Embodiment 1

[0034] Such as Figure 1-6 As shown, this embodiment provides a ventricular assist device, including a stent 1 supporting the inner wall of the ventricle, a connecting wire 2 and an anchoring structure 3 . The structure of the stent 1 is consistent with the original structure of the ventricle, and it is claw-shaped in the ventricle environment. It can fully contact the heart when used, and can contract and relax with the heart. An anchoring structure 3 is connected to the rear end of the stent 1 through a connecting wire 2 to securely fix the ventricular assist device in the ventricle. The ventricular assist device of this embodiment can be placed into the ventricle in conjunction with the matching blood vessel infusion device, and is compressed when the ventricle contracts to store energy and generate radial support force. And when the ventricle is diastolic, the radial support force is used to assist the ventricle to dilate, thereby improving heart function.

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a ventricular assist device and an application method thereof. The ventricular assist device includes astand, a connecting line and an anchoring structure, wherein the stand includes a plurality of elastic support arms and an annular support, the rears of the elastic support arms are connected to theannular edge of the annular support so as to form a claw-shaped support structure which is adapted to the ventricular structure and applied to radial support of the inner wall of the ventricle, and the anchoring structure is anchored in the ventricle; the annular support is connected with the anchoring structure through the connecting line so as to fix the stand in the ventricle, the outer sides of the elastic support arms are in contact with the inner wall of the ventricle, and the elastic support arms are compressed by force when the ventricle contracts, and restores and expands when ventricular diastole occurs. The ventricular assist device can be compressed during ventricular contraction, so that energy is stored, and a radial support force is generated; ventricular diastole is assisted through the radial support force during ventricular diastole, so that heart functions are improved; and the ventricular assist device has a simple structure and high compatibility.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a ventricular assist device and a use method thereof. Background technique [0002] The importance of abnormal diastolic function in congestive heart failure has received increasing attention in recent years. It can occur simultaneously with systolic dysfunction or it can exist alone. Diastolic heart failure is due to the impairment of the ability of the ventricle to actively relax and the reduction of the compliance of the ventricle during the diastole period, so that the filling of the ventricle in the diastole period is impaired, and the pressure-volume curve of the ventricle is shifted to the upper left, so the stroke volume is reduced, and the left ventricular Heart failure occurs due to increased end-diastolic pressure, but the ejection fraction, which represents systolic function, is normal. [0003] The mechanisms of diastolic heart failure are: ① Im...
