Embodiment Construction

[0048] In order to make it easy to understand the technical means, creation features, achieved goals and effects of the present invention, the present invention will be further described below with reference to specific drawings.

[0049] In the field of interventional medical devices, the "distal end" is defined as the end away from the operator during the operation, and the "proximal end" is defined as the end close to the operator during the operation.

[0050] In the present invention, unless otherwise expressly specified and limited, terms such as "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense, for example, it may be a fixed connection or a detachable connection , it can also be integrated; it can be a mechanical connection, an electrical connection, or a communication connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two comp...

Abstract

The invention discloses a recoverable inner anchor for a left ventricular volume reduction device and the left ventricular volume reduction device. The inner anchor is provided with a contact surface capable of abutting against a right ventricular septum; the non-contact surface is opposite to the contact surface, at least one side edge of the non-contact surface extends towards the direction of the middle of the non-contact surface to form a barb which is approximately parallel to the non-contact surface, and a space between the barb and the non-contact surface forms a guide cavity which can provide guidance for the snare. The barbs are arranged on the non-contact surface of the inner anchor, the snare can be hung on the barbs, so that when an operation fails or the inner anchor needs to be taken out subsequently, the snare only needs to be hung on the barbs on the inner anchor, the inner anchor is pulled out of the body from the conveying sheathing canal, thoracotomy operation is not needed, the secondary intervention recovery function is achieved, and the operation is convenient. The error-tolerant rate of the operation is increased, the economic burden of the patient is relieved, and high-risk operations such as open-heart operations are avoided.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a recoverable inner anchor for a left ventricular volume reduction device and a left ventricular volume reduction device. Background technique [0002] During a heart attack, the delivery of blood, oxygen and nutrients is blocked. This causes the heart tissue to slowly die, and parts of the beating muscle are replaced by inert scar tissue. After a heart attack, the heart enlarges for a short period to keep blood flowing and keep a person alive, but over time scar tissue begins to weigh on the heart and weaken the heart muscle. Common interventions such as coronary stenting and drug therapy do not solve this problem. The Left Ventricular Volume Reduction Device is a transcatheter ventricular augmentation system that can be used to address scar tissue in patients with ischemic cardiomyopathy after myocardial infarction. It embeds a series of anchors into the ...
