Response to our visitors' Request

In response to outstanding interest of the medical and scientific communities toward this WebPages, the SIA Co. is ready to offer the following assistance and services:

1. Private suitcase consulting sessions for the following areas:

• Methods of the formation of the aortic pressure
pulse by electromechanical means

• Methods of the formation of the aortic pressure
pulse by hydromechanical means

• Methods of mathematical simulation of
the hydrodynamics of a blood propagation in
the blood circulation system (BCS)

• Development and design of the TAH
able to simulate natural (physiological shape of pulse)

If your are interested in private consulting by Dr. Eugene Mogendovich send your request to us via e-mail (see home page)

2. If the sufficient number of participants will appear, the SIA may organize the seminar. The topics are following:

• The TAH, as an information - energy hydraulic pulse (IEHP) system.
- Base concepts, terminology, definition
- Theory of the (IEHP) systems
- The elements of the HP systems
- Theory of the HP systems
- Properties of hydraulic pulses
- Hydrodynamic methods of simulation of HP systems


• Current status of development of the TAHs in view
of the simulation of the natural shape of pulse

• Main direction in the simulation of the natural shape of pulse

• Biological aspects of the pulse shape in the BCS and TAHs

• Medical aspects of the deviation of pressure pulse shape
from the physiological form

• Position of the NHLBI on this matter and its influence
on the development of TAH.

If you are a medic professional or a scientist involved in area of TAH
implanting and/or development we would like to hear from you.

The story:
The Total Artificial Heart

• The Total Artificial Heart (TAH) can save
lives of 70,000 people a year in the USA

• Since 1982, the National Heart, Lung
and Blood Institute of the NIH had spent
more then $100 M for R&D of the TAH

• None of the developed TAHs work for more
then a few month

• Why it does not and what may work?

• None of the TAHs simulates (reproduces) a
Natural Shape of the Physioiogical Pulse

What are properties of the natural pulse?

• Natural pulse has a 50% diastole time, which gives heartand blood vessels time to relax • Natural pulse has a very steep front:

Why it is so important to simulate Physiological (Natural) Pulse?

• Steep front (blood acceleration) induces a pressure wave

• Pressure wave creates a wave phenomenon (similar to
a water hammer effect), which:
- expands walls of blood vessels, allowing more blood flow
- to move with lower pressure
- reinforces muscles of blood vessels
- removes obstakles inside the blood vessels
- pushes blood through tiny capillaries

How It Could Be Done?

• In 1992the USA patent #5,139,516: "Artificial
Heart and Method of Operating the same",
was granted to Dr. Eugene M. Mogendovich.

• The patent among other novelties introduces
the method of simulation of the Natural
(Physiological) Shape of Pulse.

• The TAHs, which reproduces the natural shape of
pressure pulse has been designed and developed.

• Dr. E. Mogendovich and his team can provide
consulting and help improving the TAHs designs.
