Suitable materials for reinforcing parts of a sealing lip 52, 54 are metals, ceramics, rubber and or a combination thereof. Preferably, the shell 2 has openings which are formed by the wires of a wire mesh, the struts of a latticework or the holes in a shell shell. It contains as a lubricant a serous fluid, which is also called liquor pericardii. In a compressed state, the device can be introduced into a delivery system. The pericardium 6 can be sealed thereby. The positioning of the at least one augmentation unit 71 in the shell 2 will be explained in more detail in a later section of the description. The sheath is open at the bottom and therefore allows the fluid to exchange between the space inside the sheath and the space between the sheath and the pericardium.

Ein beliebiges geometrisches Objekt kann in verschiedenen Koordinatensystemen beschrieben werden, zum Beispiel in einem kartesischen und einem Polarkoordinatensystem. Durch eine zentrische Streckung mit dem Streckungszentrum Z und dem Streckungsfaktor Ähnlichkeitsfaktor k wird eine Figur F in eine ähnliche überführt Bild 1. Each of the sealing lips 52, 54 may consist of one or more materials. The augmentation units 71 A1 and A2 may serve to support left ventricular failure. In this embodiment, the positioning unit 72 P occupies an area of 114.

Preferably, the at least one sensor is mounted on a shell, which can be introduced into the shell 2. Device according to one of the preceding embodiments 25, wherein 3 mm to 2 cm of the shell extends through the opening. The soft conical tip 102 may have a round, oval or polygonal lumen in the middle. As the heart muscle declines or expands, a positioning unit 72 may be further expanded or relaxed to ensure an optimal fit. The expandable unit 71, 72 may be configured to exert pressure on the heart 61.

As a fold, an outwardly directed buckling edge 711 can be defined. As an example, three augmentation units 71 and three positioning units 72 are shown. A membrane 21 on a grid or braid can ensure that expansion of an expandable unit located on the grid or braid is only in a direction inwardly of the braid or grid. This pressure may be a permanent pressure or it may be a periodic pressure. If the at least one expandable unit is a mechanical unit that can transition from an unexpanded state to an expanded state or from an expanded state to a non-expanded state by means of electrical energy, the cable 4 includes lines that suitable to transfer the necessary energy from the supply unit 30 to the expandable unit.

Zentrische Streckung

Auch hier gehören die zentrischen Streckungen aber stets zu den Dilatationen und den Affinitäten und für Fixpunkte und Fixgeraden gilt das Gleiche wie im reellen Fall. The self-expanding shell 2 and the sheath 7 in this illustration have a recess 22 so as not to compromise the inferior vena cava in the implanted state of the device. Areas that require increased flexibility may be areas that must be compressed more than other areas when introduced into a delivery system. The length of the extension struts 23 can be between 1cm and 10cm, especially between 4cm and 7cm. Expansion of the at least one expandable unit 71, 72 can reduce the volume of the ventricle and thus result in expulsion of blood from the chamber.

The plug part 90 will be explained in more detail in a later section of the description. The dotted-dashed line 615 represents a cut line at which the 3D shape 611 can be cut open and then unrolled. These may, for example, be areas which serve as abutments for expandable units 71, 72. If more flexibility in the shell 2 is desired, the slit of the tube can be modified such that one, two or three cell rows are omitted at the location of the recess 22. A seal over the plug system may be a sealing tape or a gasket.
