Problems solved by technology

The method of opening and clamping the leaflets of the mitral valve clip is too complicated, and it may be clamped in an incorrect position. It needs to be judged by the phenomenon after clamping. If it is not correct, the above operation needs to be repeated.
Therefore, the patent operation is complicated

Embodiment Construction

[0031] In the following description, the proximal end refers to the end close to the operator, and the distal end refers to the end away from the operator.

[0032] The invention provides a retrievable mitral regurgitation blocking device, such as figure 1 , including a fixed shaft 1, a spoiler 2 and an anchor 3.

[0033] The anchor 3 is fixed on the side of the left atrium of the mitral valve, and the blocking member 2 is fixed on the side of the left ventricle of the mitral valve to prevent blood backflow. The anchor 3 and the blocking member 2 are connected by the fixed shaft 1 . Both the anchor piece 3 and the flow blocking piece 2 have shape memory properties. During the specific operation, the anchor piece 3 and the flow blocking piece 2 are in a folded state, placed in the catheter, sent to between the mitral valves along the catheter, and the device is released to realize The anchor piece 3 is fixed on the side of the left atrium of the mitral valve, and the blocking ...

Abstract

The invention discloses a recoverable mitral valve regurgitation choking device which comprises a fixing shaft, a choking part and an anchoring part. The anchoring part is fixed at the near end of the fixed shaft, and the anchoring part has shape memory; the flow choking piece comprises a flow choking film and a supporting ring, the center of the flow choking film is fixed to the far end of the fixing shaft, the edge of the flow choking film is fixed to the supporting ring, and the supporting ring has shape memorability. The invention provides a recoverable mitral valve regurgitation choking device. The recoverable mitral valve regurgitation choking device comprises a fixing shaft, a choking part and an anchoring part. The device can enter the heart through the catheter, intervention can be carried out in a minimally invasive mode, trauma is small, and the device is relatively safe and good in curative effect.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a retrievable mitral valve regurgitation blocking device. Background technique [0002] The mitral valve is the left atrioventricular valve. Attached to the left fibrous atrioventricular ring, formed by folds of the endocardium. The mitral valve is like a "one-way valve", which ensures that the blood circulation flows from the left atrium to the left ventricle and passes through a certain flow. When the left ventricle of the heart contracts, it squeezes the blood in the chamber, and the blood hits the valve, and the mitral valve tightly closes the atrioventricular opening to prevent blood from flowing backward into the left atrium. There is an orifice of the aorta in the upper right front of the left ventricle, from which blood from the left ventricle is sent to the aorta. [0003] The mitral valve can become less effective due to congenital, inflammatory or infectious diseases,...
