Eviva® and Veriva®: Polymer Powerhouses Reshaping the Future of Medical Implants
While metal materials like stainless steel and titanium have long been trusted for medical implants, advanced polymer materials, backed by a proven history, are increasingly being adopted in implant applications, offering several distinct advantages.
Implantable Polysulfones: A Proven Choice
For nearly two decades, implantable polysulfones have been a unique and versatile material for a wide range of medical applications. Syensqo is the exclusive resin supplier offering these materials in implantable polysulfone (PSU) and polyphenylsulfone (PPSU), branded as Eviva® and Veriva® respectively. These advanced polymers excel in non-load bearing and active implant applications, including access ports, cardiovascular and neurovascular components, drug delivery devices, craniomaxillofacial and dental applications, wire coatings, and more.
Unique Advantages of Implantable Polysulfones
In addition to meeting all the critical requirements for medical implant materials—such as excellent strength, dimensional stability, chemical resistance, and biocompatibility—implantable polysulfones offer several unique advantages.
The transparent properties of Eviva PSU and Veriva PPSU facilitate easy visualization, which is particularly important during medical procedures where monitoring is essential. For instance, in drug delivery devices, the ability to observe the flow of medication can be vital.
Implantable polysulfones are also radiolucent, allowing artifact-free medical imaging in X-ray, MRI, and CT scans. This feature significantly enhances the ability of medical professionals to monitor post-operative care effectively.
Eviva PSU and Veriva PPSU exhibit excellent insulative properties, characterized by low thermal conductivity and superior electrical insulation. These attributes ensure that the polymer materials do not disrupt electrical signals within a device, a feature that is increasingly important as medical devices become more technologically advanced.
In terms of chemical resistance, implantable PSU and PPSU are exceptional. They exhibit excellent resistance to aggressive chemicals and bodily fluids, ensuring the materials remain stable and do not degrade over time. The physical properties of Eviva PSU and Veriva PPSU closely match those of human bone, such as density and modulus of elasticity, making them ideal for implant applications.
Polysulfone polymers are lightweight yet offer strength and toughness comparable to traditional metals. This is a significant advantage in applications where weight reduction is crucial without compromising durability.
Efficiency in Manufacturing with Implantable PSU and PPSU
PSU and PPSU by nature allow for easier processing compared with other materials such as metal. The amorphous nature of Eviva PSU and Veriva PPSU thermoplastics, allows for high moldability and enhanced dimensional tolerance, allowing more complex geometries in the injection molding process. This capability of polysulfones to be injection molded offers significant advantages for high-volume production, thereby reducing manufacturing costs and time by eliminating additional post-processing steps such as machining. Both PSU and PPSU also offer excellent weldability, facilitating the assembly of medical devices.
Pioneering the Future of Medical Implants
By leveraging these unique properties, Syensqo's implantable polysulfones, Eviva® PSU and Veriva® PPSU, are setting new standards in the medical implant industry. These advanced polymers provide transparency, radiolucency, excellent insulative properties, and chemical resistance. Their lightweight yet strong nature, combined with high moldability and weldability, streamlines manufacturing and reduces costs. Ideal for a wide range of medical applications, Syensqo's polysulfones are a top choice for medical implants.
