Embodiment Construction

[0045] refer to figure 1 , figure 1It is a schematic diagram of the structure of the valve prosthesis after it is released. The valve prosthesis 100 can be pressed and held in the catheter of the delivery system and implanted into the body through the catheter. Although the valve prosthesis 100 shown in the illustration is a valve prosthesis 100 with a relatively common shape, the shape of the valve prosthesis 100 of the present invention is not limited to any specific shape. The valvular prosthesis 100 includes a mesh-shaped stent 110 and leaflets 120 coated on the outer surface of the stent 110 , the stent 110 includes an inflow channel 111 and an outflow channel 112 connected in sequence, and from the outflow channel 112 One end of the hanging ear 113 extends away from the inflow channel 111 . The present invention has no special limitation on the material for making the stent 110 , and may be any material in the art, for example, a shape memory alloy. There is no partic...

Abstract

The invention provides a loading device for compressing an implant. The loading device comprises a guide cover which is provided with an inner cavity, a far-end opening and a near-end opening, a baseand a height adjusting piece set, wherein the inner cavity communicates with the far-end opening and the near-end opening, and the far-end opening is smaller than the near-end opening; the base is used for pushing an implant to move from the near-end opening of the guide cover to the far-end opening of the guide cover in the inner cavity of the guide cover; and the height adjusting piece set is detachably connected with the base, and is used for adjusting the axial distance between the near end of the implant and the base. The loading device disclosed by the invention has the characteristic ofhigh universality.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a loading device. Background technique [0002] The heart valve is the gate of the heart's blood circulation. Once stenosis or insufficiency occurs, the heart will suffer from insufficient power or failure, and heart valve diseases such as chest tightness, asthma, general edema, weakness, and chest pain will occur. There is a general law in the development of human disease treatment technology, which usually goes through a process from impracticable to promising, from major trauma to minor trauma, or even no trauma. Similarly, valvular heart disease has also experienced the earliest untreatable, later traditional sternotomy incision surgery and recent minimally invasive (small incision) surgery, and is currently in the era of transcatheter valve interventional therapy. If traditional median sternotomy surgery is called the 1.0 era of heart valve disease treatment, an...
