Abstract

The invention discloses a heart assistant device. The heart assistant device comprises a catheter and a plurality of supporting blades; each supporting blade comprises a shell and a flexible bag, wherein each flexible bag is connected with a medium pumping out-in device through a connecting tube, and arranged on the corresponding shell, and after a medium is pumped into the flexible bags, the flexible bags can swell, and at least parts of the flexible bags can be exposed outside the corresponding shells; the heart assistant device also comprises a guide mechanism and a push mechanism, whereinthe guide mechanism is used for guiding the catheter in being inserted into the pericardium, the push mechanism can drive the supporting blades to perform displacement along the catheter and stretch out of the catheter, the shells are made from memory alloy, and in the stretched state, the supporting blades can be unfolded to coat the heart or the specific ventricle. The provided heart assistant device can assist the heart or the specific ventricle in beating, thereby performing auxiliary treatment on a patient with cardiac failure to buy time for a heart transplantation operation.

Description

Technical field [0001] The invention relates to the technical field of medical devices, in particular to a heart assist device for treating heart failure. Background technique [0002] Heart failure is abbreviated as heart failure, which refers to the failure of the systolic and / or diastolic dysfunction of the heart to fully discharge the venous return blood volume to the heart, leading to blood stasis in the venous system and insufficient blood perfusion in the arterial system, thereby causing cardiac circulatory disorders. The incidence rate increases year by year with age, which seriously affects people's life safety. [0003] At present, heart transplantation is one of the most effective methods for the treatment of end-stage heart failure. It can significantly improve the survival rate of patients with end-stage heart failure. The 1-year expected survival rate can reach 85%. However, there is a shortage of heart donors and many patients Can't wait to find the right heart, and...
