Embodiment Construction

[0050] The core idea of ​​the present invention is to provide a medical device, which is mainly used for myocardial fixation, and by intervening one or more pairs of anchors to treat anterior wall necrosis and non-contractile myocardium, so as to restore the geometry of the left ventricle and function.

[0051] In order to make the purpose, advantages and characteristics of the present invention clearer, the following in conjunction with the attached Figure 1~7b The medical device proposed by the present invention is further described in detail. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0052] As used in this specification, the singular forms "a", "an" and "the" include plural referents unless the content clearly dictates otherwise. As used in this specification, the term "or" is generally employed ...

Abstract

The invention provides a medical device. The medical device benefits reduction of the size of a transportation structure, so that damage of the transportation structure to tissues is reduced, and theintensity and the effectiveness of cardiomyopexy can be improved. The medical device comprises an inner anchor log, an outer anchor log and a tightening mechanism; the inner anchor log is used for being in contact with a first wall of an implantation object, and the outer anchor log is used for being in contact with a second wall of the implantation object; the tightening mechanism is connected with the inner anchor log, and penetrates through the outer anchor log, the outer anchor log is connected with the tightening mechanism in a matched mode, and the outer anchor log can move along the tightening mechanism to get close to the inner anchor log; and specially, both the inner anchor log and the outer anchor log are self-adaption elastic structures, and the self-adaption elastic structurescan be compressed to a first size in a first environment, and can expand to a second size in a second environment.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical device for adjusting myocardial shape. Background technique [0002] Heart failure is the terminal stage of most cardiovascular diseases. Although the application of heart failure drugs in the past 20 years has obviously benefited heart failure patients, the mortality rate of end-stage heart failure patients is still high. The pathophysiological basis of heart failure is cardiac remodeling. Cardiac remodeling, manifested clinically by progressive ventricular dilation and impaired systolic and diastolic function, is associated with progressive heart failure and increased mortality. [0003] Currently recommended angiotensin-converting enzyme inhibitors (ACEIs) / angiotensin II receptor antagonists, beta-blockers, aldosterone receptor antagonists, and cardiac resynchronization therapy (CRT) can slow down or reverse the left Ventricular remodeling improves clinica...
