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.

Claims

1. An endocardial heart function intervention device comprising, at least one ring shaped device from a set of three ring shaped devices having substantially elliptical, circular and asymmetrical body shapes, respectively, said at least one device having transversal dimensional variations comprising resilient portions and formed connection portions at spaced apart locations along the device at so that the device is configured to be engagable with and connectable within a heart and onto an endocardium wall, each shaped device being formed as an elastic structure having flexibility along an axis of a ventricular cavity and having radial elasticity during the diastolic phase which diminishes inversely with endoventricular pressure so that each device, when connected in place, can be adjusted to a section of the endocardial wall at a neutral rest position and can thereafter expand to receive energy from the endocardial wall during a first part of a diastolic phase, and to cede energy received to the endocardial wall during a first part of a systolic phase, wherein the intervention device comprises a set of three ring shaped devices, each of said rings in the set having one of an elliptical, circular or asymmetrical shape and the three ring shaped devices are interconnected together within the heart.

2. An endocardial heart function intervention device comprising, at least one ring shaped device from a set of three ring shaped devices having substantially elliptical, circular and asymmetrical body shapes, respectively, said at least one device having transversal dimensional variations comprising spring portions and formed connection portions at spaced apart locations along the device at so that the device is configured to be engagable with and connectable within a heart and onto an endocardium wall, wherein the formed connection portions are dimensionally different from the spring portions within the body shapes, each ring shaped device being formed as an elastic structure having flexibility along an axis of a ventricular cavity and having radial elasticity during the diastolic phase which diminishes inversely with endoventricular pressure so that each device, when connected in place, can be adjusted to a section of the endocardial wall at a neutral rest position and can thereafter expand to receive energy from the endocardial wall during a first part of a diastolic phase, and to cede energy received to the endocardial wall during a first part of a systolic phase, wherein the intervention device comprises a set of three ring shaped devices, each of said rings in the set having one of an elliptical, circular or asymmetrical shape and the three ring shaped devices are interconnected together within the heart.

3. An endocardial heart function intervention device comprising, at least one ring shaped device from a set of three ring shaped devices having substantially elliptical, circular and asymmetrical body shapes, respectively, said at least one device having transversal dimensional variations comprising spring portions and formed connection portions at spaced apart locations along the device at so that the device is configured to be engagable with and connectable within a heart and onto an endocardium surface, with the formed connection portions having a different shape from the remainder of the at least one ring shaped device, each ring shaped device being formed as an elastic structure having flexibility along an axis of a ventricular cavity and having radial elasticity during the diastolic phase which diminishes inversely with endoventricular pressure so that each device, when connected in place, can be adjusted to a section of the endocardial wall at a neutral rest position and can thereafter expand to receive energy from the endocardial wall during a first part of a diastolic phase, and to cede energy received to the endocarcdial wall during a first part of a systolic phase, wherein the intervention device comprises a set of three ring shaped devices, each of said rings in the set having one of an elliptical, circular or asymmetrical shape and the three ring shaped devices are interconnected together within the heart.
