Device that can be implanted in a minimally invasive manner and mitral valve implant system

A device for implanting with minimally-invasive surgery in the beating heart of a patient for adjusting the shape and size in an anatomical opening or another lumen, which comprises an annuloplasty ring, wherein said annuloplasty ring

• has at least one tissue anchor;
• has a guiding configuration, when the annuloplasty ring is compressed to a size that can be inserted into the left atrium, and can be deformed into an open configuration, in which the annuloplasty ring expands to its original starting shape to influence an anatomical opening and can be fastened there;
• has a circular shape, which has an inner layer for stabilization and at least one outer surrounding layer, through which at least one tissue anchor thread is drawn;
• and
• has a rounded ring element, said rounded ring element having
• an anterior section, which is equipped with tissue anchor positions for an anterior side of a mitral valve annulus of the anterior cusp, and
• a posterior section, which is equipped with tissue anchor positions for a posterior side of the mitral valve annulus of the posterior cusp, which provides a tissue anchor position of the annuloplasty ring with at least one tissue anchor thread of at least one tissue anchor;
• wherein at least one tissue anchor can be arranged and implanted around the mitral valve annulus and wherein
• each at least one tissue anchor is formed with a respective coil screw and a respective tissue anchor thread in order to position the annuloplasty ring on at least one tissue anchor;
• the tissue anchor thread of each at least one tissue anchor is fastened with a fastener to the annuloplasty ring, and
• the fastener has a clamp which can be put onto the tissue anchor thread and is configured to permanently clamp the tissue anchor thread in an opening of the annuloplasty ring.
