Embodiment Construction

[0046] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention are described in detail with reference to the accompanying drawings.

[0047] Figure 1A A side view of the implant without the membrane attached is shown. For better visibility and better explanation, only line segments lying in front of the paper plane are shown. Some of the following reference numbers are only Figure 1A shown in . Figure 1B The same view is shown with all line segments. Figure 1C The entire device is shown with a membrane attached to the attachment element. The following description applies to all Figure 1A , Figure 1B and Figure 1C .

[0048] The lower part of the implant forms an attachment element 1, a membrane 2 (only in Figure 1C shown in ) can be attached to the attachment element 1 . The membrane 2 and the attachment element 1 form a closure element that can be positioned in the annular region of a heart valve, such as the mitral valv...

Abstract

The invention relates to a heart implant comprising a tubular attachment element (1) for attaching an inflatable membrane (2), particularly an inflatable membrane (2) being coaxially positioned aroundthe tubular attachment element (1) and fixed to it, the tubular attachment element (1) at one of its ends being split into several strips (4), the strips (4) extending away from the tubular attachment element (1) and forming an expandable cage (C), particularly for fixing the heart implant to the atrium of the heart by surface contact between an exterior surface of the expandable cage (C) and aninterior atrium surface, each one of the strips (4) being split into two branches (4a, 4b, 4a', 4b',...), each respective branch (4a) being merged into a new strip (5) together with another respectivebranch (4b') of a neighboring strip (4) wherein such splitting and merging is performed one after the other at least three times and the number of strips (7) being formed of the last merged branches(6a, 6b) at the end of extension corresponding to the number of strips (4) at the one end of the tubular attachment element (1).

Description

technical field [0001] The present invention relates to a cardiac implant, and more particularly to a cardiac implant configured to reduce or eliminate cardiac valve insufficiency after implantation in the heart. Background technique [0002] Typically, the implant is positioned in such a way that a closure element of the implant is located in the valve annulus and closes a gap of closed leaflets. For this purpose, the closure element is connected to an anchoring element configured to fix the closure element at a desired position within the heart, namely in the valve annulus, preferably with the plurality of closure elements. leaflets touch. [0003] In the known art, it is known to fix the closure element using an anchoring element that penetrates the myocardium. In addition to this invasive approach, modern implants provide a less invasive fixation only by contacting the inner wall of the atrium with the outer surface areas of an expanded retainer connected to the closur...
