Embodiment 1

[0039] Such as figure 1 , 2 As shown, the left ventricular volume reduction device of the present invention adopts a two-stage design, which are the main body 13 and the base 14 respectively. The main body 13 is integrally formed by laser cutting of a nickel-titanium alloy tube, and the nickel-titanium alloy tube used has anti-magnetic properties and does not affect nuclear magnetic resonance imaging. Its cage-like structure has excellent mechanical stability, is not easy to deform, break and fall apart, and maintains its structural integrity. Such as figure 2 As shown, the left ventricular volume reduction device involved in the present invention can be placed in the left ventricle 1 through the aorta or through the apex, the base 14 is located at the position of the left apex 8, and the main body 13 is attached to the outer wall of the left ventricle 1 and the interventricular septum 3 Placed above the base 14, isolate the inactivated myocardium below the left ventricle ...

Embodiment 2

[0042] Such as Figure 5 , 6 , 7a, 7b, and 7c, this embodiment adopts a three-stage design, which are the main body 16, the base 17 and the blocking disc 18 respectively. The main body 16 is integrally formed by laser cutting of a nickel-titanium alloy tube, and the nickel-titanium alloy tube used has anti-magnetic properties and does not affect nuclear magnetic resonance imaging. Its cage-like structure has excellent mechanical stability, is not easy to deform, break and fall apart, and maintains its structural integrity. The left ventricular volume reduction device involved in the present invention can be placed in the left ventricle 1 through the aorta or through the apex, the occlusion disc 18 is placed outside the myocardium of the apex of the left ventricle, the base 17 is located at the position of the left apex 8, and the main body 16 is placed above the base against the outer wall of the left ventricle 1 and the interventricular septum 3 to isolate the inactivated m...

Embodiment 3

[0045] Such as Figure 8 and Figure 9 As shown, the left ventricular volume reduction device of the present invention adopts a two-stage design, which are the main body 13 and the base 14 respectively. The main body 13 is integrally formed by laser cutting of a nickel-titanium alloy tube, and the nickel-titanium alloy tube used has anti-magnetic properties and does not affect nuclear magnetic resonance imaging. Its cage-like structure has excellent mechanical stability, is not easy to deform, break and fall apart, and maintains its structural integrity. Such as figure 2 As shown, the left ventricular volume reduction device involved in the present invention can be placed in the left ventricle 1 through the aorta or through the apex, the base 14 is located at the position of the left apex 8, and the main body 13 is attached to the outer wall of the left ventricle 1 and the interventricular septum 3 Placed above the base, it isolates the inactivated myocardium below the lef...

Abstract

The invention discloses a left ventricle volume reduction device. Two-section design is adopted. The left ventricle volume reduction device comprises a base and a body. The base is of a cage structure. The body is formed by conducting laser cutting on a whole nickel-titanium alloy tube and designed in multiple layers of meshes. The meshes are designed into a closed-loop structure, the top end of the body is provided with anchor thorns inclining upwards, in the placing process, the anchor thorns can prick into the cardiac muscle of the left ventricle wall, the effect of anchoring the left ventricle volume reduction device is achieved, the lower end of the body is connected with a tubular structure, the tubular structure is connected with the base, and the base is woven into a woven mesh structure through nickel-titanium wires and thermally treated into a disc shape. The left ventricle volume reduction device can be repeatedly positioned and is stable in fixation.

Description

technical field [0001] The invention relates to the technical field of left ventricular volume reduction devices, in particular to a repositionable, fixed and stable left ventricular volume reduction device. Background technique [0002] Heart failure is a common debilitating and potentially fatal condition in which the heart cannot provide enough blood flow to meet the body's needs. Symptoms of heart failure that negatively affect quality of life include shortness of breath, persistent coughing or wheezing, excessive fluid buildup in body tissues (edema), fatigue, loss of appetite or nausea, slowed thinking, and rapid heart rate. In recent years, the prevalence of heart failure has increased year by year and has become a serious public health problem. It is reported that 17 million people die of cardiovascular disease in the world every year, and more than half of them die of acute myocardial infarction. Even if patients survive, they are prone to develop chronic diseases. ...
