Structural Heart Disease

GKS

Bi-leaflet Prosthetic Heart Valve



 





Over 20 Years Clinical Applications



There were more than 50,000 pieces of GKS Bi-leaflet Prosthetic Heart Valve have been implanted with excellent outcomes.









Product Features


 

High Performance Material

The leaflets and hinge ring are made by pyrolytic carbon, which guarantees the excellent biocompatibility and superior safety.  




Open Pivot Design



Sufficient Blood Washing   The open pivot design avoids the structure of cavity area, where may result in the blood silting and eddy forming, providing sufficient blood washing to reduce the risk of thrombosis.

Less Damage to Blood Cells   
Comparing to the cavity pivot structure, the open pivot design reduces the shear stress that acts on the blood cells, and minimizes the damages to them.

Gentle and Smooth Blood Flow   The open pivot design makes the blood flow go through without block, running gently and smoothly.



Suspending Leaflets Design

Flexible & Fast Open and Close   The suspending leaflets design provides flexible and fast open and close to ensure more smooth blood flow, and satisfy the physiological needs.

85° Leaflet Opening   
The 85° leaflet opening provides improved laminar flow, and reduces the turbulence.



Separated Hinge and Leverage Design


Long-term Safety   
The hinge and leverage are separated to reduce the stress when the leaflets open and close, effectively avoiding the fatigue and providing long-term safety.

Lower Noise   
The buffering caused by blood flow reduces the noise when the leaflets open and close, providing quieter function and better life.

Automatic Adjustment   
The hinge ring can be automatically rotated to the specific place for the best effect of hemodynamics when the patient is in different positions.
