KRAIBURG TPE supplies custom-colored medical-grade thermoplastic elastomer for Nerivio, a novel wireless neuromodulation wearable from Theranica for drug-free acute treatment of migraine.

 

The device has passed clinical testing, is FDA-authorized and conforms to all applicable IEC/EN 60601 standards for medical devices, and nerve stimulators. The TPE material provides ISO 10993 certified biocompatibility and is supplied in line with new VDI 2017 guidelines.

 

It is worn on the arm and uses electronic pulses for inducing a drug-free pain inhibition mechanism. The user-friendly app is available for both Android and iOS smartphones and includes a migraine diary that can be shared with healthcare professionals, for better managing this disabling disease.

KRAIBURG TPE supplies custom-colored medical-grade thermoplastic elastomer for Nerivio.


“For the outer layer of the Nerivio, we tested a variety of different biocompatible materials to find the best combination of soft feel, certified dermatological tolerance, processability and surface quality,” says Alon Ironi, President & CEO of Theranica. “Furthermore, the compound had to provide long-term adhesion to double-sided sealing tape, without delamination.”

 

In close cooperation with AiT Chemicals, a leading local supplier of polymers and KRAIBURG TPE’s distributor in Israel, Theranica selected a THERMOLAST M medical-grade thermoplastic elastomer (TPE) that offered the property profile for this device.

 

It delivers a smooth and velvety surface ‘as molded’, with durable abrasion resistance to the securing armband and strap of the device. It is biocompatible and offers irritation-free characteristics while meeting cytotoxicity requirements.

 

The compound is pre-colored ex works to match the stylish grey surface texture of the armband according to customer requirements. Also, many of KRAIBURG TPE’s portfolio compounds are documented in FDA Drug Master Files. This helps the end customers to speed up regulatory approvals and time-to-market.

 

“Thanks to our long-standing partnership with AiT Chemicals and our early inclusion in this application project, we were able to supply a custom-tailored TPE that meets all the specifications and requirements of Theranica, from ease of processing to biocompatibility and color,” says Oliver Kluge, Advisor for Medical Products at KRAIBURG TPE.

 

Following comprehensive clinical clearance, the Nerivio device received a De Novo approval from the U.S. Food and Drug Administration (FDA) for clinical use in May 2019. The FDA classified the wearable as a trunk and limb electrical stimulator to treat headache. It conforms to all applicable IEC/EN 60601 standards for the safety and electromagnetic compatibility of medical electrical equipment, nerve, and muscle stimulators.

 

In the United States, Nerivio is already available as a prescribed wearable, including through telemedicine platforms UpScript and Cove. It is expected to be launched in Europe and other regions in 2021.
