Abstract
The invention consists in a device that concerns the optimization of the cardiac geometry in patients with heart failure. The device comprises one or more elastic elements in the radial direction towards the inside of the ventricle and plastic deformation in a direction that is transversal to the said ventricle, the element being equipped with means for attaching it to the internal wall of the ventricle.
Claims24
Endoventricular device for treating dilating cardiomyopathy by correcting the geometry of the left ventricular cavity (1) without the removal of cardiac mass, characterised by the fact that the device (6, 7 and 8) consists of at least one element whose shape is substantially similar to that of the perimeter of the portion of endocardium to which it is applicable, and which is respectively susceptible to elastic deformation in a radial direction towards the inside of the ventricle and plastic deformation in a direction that is transversal to the said ventricle, the element being equipped with means (12) for attaching it to the internal wall of the ventricle and/or the mitral valve annulus.
Device according to the previous claims characterised by the fact that the said element consists of closed or open rings.
Device according to the previous claims characterised by the fact that the transversal section of the said element is rectangular, or circular. or elliptical, or semi-circular, or semi-elliptical.
Device according to the previous claims characterised by the fact that the said element is constituted of closed or open bands.
Device according to the claims from 1 to 7 characterised by the fact that it is constituted of linear strips.
Device according to the claims from 1 to 5 characterised by the fact that it is constituted of closed or open helicoid springs.
Device according to the claims from 1 to 5 characterised by the fact that it is constituted of closed or open planar springs.
Device according to the claims from 2 to 5 characterised by the fact that the suturing stitches are reinforced with pladgets of biological or biocompatible material.
