Embodiment 1

[0042] Such as Figure 1-5As shown, the left ventricular volume reduction device of the present invention adopts a two-stage design, which are the main body and the base 14 respectively. The main body is divided into an outer body layer 13 and an inner body layer 12. The outer layer of the main body is formed by integral laser cutting of a nickel-titanium alloy tube. The nickel-titanium alloy tube used has anti-magnetic properties and does not affect nuclear magnetic resonance imaging. The structure of the main body has excellent mechanical stability, is not easy to deform, break and fall apart, and maintains its structural integrity. The left ventricle volume reduction device involved in the present invention can be placed in the left ventricle through the aorta or through the apex. The base 14 is located at the bottom of the left apex. Inactive myocardium beneath the ventricle reduces left ventricular volume, predisposes the heart to further enlargement, and reduces wall te...

Embodiment 2

[0045] Such as Figure 6-9 As shown, the left ventricular volume reduction device of the present invention adopts a two-stage design, which are the main body and the base 14 respectively. The main body is divided into an outer body layer 13 and an inner body layer 12. The outer layer of the main body is formed by integral laser cutting of a nickel-titanium alloy tube. The nickel-titanium alloy tube used has anti-magnetic properties and does not affect nuclear magnetic resonance imaging. The cage-like structure of the main body 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 through the aorta or through the apex, the base 14 is located at the left apex, and the main body is placed above the base against the outer wall of the left ventricle and the interventricular septum to isolate the left ve...

Embodiment 3

[0048] Such as Figure 10 , 11 As shown, the left ventricular volume reduction device of the present invention is based on the second embodiment, and the outer layer 13 of the main body is connected to the base 14 . The base 14 is laser-cut with a nickel-titanium tube, bent into a shape after heat treatment, and a plurality of rods or interconnected rods converge to one end to connect with the main body. A PFTE or PET flow-blocking film can be sewn under the base 14 .

[0049] The left ventricular volume reduction device of the present invention can be connected with the bolt head of the delivery rod through the steel sleeve 20 . When the delivery rod is pushed, the delivery rod applies force to the inner layer of the main body of the left ventricular volume reduction device, and the left ventricular volume reduction device is pushed to a proper position inside the left ventricle through the catheter through the apex. When recovering, the pulling force of the connection of t...

Abstract

The invention discloses a left ventricular volume reduction device, which includes: a main body and a base. The main body includes a main body outer layer and a main body inner layer. The main body outer layer is made of a nickel-titanium alloy tube that is laser cut, heat-treated, and polished into a cup shape. ; The lower end of the outer layer of the main body is a closed-loop structure, which is conducive to release and expansion. The upper end of the outer layer of the main body is a plurality of support rods. The ends of the support rods are provided with a hole for connecting the inner layer of the main body, and The inner layer of the main body is knitted with nickel-titanium wires, and the nickel-titanium wires are connected through the holes. The two ends of the nickel-titanium wires are knitted and gathered at the bottom of the inner layer of the main body, and are in the main body. A steel sleeve is provided at the bottom of the layer, and the steel sleeve is used to connect the bolt head of the conveying rod. The grids under the outer layer of the main body converge into a tubular structure, and the tubular structure is connected to the base. The invention is a repositionable, fixed and stable left ventricular volume reduction device.

Description

technical field [0001] The invention relates to the technical field of left ventricle volume reduction, in particular to a repositionable, fixed and stable left ventricle 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. heart failu...
