Abstract

The invention provides a medical device helpful to improve the effectiveness and stability of anchoring in myocardial fixation and improve the effect of myocardial tightening. The medical device includes a first implant for making contact with a first wall of an implanted object, a second implant for making contact with a second wall of the implanted object, and a tightening mechanism for being connected with the first implant; the tightening mechanism passes through a locking mechanism, the locking mechanism is in cooperative connection with the tightening mechanism, and the second implant can move in a direction approaching the first implant along the tightening mechanism. The second implant can move in the direction away from the first implant along the tightening mechanism when the tightening mechanism and / or the locking mechanism are deformed.

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...
