Superior and effective drug-free medical device coating

There is a significant issue with current treatments for peripheral artery disease (PAD) using stents.

From preventing blood clots or reducing infection, to minimising painful fibrosis associated with implants, BIOINVISIBLE offers a more sustainable and recovery-driven solution to patients and industry.

It is anti-thrombogenic, anti-proliferative and evidence also now demonstrates extreme reduction in biofilm.

Superior drug-free vascular device coating

Get the leading medical device coating technology that prevents the build-up of platelets, proteins and cells.

BIOINVISIBLE is a highly biocompatible coating that helps to make implantable materials less ‘visible’ to the body’s normal immune defences.

Currently, medical device complications result in implant failure rates of up to 30%, leaving many patients requiring additional medical intervention and surgery causing significant discomfort, morbidity or even death.

BIOINVISIBLE™ is the solution to reducing this failure rate.

Evidence it works

The Process

We use a patented process where devices are coated with BIOINVISIBLE, a hydrophilic hyperbranched polyglycerol (HPG) polymer. This process allows the polymer to form directly from the surface of devices without the need for solvents.

Devices coated with BIOINVISIBLE repel platelets that can cause blood clots and potentially life-threatening complications for patients.

BIOINVISIBLE is easily applied to a wide range of metallic and polymer-based materials used in medical devices.

Vascular stents coated with BIOINVISIBLE repel platelets. This prevents blood clots which can lead to potential life-threatening complications for patients.

The BIOINVISIBLE process has patents granted in the US, Europe, China, Japan and Australia.

Reducing platelet adhesion on vascular stents

Platelets are implicated in the development of stent thrombosis and in-stent restenosis. For a patient receiving a stent, the formation of fibrin clots on the surface of the stent can lead to larger and life-threatening blood clots that can block arteries, requiring emergency surgical intervention.

TekCyte’s BIOINVISIBLE coating creates a barrier on the surface of stents, which means the blood can flow normally over the stent surface. This reduces platelet adhesion and activation, greatly reducing the likelihood of a blood clot.

The unique coating has the potential to not only reduce complications from vascular devices, but it may also reduce the need for long-term anti-coagulant therapy for many patients requiring these devices.

Mouse models of restenosis show that BIOINVISIBLE coated stents significantly reduce the level of in-stent restenosis, compared with uncoated stents.
