Embodiment Construction

[0054] exist figure 1 The human chest 1 schematically shown in FIG. 1 shows a minimally invasive access 2 to the heart 3 for minimally invasive mitral valve surgery. Interventions on the mitral valve 14 of the heart 3 (see Figure 5 ) can be minimally invasive, ie without the use of a heart-lung machine. For example, mitral valve repair can be performed using a hybrid OR protocol in anesthetized patients. Then, in the case of right lung collapse, several small lateral openings are made in the right chest in the 3' or 4' intercostal space. This intervention is performed using a minimally invasive technique (also known as keyhole surgery) and uses instruments such as trocars, wound dilators, optics, atrial roof retractors, and others.

[0055] As before, access 2 to the heart 3 is through a small chest opening 4 located on the right side 5 of the third or fourth intercostal space 6 . During the procedure, the chest opening 4 is kept open with a wound dilator 7 . Other exami...

Abstract

The invention relates generally to the field of heart surgery. In the field of surgery, instruments are used to examine the interior of living organisms and / or for the purpose of surgical intervention. These also include implants for producing the functional capability of a heart. The invention relates to such an implantable device and to a method for eliminating regurgitation in the region of theheart. The implantable device is an annuloplasty ring having a plurality of tissue anchors. An unfolded annuloplasty ring is positioned in the cavity of a body element in order to constrict a body opening. Previously, every tissue anchor of the annuloplasty ring is introduced into a precise position on the edge of the mitral valve annulus intravascularly, by means of the minimally invasive technique. The arcuate or annular configured annuloplasty ring is placed onto the thus anchored fasteners and fastened in order to influence the septal and lateral annulus of the mitral valve in size and shape and to close the gap between the anterior and posterior leaflets in the valve.

Description

technical field [0001] The invention relates to a minimally invasive implantable device and a mitral valve implant system. Background technique [0002] This medical technology is used to detect and eliminate disease to restore the patient's health. The present invention relates to the field of cardiac surgery. In the field of cardiac surgery, instruments, devices or methods are used to examine the interior of the heart and / or to use it for surgical interventions. In particular, the present invention relates to minimally invasive reconstruction of heart valves, using surgical instruments that allow access to the heart via access to perform various reconstructions and using the device of the present invention on a beating heart. The device involves an implantable device that is fixed to tissue, thereby restricting or compressing the dilated opening. The present invention relates to an annuloplasty ring that can be used in cavities of body organs, especially in the heart, t...
