Title:
IMPLANT RELEASE DIRECTAIONAL MARKING DEVICE, IMPLANT CONVEYING SYSTEM AND WORKING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/231446
Kind Code:
A1
Abstract:
An implant release directional marking device, an implant conveying system and a working method therefor. The implant release directional marking device comprises a marking structure having a marking plate (20), the marking plate (20) being movably arranged on the side wall of an outer pipe (10) and, when not in use, being embedded in the side wall of the outer pipe (10) . During use, the proximal end of the marking plate (20) is tilted in the direction away from the axis of the outer pipe(10), such that controlled directional marking is performed after the implant conveying system enters a human body, and the circumferential angle of a valve stent can thus be controlled so that a special-shaped valve stent can be well matched with the native valve annulus, and the precision of releasing a valve prosthesis by the implant conveying system is improved.
