Problems solved by technology

Once the heart function deteriorates, the self-beating ability decreases so that the ventricular contractility cannot overcome the aortic pressure formed by the axial flow pump auxiliary system, the ventricle stops bleeding, and the arterial blood pressure is completely expressed as non-pulsating pressure, and life is difficult to maintain
In addition, when the axial flow pump system runs at high speed and high flow rate, it is more destructive to the formed components of blood, which is not suitable for physiological needs, and it is difficult to maintain long-term use

Embodiment Construction

[0066] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, in which the same reference numerals indicate the same or similar elements throughout. The embodiments described below with reference to the drawings are exemplary, and are intended to explain the present invention, but cannot be construed as a limitation to the present invention.

[0067] image 3 It is a schematic diagram of the heart beat assist device in an expanded state according to the first exemplary embodiment of the present invention. The heart beat assist device is indicated by the reference numeral 10. The heart beat assist device 10 can be implanted in whole or in part in the enlarged ventricle of a patient with heart failure to assist in the treatment of heart failure. It includes a supporting device 11 having an internal shape and a heart apex of the heart ventricle. A concave structure that is basically compatible with...

Abstract

The invention provides a cardiac impulse assist device. The cardiac impulse assist device at least can be partially implanted into the inner side of a ventricle, and is used for treating cardiac failure. The cardiac impulse assist device comprises a supporting device and a retractable device, wherein the supporting device has a concave structure which basically adapts to the internal shape of theventricle or the shape of a body cavity outside a heart, so as to be entirely or partially implanted into the ventricle; and the retractable device is partially accommodated in the concave structure of the supporting device, and operatively has a dilation state in which the retractable device can be dilated out from the concave structure and a retraction state in which the retractable device retracts from the dilation state to the concave structure, so as to synchronously change blood storage volume and pressure of the ventricle with cardiac impulse. The invention also provides a cardiac impulse assist system and a method for treating and monitoring the cardiac failure.

Description

Technical field [0001] The present invention relates to a heart beat assist device for the treatment of heart failure, in particular to a heart beat assist device that can be at least partially implanted in the heart, and a heart beat assist system including the heart beat assist device, and A method for treating heart failure using this heart beat assist device. Background technique [0002] Heart failure is a syndrome caused by cardiac insufficiency caused by various cardiovascular diseases. The reason is that the decrease in myocardial contractility causes the stroke volume to not meet the body's metabolic needs. At the same time, blood stasis in the heart increases the pressure in the heart cavity during diastole and expands the heart cavity, further reducing myocardial contractility and aggravating heart insufficiency, resulting in obstruction of blood return to systemic and pulmonary circulation, causing circulatory dysfunction and metabolic disorders. When heart failure ...
