Embodiment Construction

[0024] Such as figure 1 As shown, the transvalvular device of the embodiment of the present invention includes: a transvalvular device main body 1 and a transvalvular device rod 2 . The valve-spanning device main body 1 is a hollow three-dimensional structure, and the valve-spanning device rod 2 is connected with the valve-spanning device main body 1 .

[0025] Further, the three-dimensional structure of the main body 1 of the transvalvular device can be spherical, cylindrical, conical, upper-column-lower-conical, strawberry-shaped or rugby-ball-shaped, etc. figure 2 Some examples of shapes of the transvalvular device main body 1 are shown. At least one end of the transvalvular device main body 1 has a connecting part 11 for the transvalvular device rod 2 to be connected to. The heart end, the other end of the main body 1 of the transvalvular device is the distal end. Correspondingly, one end of the transvalvular device rod 2 connected to the transvalvular device main body ...

Abstract

The technical scheme of the invention discloses a valve crossing device which comprises a valve crossing device main body and a valve crossing device rod. The valve crossing device main body is of a hollow three-dimensional structure; the valve crossing device rod is connected with the valve crossing device main body. According to the valve crossing device provided by the technical scheme of the invention, an excellent auxiliary effect is achieved when a guide wire reversely crosses the valve, the surgical operation time is greatly shortened, a chordae tendineae mesh is difficultly penetrated, the complication occurrence probability is greatly reduced, the surgical safety and treatment effect are greatly improved, and the valve crossing device has a high application value.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a transvalvular device. Background technique [0002] Cardiac interventional procedures include transcatheter implantation, that is, catheters are sent into devices from the femoral artery, femoral vein, carotid artery or jugular vein for treatment, such as atrial septal defect closure for congenital heart disease, aortic valve replacement, left atrial appendage blocking etc. In recent years, some doctors have studied transapical or transcardiac puncture routes, which are mainly used in the closure of congenital atrial and ventricular septal defects and interventional aortic valve replacement. The access of these two operations is relatively simple, there are fewer adjacent tissues, and adverse events such as tendon entanglement will not occur. [0003] However, if the interventional treatment of the mitral or tricuspid valve is to be performed from the apical or arterial app...
