Problems solved by technology

The first disadvantage of this repair procedure is that it is only possible when the heart is inactive, so surgical repair requires the heart to be stopped and the blood drained while using extracorporeal circulation
The second disadvantage is that the success of the operation depends heavily on the skill of the surgeon
This configuration has been found to cause problems during echocardiographic positioning and instrument placement
In addition, the control mechanism is quite complex

Embodiment Construction

[0104] The following more detailed description of an instrument embodiment is representative of exemplary embodiments of the present technology, wherein like parts are designated by the same reference numerals throughout. Standard medical reference planes and descriptive terminology are used throughout this specification. In particular, proximal means towards the torso, or towards the user in the case of an inanimate object, and distal means away from the torso, or away from the user in the case of an inanimate object.

[0105] Figure 1 to Figure 3 An exemplary embodiment of a gripping structure as part of an instrument for repairing an atrioventricular heart valve is shown. figure 1 The gripping structure 3 comprising the body 4 and the jaws 5 is shown in an open position. The gripping structure may be formed as a bullet gripper (bullet gripper). The gripping structure may be 0.75 cm to 1.2 cm in length. The jaws may be formed as distal nose cone tips that can be advance...

Abstract

The invention relates to the field of minimally invasive surgical and interventional cardiology devices for heart valve repair. It particularly relates to an instrument for repairing an atrioventricular heart valve, mitral heart valve or also the tricuspid heart valve in a minimally invasive manner, and to an according method. In particular, the instrument comprises a first tube having a tube axis defining an axial direction; a leaflet grabbing structure arranged at a distal part of the first tube and contiguous to the first tube, the leaflet grabbing structure comprising a main body and a jaw, the jaw being movable relative to the main body; wherein the jaw comprises a first proximally facing abutment surface and the main body comprises a second distally facing abutment surface; the instrument further comprising a needle, wherein the needle is cannulated and forms an inner tube, and wherein the needle is releasable from the first tube and movable relative to the main body in axial directions, whereby the leaflet grabbing structure is capable of clamping a leaflet of the heart valve between the first and second abutment surfaces; and wherein the jaw being formed to allow the needle to extend therethrough while the leaflet is being clamped.

Description

technical field [0001] The present invention relates to the field of minimally invasive surgical and interventional cardiology devices for heart valve repair. In particular, it relates to devices for the minimally invasive repair of atrioventricular, mitral or tricuspid heart valves, and corresponding methods. Background technique [0002] Prolapse of the mitral valve leaflets into the left atrium and resulting valve insufficiency can lead to severe cardiac dysfunction. One of the causes of this prolapse is a damaged tendon (chordae) that connects the mitral valve leaflets to the papillary muscle through the left ventricle. Such damage may be the result of, for example, myocardial infarction, tissue degeneration, or infectious disease. [0003] Repair of this prolapse requires one or more leaflets, for example, by synthetic fibers (eg fibers) reconnect to the papillary muscles. This method according to the prior art requires suturing the implant to the papillary muscle....
