The occluder is a stroke prevention device designed to be permanently implanted at the opening of the LAA of patients with non-valvular atrial fibrillation (AF) to prevent thrombus escaping from the LAA, thus causing embolization.
The left ventricular assist system (LVAS) can partially replace ventricular pumping function and provide stable hemodynamic support for patients with insufficient cardiac transfusion function. Prevent myocardial infarction and avoid myocardial damage (irreversible).
Cryoballoon catheter was used with cryoablation apparatus.Through atrial septal puncture, the balloon type cryoablation catheter was placed at the entrance of pulmonary vein through sheath tube, and the pulmonary vein potential was isolated by injecting cryogen into the balloon, so as to treat atrial fibrillation originated from pulmonary vein.
The equipment houses the components and software needed to perform cryoablation procedures. It controls the delivery and disposal of cryoablation refrigerant safely and efficiently.
The device is intra-cardiac electrophysiology diagnostic catheter, which allow for the assessment of pulmonary vein isolation during the cryoablation procedure. The catheter is deployed through the cryoballoon guide wire lumen, minimizing the number of catheter exchanges and allowing the procedure to be performed using a single transseptal puncture. The catheter may also provide recording of real-time PV potentials during cryoablation with the cryoballoon.
The device delivers a refrigerant through an inflatable balloon to freeze tissue and disable unwanted electrical signals that contribute to AF originated from pulmonary vein.
The sheath is a unidirectional, deflectable sheath used to help position an ablation catheter and facilitates better positioning and maneuverability in coronary artery and chamber and peripheral artery
The pulsed feld ablation system is used with the pulse ablation catheter ,to provide energy for the ablation catheter and reach the target ablation area for the treatment of symptomatic paroxysmal atrial fibrillation.
