About artificial heart valves:

Artificial heart valves are implanted in the heart of the patients who need treatment for valve related diseases.
The natural heart valve needs a replacement when two or more valves stop functioning properly.
Generally an open heart surgery is performed to replace the valve.
There are two types of artificial heart valves –
1. Mechanical heart valve and
2. Tissue heart valve
The mechanical heart valves last almost indefinitely, however, they need continuous treatment with anticoagulants.
The tissue valves on the other side do not need anticoagulants, however, they have shorter life span. Typically the tissue valves command 10% or less market in the heart valves market.

Product characteristics:

The heart valve has three parts:
1. A metallic housing,
2. A disc or ball (which functions as occlude) and
3. A sewing ring (made of synthetic material).
The functional requirement of heart valves are as follows:
1. Minimum regurgitation
2. Minimum trans-vascular pressure gradient
3. Non-thrombogenic
4. Low wear/tear
5. Minimal leakage
6. Appropriate valve orifice to anatomical orifice ratio
The motorized heart valve consists of Ultra high molecular weight-polyethylene (UHMW-PE) disc, Low density polyethylene plastic with knitted polyester sewing ring and a metallic housing.
The stitching Ring is made-up from expansively implant tested, 100% polyester fabric. The Sewing Ring fabric is warp - knitted in a precise outline using texturized yarn with excellent tissue ingrowths and long term blood compatibility.

Raw-materials and machinery:

The motorized heart valve consists of Ultra high molecular weight-polyethylene (UHMW-PE) disc, Low density polyethylene plastic with knitted polyester sewing ring and a metallic housing.
Heart valves are manufactured using warp-knitting process on Double Raschel Warp knitting machines.
