted to this subject:
Reference on cryopatients’ reanimation
Who will be engaged in reanimation?
There is some ambiguity to this problem. Minimal design presupposes that it is cryonic companies that will be engaged in these activities. However, in the leading American cryo companies - the Institute of Cryonics and Alcor - they have mixed feelings towards the reanimation problem. Some cryonists advocate active efforts for the preparation of revival – research in this field, allocation of financial means from some joint fund for this purpose, etc. Some other are of the opinion that such activities are premature and draw off resources from most vital and urgent work to ensure the cryioconservation reliability.
As to KrioRus position, we shall do our utmost for the patients revival in the future, and this is clearly reflected in our contract for cryoconservation.
On the other hand, it would not be honest to make some concrete proposals, as both economical and technological situation in the future is as yet too indefinite, and it is only in tens of years that the situation in this field is clarified.
Moreover, cryonics will most probably have a short-term golden age just before revival becomes possible (as there will be a multitude of partial and preliminary achievements demonstrating the possibility of such revival). It sems to us that it will make the state (society) to take measures to clarify cryopatients’ fate and to determine guarantess and procedures of their reanimation.
Therefore, in general our position can be expressed as follows: after revival becomes technologically feasible, there will emerge a whole range of so far unknown organization possibilities for patients reanimation. Our basic objective is to secure the realization of at least one of these possibilities and until then to preserve a patient with maximum reliability.
