Pulsating catheter device assisting function of left ventricle

Abstract

The invention discloses a pulsating catheter device assisting the function of the left ventricle. The device comprises an executing part and a control module, wherein the executing part comprises a balloon capable of realizing inflating and deflating, a bracket and an artificial valve, the bracket is positioned at one end of the balloon, the artificial valve playing the role of the valve is arranged in the bracket, the balloon is externally connected with a ventricle assisting catheter pump through an air guide pipe, the control module is positioned in the ventricle assisting catheter pump, and the executing part is controlled by the control module and is adaptive to the pulsating property of the heart of a patient, so that the blood of the left ventricle is lifted to the aorta. For the minimally invasive catheter type synchronous heart assisting device provided by the invention, the blood of the left ventricle of the patient can be promoted to the aorta, so that an obvious effect canbe achieved on resuscitation after the cardiovascular surgery of the patient, the heart transplantation transition or replacement, the recovery of the myocardial function and even the perpetual treatment for cardiac failure, meanwhile, the manufacturing cost is low, the structure is simple and compact, and the popularization and promotion are convenient.

Description

Technical field: [0001] The invention relates to the field of cardiac assisted circulation, in particular to a pulsating catheter device for assisting left ventricular function. Background technique: [0002] Heart failure is a disease that seriously threatens human life. About 1 / 5 of heart disease patients in the world will eventually develop heart failure every year. At present, the incidence of heart failure in my country is 0.9% and the 5-year mortality rate exceeds 60%. When traditional drug therapy has certain limitations and cannot achieve satisfactory results, and heart transplantation is facing difficulties such as lack of donors and postoperative rejection, researchers have proposed a method of using mechanical devices to help the heart recover and developed a ventricular assist system. device. Since its clinical application in the 1960s, after years of research and clinical application, the application of ventricular assist devices has expanded from resuscitation...

AI Technical Summary

Problems solved by technology

[0004] However, the domestic third-generation ventricular assist device is implantable and non-pulsatile, which requires surgical implantation to cause relatively large trauma, and does not conform to the physiological characteristics of the human body's own pulsatile nature.
