Embodiment Construction

[0053] exist figure 1 The heart 1 shown in schematic and overview form in , is rotated about its longitudinal axis in the left chest, so that the right half of the heart lies more on the anterior chest wall, while the left half of the heart tends to point backwards. Starting from the known prior art, the object of the present invention is to develop a heart valve implant 11 that passes through the right chest and 1 of the left atrium 3 and from there by means of known surgical instruments and trocars 5 into the left ventricle 7 and anchored there.

[0054] Thus, the left ventricle 2 is shown with the left atrium 3 and the access 4 in the left atrium 3 to the mitral valve 6 and the left ventricle 7 . Passage 4 is achieved via trocar 5, outer tube pusher 57 and inner tube pusher 158 as shown. The outer tube pusher 57 is guided by the trocar 5 and the inner tube pusher 1 58 is guided by the outer tube pusher 57 . The inner tube pusher I 58 is replaced during operation by anoth...

Abstract

The present invention relates generally to the field of cardiac surgery. In the field of surgery, instruments are used to examine the interior of living organisms and / or to use them for surgical interventions. These also include implants used to produce heart function. The present invention relates to a heart valve implant, especially a heart valve implant for mitral valve reconstruction. Mitral valve reconstruction will be performed on a beating heart using minimally invasive methods. Access to the heart is between the third or fourth intercostal space in the right chest area. Through this access, the heart valve implant of the present invention is inserted into the left ventricle of the heart. The heart valve implant of the present invention comprises a fixation device for grasping the valve leaflets, an anchor element for fixing the fixation device in the myocardium, and a connecting element connecting the anchor element with the fixation device.

Description

technical field [0001] The invention relates to a heart valve implant, in particular to a heart valve implant for minimally invasive heart surgery. Background technique [0002] In cardiac surgery, the use of instruments, devices, or methods to examine the interior of a living organism, such as the heart, and / or for surgical interventions, such as the minimally invasive repair of heart valves, using surgical instruments that allow Portals perform various repairs and use implants on the beating heart. [0003] Various conventional and minimally invasive surgical approaches are currently used in heart valve interventions. Heart valve intervention is the catheter-based or surgical intervention of a heart valve or heart valve leaflets with the goal of restoring heart valve function. A variety of technical methods and surgical instruments are available for functional generation. Such techniques include repair and replacement of heart valves. To perform repairs on the heart, t...
