A device for placing an anchor in annular tissue
Embodiments of the present application relate to the field of implantable prostheses, and particularly to a device suitable for setting an anchor on a valve annulus tissue. The device comprises a locking wire assembly, a winding member, an anti-loosening member and a limiting member. The locking wire assembly is used to pull the anchor, and the locking wire assembly can be partially wound on the winding member when the winding member rotates. The anti-loosening member is used to prevent the locking wire assembly wound on the winding member from being separated from the winding member. The limiting member is used to drive the winding member to rotate and limit the movement of the anti-loosening member. The device provided by the embodiments of the present application changes the length of the locking wire assembly by winding the locking wire assembly on the winding member, thereby pulling the anchor set on the valve annulus tissue to repair the valve annulus tissue. At the same time, by preventing the locking wire assembly wound on the winding member from being separated from the winding member and limiting the movement of the anti-loosening member, it is ensured that the locking wire assembly wound on the winding member will not be separated from the winding member, thereby ensuring that the locking wire assembly can pull the anchor and ensuring the repair effect.

Devices for repairing annulus tissue and systems for repairing annulus tissue
This application relates to the field of implantable prostheses, specifically to a device and system for repairing valve annulus tissue. The device for repairing valve annulus tissue includes a prosthesis, an anchor, a locking wire, and an anchor driver. The anchor, guided by the prosthesis, is driven by the anchor driver and screwed into the valve annulus tissue. The locking wire is disposed on the prosthesis. The prosthesis, locking wire, and anchor driver are configured to increase the contact area between the anchor and the valve annulus tissue. The repair device provided by the embodiments of this application makes it less likely for the anchor screwed into the valve annulus tissue to detach, increasing the reliability of the fixed connection between the anchor and the valve annulus tissue, thereby helping to ensure the effectiveness of the valve annulus tissue repair. Simultaneously, by increasing the contact area between the anchor and the valve annulus tissue, the number of anchors screwed into the valve annulus tissue can be reduced, shortening the repair time and improving repair efficiency.

PRÓTESES IMPLANTÁVEIS PARA REGENERAÇÃO DE TECIDO E MARCAÇÃO DE SÍTIOS CIRÚRGICOS
Implantable prostheses and related methods are generally described. In some embodiments, the prosthesis may be a generally ellipsoidal (e.g., spherical) shape, formed of one or more subunits. The subunits may be conical or frustoconical, formed through manipulation of a two-dimensional substrate material. The sidewalls of the subunits may be fixed to one another to enhance the stiffness of the prosthesis. In some embodiments, markers may be used to help distinguish the prosthesis in the implant site through medical imaging modalities (e.g., x-ray imaging). In this way, the implant site, which may also be the site of a recent biopsy and / or a diseased tissue resection, may readily be identified. The prosthesis may be formed of a porous material to induce tissue infiltration, which may facilitate natural tissue regeneration for more natural look and feel of the tissue. Tissue infiltration may result in the prosthesis having an enhanced resistance to migration following implantation.
