In recent years, ablation therapy has made great progress as a treatment for ventricular tachycardia associated with organic heart disease. Ablation can reduce ventricular tachycardia load and ICD discharge, with a success rate of 70% for ischemic cardiomyopathy and a recurrence rate of 11%-37%. As our understanding of the mechanisms of ventricular tachycardia deepens and mapping and ablation techniques continue to develop, ablation therapy has become an increasingly important treatment option. The cardiac ablation catheter is a crucial tool in this therapy, and this article will provide an introduction to its use.

Composition of cardiac ablation catheter  

This product is a cardiac ablation catheter and connecting tail used in cardiac ablation procedures. The catheter is a flexible, insulated catheter with an adjustable bent head. It consists of a main catheter made of thermoplastic elastic material, a plurality of platinum-iridium alloy electrodes for delivering energy to the heart tissue, and a control handle. A thermocouple type temperature sensor is embedded in the terminal electrode to monitor the temperature of the tissue during ablation. The catheter can be bent into various specifications to suit the needs of the procedure and is available in both ordinary and hardened types. The connecting tail is a cable with multi-pin connecting plugs at both ends, made of copper wires and silicone rubber. The product is sterilized by ethylene oxide and is designed for single use.

Application of cardiac ablation catheter

Cardiac ablation catheter is mainly used for the diagnosis and treatment of arrhythmia. This product has an adjustable bent head to meet the needs of the various parts of the heart. It is composed of a fully woven composite outer tube with good biocompatibility and a plurality of precious metal electrodes. It is used for electrophysiological mapping and ablation of the heart. The tissue contacted by the head electrode of the radiofrequency catheter with the heart cavity is heated by radiofrequency waves, so as to eliminate abnormal conductive tissue and treat arrhythmia.

Strength of cardiac ablation catheter  

(1) Easy to control: 1:1 torque response, realizing fast top placement, and reducing placement difficulty to a greater extent.

(2) Sticking stability: Better head-end sticking, bending 16 strands of steel wire to weave the pipe body, improving the sticking stability in all directions.

(3) Accurate bending control: bending control is continuous, making it easier to find and stick to the target.

(4) Comfortable handle: The handle is ergonomically designed, making pushing more comfortable and labor-saving.

(5) Equipment compatibility: The extension cable is designed with multiple interfaces and is suitable for equipment with different interfaces.
