Instrument for slowing down heart failure through percutaneous intervention

Abstract

The invention relates to the technical field of medical instruments, in particular to an instrument for slowing down heart failure through percutaneous intervention. The instrument comprises a catheter and a guide wire body, the surface of the guide wire body is movably sleeved with the catheter, a mounting groove is formed in the surface of the catheter, a supporting airbag is arranged in an inner cavity of the mounting groove, and an interventional stent is arranged on the surface of the supporting airbag. According to the instrument for slowing down heart failure through percutaneous intervention, through cooperative use of the mounting groove and arc-shaped rings, the mounting groove is formed in the surface of the catheter, the supporting airbag is mounted through the mounting groove,and meanwhile the arc-shaped rings are mounted at the positions, located on the two sides of the mounting groove, of the surface of the catheter so that the protruding height of the surface of the catheter can be effectively reduced when the catheter is guided in, meanwhile, the arc-shaped rings can be used for preventing the two sides of the interventional stent from stimulating and scratching the inner wall of a blood vessel, and the stability of the instrument for slowing down heart failure through percutaneous intervention is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device for slowing heart failure through percutaneous intervention. Background technique [0002] Heart failure, referred to as heart failure, refers to the failure of the venous blood to fully discharge the heart due to cardiac systolic and / or diastolic dysfunction, resulting in blood stasis in the venous system and insufficient blood perfusion in the arterial system, resulting in cardiac circulation syndrome. , This kind of disorder symptom group manifests as pulmonary congestion and vena cava congestion. Heart failure is not an independent disease, but the end stage of the development of heart disease. The vast majority of heart failure starts with left heart failure, that is, it first manifests as pulmonary circulation congestion, and almost all cardiovascular diseases will eventually lead to heart failure, myocardial infarction, cardiomyopathy, and hemodynamic ove...

Problems solved by technology

[0003] However, when the traditional catheter is used, the support balloon and the interventional stent are located on the surface of the catheter, so that the protruding position of the catheter surface is high and the bumps are large, which will cause pressure on the patient's fragile blood vessels when it is introduced. Generally, only one interventional stent can be placed at a time, and many patients have more than one lesion in the blood vessel, which requires multiple treatments, which not only wastes medical equipment, but also increases the treatment cost of the patient and increases the pain borne by the patient. , so we propose a device for percutaneous intervention to relieve heart failure
