Polyzene-F Makes the Difference

“I believe Polyzene-F will continue to play an important role in delivering safety and efficacy in clinical practice.”
— Aloke Finn, MD, Medical Director and Chief Scientific Officer at CVPath and Associate Professor of Medicine at the University of Maryland

The Future of Medical Device Implants

Alta Biomed develops and manufactures novel surface coated technologies including its proprietary Polyzene-F nanocoating and COBRA SG Drug-Coated PTCA Balloon technology. This next-generation innovation is transforming clinical practice and promoting positive outcomes in patients around the world.

Polyzene-F™ NanoCoating A Legacy of Safety

Now, for the first time ever, medical device manufacturers seeking to optimize implant interaction within the body can partner with Alta Biomed to apply the revolutionary PzF nanocoating to their technology.

Our revolutionary drug-free polymer, Polyzene-F (PzF), is imparted with the following unique properties observed in pre-clinical studies:

  • Anti-thrombogenic

  • Anti-inflammatory

  • Rapid & complete healing*1-5

Applications:

  • Vascular Implants (e.g., peripheral and coronary stents, neurovascular implants, vena cava filters)

  • Microspheres

  • Structural Heart

  • Surgical Meshes

  • PICCs

  • LVADs

  • Can load and elute drugs

  • Anti-stick coating

 

Material Compatibility:

  • Metal/metal oxide

    • Nitinol

    • Cobalt-Chromium

    • Stainless Steel

    • Titanium

    • Magnesium

  • Polymers/Textiles

 Powerful Passivation & Pro-Healing* Technology

Polyzene-F™ (“PzF”) is a nano-thin biomimetic surface coating that acts as a barrier between the device, intimal surface and circulating elements in the blood.

Thrombo-Resistance

Fewer platelets adhere to PzF Nanocoating1-3,6

Anti-Inflammatory

Significantly Lower Vessel Injury with COBRA PzF Stent 1-5

Less Inflammation, Neointimal thickness, area, and struts with granuloma.

“Polyzene-F has the potential to significantly limit a wide range of implant complications.”
— Professor Dr. Michael Grunze, Ruprecht-Karls-University in Heidelberg, Co-inventor of Polyzene-F

History of Commercial Success

Cardiology - COBRA PzF NanoCoated Coronary Stent (NCS)

PzF nanocoated, non drug-eluting coronary stent allows physicians to safely and effectively treat patients with short 1-month DAPT.1

Oncology/Radiology - Embozene™ Microspheres

PzF nanocoated spheres are designed to be virtually “invisible” to the body, reducing inflammation and unwanted tissue reaction.

Acquired by Boston Scientific in 2015. Read Press Release.

Oncology/Drug Elution - Tandem™ Microspheres

PzF nanocoated spheres are designed to be virtually “invisible” to the body, reducing inflammation and unwanted tissue reaction.
