A cooling balloon for esophageal protection in radiofrequency ablation of atrial fibrillation

Abstract

The invention discloses a cooling perfusion bag, which comprises a flexible pipeline, wherein the flexible pipeline is coiled by taking an open end of the flexible pipeline as the center to form hollow-square-shaped coil pipes; and intervals are arranged between pipelines of the hollow-square-shaped coil pipes. The flexible pipeline is coiled to form a plurality of hollow-square-shaped coil pipes. When the cooling perfusion bag is used, the safety and the simplicity are realized, and non-invasive operation is conducted, and is similar to a commonly used nasal feeding tube implantation process in clinic; the economy and the practicality are realized: since a silica gel material is adopted, the cost is low, and patient burdens and societal medical fee expenditures are not increased; and the cooling perfusion bag is additionally provided with a temperature probe, the local temperature of the esophagus can be monitored in real time, and a cross-shaped pointer is located on the back wall of the left atrium, has important iconographical reference value for atrial septum puncture, which is a key step in an operation, and manifests as identifiable iconographical characteristics when being projected in different body positions, so that the cooling perfusion bag has multiple gains in medical and scientific research uses.

Description

technical field [0001] The invention relates to a cooling perfusion bag, which belongs to the technical field of atrial fibrillation catheter radiofrequency ablation treatment. Background technique [0002] Atrial fibrillation is the most common clinical chronic arrhythmia, accounting for about one-third of all arrhythmias. The risk of embolism (including stroke), heart failure and death is significantly increased, and it is one of the main causes of death and disability. Drug therapy is ineffective, and difficulty in maintaining normal sinus rhythm is the main bottleneck in the field of drug therapy; in terms of non-drug therapy, catheter radiofrequency ablation is a radical operation for atrial fibrillation. With the advancement of technology, catheter ablation of atrial fibrillation has become more and more accepted by patients and doctors. The number of operations has increased year by year, and its safety and effectiveness have also increased steadily with the accumula...

AI Technical Summary

Problems solved by technology

[0004] 1. Strictly control the energy and temperature of the left atrial posterior wall ablation (sacrificing the curative effect);

[0005] 2. Intracardiac ultrasound monitoring and guidance (complicated procedures, expensive);

[0014] 2. The procedure is complicated and expensive: if intracardiac ultrasound is used, the operation complexity is increased, the equipment is expensive, and it is rarely used in China;

[0015] 3. Sacrificing curative effect: Controlling the ablation of the left atrium posterior wall will make some patients unable to obtain real pulmonary vein vestibular isolation, leaving hidden dangers for disease recurrence;

[0016] 4. Device defects: the esophageal probe can only be used for monitoring and cannot play a therapeutic role
