Integrally detachable valve clamp and conveying system thereof

Abstract

The invention relates to the field of medical instruments, in particular to an integrally detachable valve clamp and a conveying system thereof, the integrally detachable valve clamp comprises a control handle, a conveying catheter connected with the control handle and a valve clamp connected with the conveying catheter, the valve clamp is provided with an inner pipe and an outer connecting pipe, and the inner pipe and the outer connecting pipe are both provided with detachable connecting mechanisms; the conveying catheter comprises a first conveying pipe, a center control piece and a second conveying pipe, and detachable connecting mechanisms matched with the detachable connecting mechanisms are arranged at the far end of the first conveying pipe and the far end of the second conveying pipe correspondingly. The detachable connecting mechanism on the inner pipe is connected with the detachable connecting mechanism on the first conveying pipe through the middle control piece to form a first detaching part, the detachable connecting mechanism on the outer connecting pipe is connected with the detachable connecting mechanism on the second conveying pipe through the middle control piece to form a second detaching part, and when the middle control piece is moved away from the first detaching part and the second detaching part, the detachable connecting mechanism on the outer connecting pipe is detached. The first conveying pipe is separated from the inner pipe, and the second conveying pipe is separated from the outer connecting pipe.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an integrally detachable valve clip and a delivery system thereof. Background technique [0002] The anatomical structure of the mitral valve is complex, including leaflets, valve ring, chordae and papillary muscles, which play an important role in maintaining the function of the left and right ventricle respectively. Any disease that affects the structural integrity and normal function of the valve leaflets, valve ring, chordae, papillary muscle, and left ventricle may lead to severe mitral regurgitation (MR), which can cause left ventricular failure, pulmonary hypertension, and , atrial fibrillation, stroke and death. According to the latest epidemiological survey data of western developed countries such as the United States, mitral valve regurgitation is the most common type of valvular disease in the elderly population over 65 years old. At present, although there is no autho...

AI Technical Summary

Problems solved by technology

When the leaflet is captured between the anchor member and the septum member, the septum member is configured to provide a flow path through the prosthetic device between the first lumen and the second lumen such that blood can pass through the septum member from the The second cavity flows back into the first cavity; after the valve clip is implanted in the target position in this patent, the delivery system needs to rotate the inner tube first, so that the inner tube is disengaged from the thread on the valve clip, and then the inner tube is pushed toward the valve clip. The proximal end is evacuated, and then the detachable component is moved proximally to separate it from the valve clip; the operation steps are relatively cumbersome, and at the same time, the structural design of the detachable component is complex, requiring high assembly technology and difficult to implement

[0006] To sum up, the design of the detachable connection structure between the delivery system and the valve clip in the prior art is relatively complicated, which requires high assembly technology, and the complex structure further makes its operation process cumbersome.
