Medical securing device for securing an implant device with a securing member

Abstract

A medical securing device (100) for securing a implant device (40, 101), such as a cardiac implant device (40, 101) with a securing member (102) into a tissue, such an annulus (20) of a heart valve (18) comprises a first elongated stem (103) having proximal (103A) and distal (103B) ends. The distal end (103B) of the first stem (103) has a receiving member (104) for receiving the securing member (102). During a mutual movement (105) of the distal end (103B) of the first stem and the receiving member (104), the distal end (103B) of the first stem is configured to introduce with the receiving member (104) the securing member (102) to the implant device (101) to secure the implant device (101) to the tissue (20) with the securing member (102).

Description

Technical field [0001] The invention relates to a medical fixing device, which is used to fix an implant device with a fixing member, especially a heart implant (annuloplasty medical) device. Specifically, the present invention relates to a medical fixation device used for open heart surgery and for fixing a heart implant device in the valve annulus of a heart valve, such as a mitral valve or three The cusp is composed of valve tissue and includes an annulus and multiple leaflets. Background technique [0002] Figure 1A A portion of the heart 12, the mitral valve 18 and the left ventricle 14 are shown. The mitral valve is surrounded by a ring 20 at its border. The valve has two cusps or leaflets 22,24. Each of these cusps or leaflets 22, 24 is connected to the corresponding papillary muscle 27, 29 via their respective connecting chordae 26, 28. In a normal healthy individual, the free edges of the opposing leaflets will close the valve by engagement. However, for some indivi...

AI Technical Summary

Problems solved by technology

However, the screws are very small, making their assembly, positioning and control very difficult

These screws have to be inserted through the first (upper) annular support part 42 and the second (lower) annular support part 44 (small holes in both parts), which is very demanding because if the first screw is tightened too tightly , which distorts the sections slightly so that the other holes can't be aligned and other screws can't be inserted

In addition, there is a great risk of small screws falling into the structure of the heart, since for example no safety blankets can be used

Also, magnetic materials cannot be used due to the possibility of subsequent magnetic imaging
