Abstract

The invention provides a woven type volume reduction device which comprises a woven stent. The woven stent is formed by weaving shape memory alloy sutures in a net shape, and comprises a stent body located in the ventriculus sinister, a waist part penetrating through the cardiac apex and a lower disk face located outside the cardiac apex. The shape of the lower disc face is matched with the outer wall of the ventriculus sinister, the shape of the released stent body is matched with the inner wall of the ventriculus sinister, the side, far away from the cardiac apex, of the stent body is covered with a flow blocking film, an inner wall fixing structure is arranged on the side, far away from the cardiac apex, of the stent body in the circumferential direction, and the stent body is fixed to the inner wall of the ventriculus sinister through the inner wall fixing structure. The woven type volume reduction device improves stability and effectiveness, the volume reduction amount is adjustable, equipment loss and operation time are saved, use is easy and convenient, and popularization is easy.

Description

technical field [0001] The invention relates to a braided volume reducing device. Background technique [0002] For patients with old myocardial infarction with no or abnormal movement of the anterior wall, decreased left ventricular ejection fraction (LVEF), and ventricular aneurysm, traditional surgical left ventricular volume reduction is treated by surgical operation. [0003] In recent years, with the development of surgical methods and medical devices, percutaneous ventricular reconstruction has been popularized and clinically implemented. The main principle is to isolate the non-functional ventricular area of ​​the left ventricle, reduce the volume of the left ventricle, reduce the tension of the left ventricle, and improve the weight of the left ventricle. It can harmonize the patient's heart function, relieve heart failure, and improve the heart's pumping ability. However, due to the high elasticity / rigidity of the medical device itself, the sheath tube used to del...
