Embodiment 1

[0043] The preferred embodiment discloses a valve ring repair device. Such as Figure 1 to Figure 9 As shown, the annulus repair device includes an outer sheath 1 with a controllable bending angle, a puncture catheter 2 arranged at the front end of the outer sheath 1 , a rivet 3 arranged in the puncture catheter 2 , a connecting wire 4 connected to the rivet 3 , And the operating handle 5; when the rivet 3 is fixed on the annulus 7 to be repaired, pulling the connecting wire 4 can adjust the distance between the rivets 3, and then drive the annulus 7 to be repaired to shrink. Wherein, the diameter of the connecting wire 4 is preferably 0.05-1 mm, and the material for making it is preferably but not limited to NiTi, PTFE, PA, PET or PEEK.

[0044] The method for using the annulus repair device comprises the following steps:

[0045] Step S1, the annulus repair device enters through the punctured blood vessel and reaches above the annulus 7 (the mitral valve) to be repaired. ...

Embodiment 2

[0062] This preferred embodiment discloses a valve ring repair device, the structure of which is basically the same as that of the preferred embodiment 1. The difference is that if Figure 10 to Figure 13 As shown, the rivet 3 is laser cut from a hard tube, or braided from metal wire, or composited from a hard tube laser cut and wire braided. The rivet 3 includes a rivet body 33 , and barbs 34 are formed on the outer surface of the rivet body 33 . Wherein, the combination of hard tube laser cutting and metal wire braiding means that a layer structure cut by hard tube material laser cutting is arranged on the inside or outside of another layer structure made of metal wire braiding.

[0063] The rivet 3 is prepared by laser cutting of a hard tube (such as a nickel-titanium alloy tube) and then expanded by a thermal power source, which has low cost and high processing efficiency; the rivet 3 is prepared by braiding a metal wire (such as a nickel-titanium alloy), and the product ...

Abstract

The invention discloses a cingulum reparation device and an application method thereof and belongs to the technical field of mitral valve regurgitation treatment devices and application methods thereof. The device solves the problems of large treatment wound, high complication occurrence rate and the like in the prior art. The device comprises an outer sheath tube with a controllable bending angle, a puncture catheter which is arranged at the front end of the outer sheath tube, rivets which are arranged in the puncture catheter, connection threads which are connected to the rivets and an operating handle; when the rivets are fixed to a cingulum to be repaired, the connection threads can be pulled to adjust the distances between the rivets, and then the cingulum to be repaired is driven to shrink. According to the cingulum reparation device and the application method thereof, mitral valve regurgitation is subjected to cingulum reparative therapy by the catheter through minimally invasive intervention, the wound is small, the surgical complication occurrence rate is low, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of a mitral valve regurgitation treatment device and its use method, in particular to a valve ring repair device and its use method. Background technique [0002] The mitral valve structure of the heart is composed of annulus, leaflets, chordae and papillary muscles. To achieve the functional integrity of the mitral valve, the size of the annulus is appropriate, the structure of the leaflets is complete, and the contraction of the papillary muscles pulls the chordae to develop the leaflets. The support function of the left ventricle, the closing force generated by the muscle contraction of the left ventricle are appropriate, and the shape and function of the ventricle are normal. Abnormalities in any of the above factors will lead to mitral regurgitation (mitral regurgitation, MR). [0003] The current method of treating mitral valve regurgitation disease is mainly traditional surgical treatment, the defect...
