  • As people age, the wear and tear on individual organs—such as the heart, lungs, liver, or kidneys—becomes a limiting factor, outpacing the body's overall ability to sustain longevity.

  • We believe that every human in a need of an organ transplant should be able to get it immediately.

  • To achieve this a significant enhancement of the organ preservation and delivery is required to withstand both organ deterioration and logistical challenges.

  • We develop cost efficient and reliable organ preservation technology and device that allow dramatic increase procurement distance with no load on organ quality.
The increasing global life expectancy leads to new challenges in healthcare

Our projects
We believe that every human in a need of an organ transplant should be able to get it immediately
Heart transplantation is a life-saving procedure for patients with end-stage heart failure, offering them a chance at a renewed quality of life and extended survival.
01
Heart preservation
Lung transplantation is a critical intervention for patients with end-stage lung disease, offering them the possibility of improved quality of life and prolonged survival.
02
Lungs preservation
We develop container for limbs preservation. We plan to use modified InPres technology to provide better quality and longer term of preservation.
03
Limbs preservation at Udin center
We believe that we can find some spots to enhance the quality of biomaterial preservation for IVF.
04
IVF with MSU
Animals selection and breeding are the potential areas where our technology can give a boost.
05
Cattle/fish-breeding with Saint Petersburg Agriculture university
PhD and MD in lab medicine and academic researcher in cryobiology. In hospital, he is deeply involved in both cell sorting and cryopreservation of human bone marrow and hematopoietic stem cells helping patients to get healthy, viable and non-harmful donor grafts.

His area of expertise is in developing and evaluating new approaches in the Biobanking to storage cells, tissues and organs.

The main purpose of his research has been to develop a new storage method and device that uses gas mixture for the preservation of viable cell or tissue grafts for transplantation.
