An artificial chord device, threading element and kit

Abstract

The invention discloses an artificial chordae tendineae device and a threading element and suite. The artificial chordae tendineae device comprises a flexible rope. The flexible rope is an annular rope. A first end, a second end and a third end are formed between the annular rope and the threading element. The second end and the third end are fixedly knotted to first tissue. The third end is fixed on second tissue through a traction element. The connection manner of the artificial chordae tendineae device is achieved through self-knotting in the heart, the threading element penetrates the first tissue in the third end area, pulls the first end and loosens the second end, the threading element returns to an original position, the first end is driven to penetrate the third end, self-knotting is achieved, and chordae tendineae is pulled to be fixed at the second tissue.

Description

technical field [0001] The invention provides an artificial chord device, a passing element, a kit and a method for connecting tissues with an artificial chord. Background technique [0002] An artificial chord device is disclosed in the patent [201080011563.0], the device includes a flexible rope, the flexible rope has a first end and a second end; [0003] A first attachment element at the first end of the cord configured to attach the cord [0004] attached to a first location at a first tissue; [0005] a second attachment element at the second end of the cord configured to attach the cord [0006] to a second location at the first organization; [0007] wherein said first and second attachment elements each comprise a piercing member and a securing member, and said cord is in said [0008] At least a portion between the first end and the second end is configured to be secured to a second tissue. [0009] This device has the following disadvantages: [0010] 1. Req...

AI Technical Summary

Problems solved by technology

[0010] 1. Routine extracorporeal circulation is required, and the patient's heart stops beating

[0011] 2. The metal hook is used to fix the valve, which will cause great damage to the valve. As a metal foreign body, it is not clear whether the patient can undergo MRI examination after surgery.

[0012] 3. The artificial chordae fix the valve and papillary muscle under cardiac arrest, and cannot represent the actual distance between the two after the heart is filled

[0013] 4. It is impossible to perform real-time surgical operations with the help of existing imaging methods, which may prolong the operation time. The operation time is long, and extracorporeal circulation machines are required, which increases the cost of medical treatment
