Evonik launches implant-grade PEEK filament for medical applications in 3D printing

, /in /by

Evonik is the first company in the world to launch a 3D-printable PEEK (polyether ether ketone) filament as an implant-grade material for medical applications. In so doing, the specialty chemicals company is setting new standards for developing and manufacturing custom-made plastic implants, which can now be created using additive manufacturing processes that meet the requirements of ASTM F2026 (the standard specification for PEEK polymers for surgical implant applications).
Sold under the brand name VESTAKEEP i4 3DF, this PEEK filament is an implant-grade material based on VESTAKEEP i4 G, a highly viscous, highperformance polymer from Evonik. The company says customers will be impressed by the product’s biocompatibility, biostability, x-ray transparency, and easy handling. The filament is produced under cleanroom conditions and then subjected to stringent quality management standards for medical materials.
The high-performance material was developed for fused filament fabrication (FFF) technology. The natural-coloured PEEK filament, which has a diameter of 1.75 mm, is wound on 250- or 500-gram spools suitable for direct use in standard FFF 3D printers for PEEK materials. “For modern medical technology, the development of our first 3D-printable implant material opens up new opportunities for customizing patient treatments. Orthopaedics and maxillofacial surgery are examples of areas where this could be applied,” says Marc Knebel, who heads the Medical Devices & Systems market segment at Evonik.
In addition to its implant grade, Evonik is also offering a testing-grade version of its PEEK filament. The term refers to a class of material having the exact same product properties as the implant grade, but without the documentation needed for approval in medical technology applications. This offers a cost-effective way of adapting the processing characteristics of the high-performance plastic to a given 3D printer.
For more than 20 years, Evonik has been the world’s leading manufacturer of high-performance polymers and additives used in additive manufacturing. In addition to VESTAKEEP i4 3DF, the portfolio includes the RESOMER line of bioresorbable filaments, powders and granules for implantable medical devices.

Vital signs devices help early detection and response to patient deterioration in general care

, /in /by

Research suggests that the signs and symptoms of clinical deterioration can be detected as early as six to eight hours before an event or arrest. However, physiological signs and symptoms of clinical deterioration can be difficult to detect in early stages. The use of early warning scores—especially automated scores, as opposed to manual calculations—has been shown to improve effectiveness. Welch Allyn Connex vital signs devices can help hospitals combine vital signs measurement with the collection of additional patient observational information—all in a single workflow. Vital signs and additional collected information are automatically calculated to generate an overall patient score—directly on the device at the bedside. Clinicians are prompted with messages providing specific response actions based on the patient score and the facility’s protocols. Complete information can then be sent directly to the patient’s record in the EMR. The use of automated early warning scores, such as those featured in Welch Allyn Connex vital signs devices, can help provide the timely decision support clinicians need to respond to patient changes right at the bedside.

Ultrasound system powered by artificial intelligence

, /in /by

GE Healthcare’s new generation of high-end fully digital radiology ultrasound system, the LOGIQ E10, integrates artificial intelligence technology, cloud connectivity, and advanced algorithms to acquire and reconstruct data faster than ever before. As a result, it enables confident diagnosis with comprehensive tools and concise workflow. 
Artificial intelligence technology is now used in this ultrasound system’s platform – the cSound Architecture. This advanced GPU hardware technology acquires and reconstructs data in a similar way to an MRI or CT system, enabling 48 times the data throughput and 10 times the processing power of previous systems. The cSound Architecture is so powerful that it can process an amount of data equivalent to playing two entire DVDs in just one second, in real-time. The system eliminates the need for focal zones, as the entire image is always in focus throughout the exam.
With hospital systems growing and expanding their geography, many ultrasound exams are now read by a clinician not on site. The new Photo Assistant App enables users to photograph relevant anatomy and include the photos with the clinical images sent to the radiologist, providing valuable context and documentation. Another tool – called remote clinical application – allows radiologists to manipulate the ultrasound’s settings with a remote control on their tablet or smart phone. Clinicians can also analyse how the system is being used with a web-based secure portal or get assistance remotely. Providing a new way for clinicians to connect with their colleagues and patients, Tricefy from Trice Imaging adds cloud-based image sharing, diagnostic collaboration, remote viewing, archiving and Electronic Health Record (EHR) integration.
