Abstract

The invention provides a medical device which does not need an additional tightening structure and a separation structure for cutting the tightening structure. The easiness for doctors to operate likeinstruments is improved, and the operation time is shortened. The medical device includes a first fixing piece including a first portion and a second portion which are connected, the first portion isused for contacting with a first wall of an implanted object, the second fixing piece comprises a third portion and a fourth portion which are connected, the third portion is used for connection withthe second portion, and the fourth portion is used for contacting with a third wall of the implanted object; when the third portion is separated from the second portion, the implanted subject is in afirst state, and the implanted subject is in a second state when the third portion is connected to the second portion.

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...
