## About Ceryx Medical Ltd

Ceryx Medical Ltd is a Medtech company based in Cardiff, Wales, founded in 2016 as a spin-out from the Universities of Bath and Bristol.

The company focuses on developing bioelectronic medical devices, particularly aimed at treating heart failure. Ceryx Medical is known for its proprietary microchip technology that mimics the body's natural nerve centers, known as Central Pattern Generators (CPGs), to restore normal autonomic functions disrupted by disease or injury. The company's lead product, Cysoni, is a cardiac rhythm management device designed to improve heart function and patient quality of life by synchronizing cardiac and respiratory rhythms. Ceryx Medical is also developing Cysoni-XT, a temporary cardiac pacemaker for post-surgical recovery. With a small team and significant early-stage funding, Ceryx Medical is advancing its products toward clinical evaluations, aiming to provide innovative therapies for heart failure and other autonomic disorders.
