Prosthetic
heart valve “Planics”
 The invention relates to prosthetic heart valve
"PLANICS" for implantation into the human heart instead of damaged
valve. The prosthetic heart valve includes: valve body, disk-shaped occluder,
sewed cuff.
The body and disk have a streamline and polished form and are
manufactured with high accuracy. This makes minimum the possibility of
trombogenicity in a valve.
The asymmetry element, which is in construction,
promotes disk pivoting relatively its center. This reduces the wear of occluder.
For optimal orientation of the valve, during the implantation, its body can turn
over in sewed cuff.
Prosthetic heart valves "PLANICS" are of the
following types and have the following dimensions:

valves have an angle of pivoting of the disk 73° and mitral valves — 68°.
Each valve undergoes thorough 100% testing of
major characteristics before utilization in hospitals.
All valves are delivered secured in special
holders and sterile packages.
