Adjustable curved heart intracavity defibrillation catheter with inflatable air bag at head end

Abstract

The present invention discloses an adjustable curved heart intracavity defibrillation catheter with an inflatable air bag at a head end. The adjustable curved heart intracavity defibrillation cathetercomprises a handle and an outer surface of one end of the handle is provided with a balloon syringe interface and a defibrillation electrode tail circuit interface. A bending controller can enable the defibrillation catheter to accurately reach more heart intracavity spaces and to be better attached to ventricular muscles, so that lower-energy defibrillation is realized and use of a clinician isfacilitated. A defibrillation electrode can record electrical activity of each part in heart cavity and is conductive for the clinician to judge specific positions in the heart cavity. A head end balloon prevents risks of vascular rupture caused by mistake-entering of the catheter into small blood vessels, can increase contact area of the catheter head end with the heart, prevents the catheter from puncturing cardiac muscles to lead to cardiac rupture, can realize bedside blind sending of the defibrillation catheter into the heart cavity, reduces harms of X rays to body health, shortens rescuetime consumed by going to a heart catheter chamber, and can best master the best rescue time for patients.

Description

technical field [0001] The invention relates to the field of low-energy electrical cardioversion or electrical defibrillation during cardiac intervention or heart rescue, in particular to an adjustable curved intracardiac defibrillation catheter with an inflatable air bag at the head end. Background technique [0002] Intracardiac defibrillation catheter is a catheter for low-energy electrical cardioversion or defibrillation during cardiac intervention or heart rescue. Its low-energy output can significantly reduce the pain of patients during electrical defibrillation, and it has been gradually applied to clinical treatment. , but the controllability and safety of the existing intracardiac defibrillation catheters need to be improved. [0003] During use, the intracardiac defibrillation catheter can complete the following operations: use low energy for electrical cardioversion or electrical defibrillation during cardiac interventional surgery or heart rescue.

Problems solved by technology

[0004] Although the existing intracardiac defibrillation catheters are simple in structure and easy to use, their design needs to rely on X-rays to guide catheter placement, and are suitable for electrical cardioversion or defibrillation during interventional operations in the cardiac catheterization laboratory. Inconvenient operation during heart rescue limits the widespread use of intracardiac defibrillation catheters. The head end of the curved catheter can form an inverted "U" structure, which can be more closely attached to the myocardium to achieve lower energy electrical cardioversion or defibrillation. During the process, it is easy to stray into small branch blood vessels, resulting in the danger of blood vessel rupture. After being sent into the heart chamber, the electrode tip may break through the myocardium without the protection of the balloon and cause the risk of heart rupture. Therefore, we propose a tip belt that can Inflatable Balloon Intracardiac Defibrillation Catheter with Adjustable Bend
