AI Technical Summary

Technical Problem

The existing pulsed field ablation devices lack dedicated treatment equipment for hypertrophic cardiomyopathy, which makes the operation complex, difficult to promote widely, and poses a risk of damage to normal myocardial conduction bundles.

Method used

A specialized device for pulsed field ablation therapy of hypertrophic cardiomyopathy was designed. It adopts a dual-catheter push-pull release elastic circular radial magnetic suction design, combined with a sterilization sleeve and heating element, to ensure precise positioning and disinfection of the ablation area and simplify the operation process.

Benefits of technology

This technique enables precise nanoscale perforation ablation of hypertrophic myocardium, avoiding ventricular septal rupture and damage to normal myocardium, improving surgical safety and ease of operation, and promoting the widespread application of pulsed field ablation therapy.
