Recently, three independently developed products of Hangzhou Korigin Medical Devices Co., Ltd., a subsidiary of Mednovo Medical Group, namely Cryoablation Console (Registration Certificate No.: National Medical Device Registration 20263010555), Mapping Catheter (Registration Certificate No.: National Medical Device Registration 20263070547) and Cardiac Cryoablation Catheter (Registration Certificate No.: National Medical Device Registration 20263010651), have been granted Class III medical device registration certificates approved by the National Medical Products Administration (NMPA). This marks another milestone for Mednovo Medical Group in the field of cardiac electrophysiology!
Up to now, the Group has obtained a total of 53 medical device registration certificates.
1、Cryoablation
Cryoablation uses low-temperature freezing technology to destroy abnormal conduction pathways in the atria, thereby eliminating lesions of atrial fibrillation. Its principle is to form ice crystals in tissue cells, cause cell dehydration and electrolyte disturbance through cryotherapy (usually below -40°C), which leads to cell death and blocks the conduction of abnormal electrical activities.
It is applicable for paroxysmal/persistent atrial fibrillation, atrioventricular nodal reentrant tachycardia and other diseases, and is a very mature, safe and widely used treatment technology in the field of cardiac electrophysiology at present.
2、Cryoablation Console

The newly approved Cryoablation Console (National Medical Device Registration 20263010555) is used together with the Balloon Cryoablation Catheter produced by the Company for the treatment of drug-refractory, recurrent and symptomatic paroxysmal atrial fibrillation in adult patients.
Mapping Catheter (National Medical Device Registration 20263070547) is used together with the Balloon Cryoablation Catheter produced by the Company, connects to the electrophysiology recorder through an extension cable, and is used to record pulmonary vein potential signals during electrophysiological examination of atrial fibrillation.
Cardiac Cryoablation Catheter (National Medical Device Registration 20263010651) is used together with specific models of Cryoablation System produced by the Company for the treatment of drug-refractory, recurrent and symptomatic paroxysmal atrial fibrillation in adult patients.
The cryoablation system also includes the Steerable Sheath (National Medical Device Registration 20253030257), an approved product of the Group, which can deliver the ablation catheter into the left heart through the interatrial septum and assist catheter positioning via the control handle.
