About jemet Jaqua ™️ Hydrophilic super smooth coating

Interventional therapy is a new high-tech minimally invasive treatment technology in modern medicine. It has the characteristics of small trauma, multiple indications, accurate curative effect and rapid postoperative recovery. It is an important development trend of medicine in the future.

Interventional catheters play an important role in surgery. Most of the outer polymer materials used to make interventional catheters are hydrophobic, such as polyurethane (TPU), polyether amide (PEBAX) and nylon (PA). These materials have high friction and will cause varying degrees of damage to human tissues and blood vessels. However, coating the surface of medical catheters with hydrophilic coatings can effectively reduce the surface friction, So as to reduce the harm to human body.

Therefore, it is necessary to coat hydrophilic coating on the catheter and guide wire of interventional therapy.



jAqua ™️ Why can hydrophilic super smooth coating be recognized by the market?


Gemet coating, established in 2013, is the first enterprise in China to independently develop and produce medical hydrophilic super smooth coating, breaking the monopoly of foreign hydrophilic coating market and providing a new and reliable choice for domestic and foreign medical device manufacturers.

In 2014, gemet coating signed a strategic partnership with the Singapore Research Council (a*star), established a partnership with the National University of Singapore, Nanyang Technological University and other world-class universities, independently developed hydrophilic coating and heparin anticoagulant coating to inhibit thrombosis, and holds the patent of hydrophilic coating and anticoagulant coating independently developed.

In 2017, gemet hydrophilic super smooth coating was filed with FDA.

Up to now, more than 50million cardiovascular catheters have been coated with gemet hydrophilic super slippery coating. The market share of hydrophilic coating in China exceeds 80%. Most of the cooperative customers are large listed medical device manufacturers.



Four characteristics of gemet hydrophilic super smooth coating


1. lubricity


Lubricity is the surface characteristic of a material, which is measured by the surface friction coefficient.

The hydrophilic coating has the characteristics of water affinity. The negative charge of the coating will combine with the dynamic hydrogen bond in water, which is conducive to the mutual fusion of the coating and the aqueous solution.
The physical interaction between the coating and water will form a gel material, which will show a very low friction coefficient, thus changing the surface characteristics of the conduit to achieve the effect of lubrication.
The lubricating surface of the catheter with hydrophilic coating on the surface reduces the intervention force, which makes it easier for the instrument to penetrate the blood vessels, avoiding the possible puncture of human blood vessels and tissue friction damage.



2. firmness / stability

It can be seen from the friction test chart that the friction of the guide wire with hydrophilic coating is uniform and stable after 25 times of round-trip friction.

It can be seen that gemet hydrophilic coating will not easily fall off the surface of the guide wire, and has good firmness and stability.

This means that the hydrophilic coating will not fall off due to friction during normal operation, resulting in increased catheter friction or residues left in human tissue, with a high safety factor.



3. uniformity


The surface of the catheter with gemet hydrophilic coating is smooth and uniform without particle feeling. The attached hydrophilic coating can be evenly dispersed on the surface of the catheter, which makes the hydrophilic coating catheter more lubricated.

4. good biocompatibility


Gemet hydrophilic coating uses PVP as the substrate. As a synthetic water-soluble polymer compound, PVP has the general properties of water-soluble polymer compounds.
PVP has excellent physiological inertia, so that it does not participate in human metabolism, has excellent biocompatibility, and does not form any irritation to skin, mucosa, eyes, etc. PVP can also be used as colorant and X-ray contrast agent; It can be used in tablet, granule, water agent and other dosage forms. It has the functions of detoxification, hemostasis, improving dissolution concentration, preventing peritoneal adhesion, promoting ESR and so on. It is a substance that has been widely used and its safety has been verified.
Gemet hydrophilic super smooth coating has been proved to be safe and stable in clinical applications at home and abroad. Compared with the hydrophilic coating of other raw materials in the market, the hydrophilic coating of gemet has better biocompatibility.
