Benefits of technology

[0015]The downwards movement of the mitral valve is in a healthy human up to approximately 2 centimetres. The downwards movement accelerates the blood column away from the left atrium and towards the aortic valve in a continuous movement. By means of MRI technology one is able to virtually mark separate pixels inside the blood column and follow their movement. It is possible to show that the blood column flows more or less continuously from the left atrium to the ascending aorta without ever stopping. The blood column is accelerated by the mitral valve piston moving up and down along the cardiac long axis, opening every time it takes a new scoop of blood in an upward movement to the atrium, and closing just before moving back toward the apex. One may estimate the contribution of the long axis pump action of the heart to 30-50% of the total heart pump function.
[0054]Moreover, a system is provided for permanently enhancing left ventricular pump function of a heart of a patient, the system includes a displacement unit for controlled assisted mitral valve movement synchronized with a cardiac cycle of the heart.

Problems solved by technology

Ultrasound imaging and Magnetic Resonance Imaging (MRI) has revealed that this previously taught mode of function is not completely true.

Embodiment Construction

[0087]Specific embodiments of the invention will now be described with reference to the accompanying drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. The terminology used in the detailed description of the embodiments illustrated in the accompanying drawings is not intended to be limiting of the invention. In the drawings, like numbers refer to like elements.

[0088]The embodiments of the invention provide improved left ventricular pump action by means of external power in order to be able to move the native MV along the long axis of the left ventricle (LV) towards and / or away from the heart apex, in synchrony with the cardiac cycle. The here described permanent implant will not take over or replace the remaining na...

Abstract

A device, a kit and a method are presented for permanently augmenting the pump function of the left heart. The basis for the presented innovation is an augmentation of the physiologically up and down movement of the mitral valve during each heart cycle. By means of catheter technique, minimal surgery, or open heart surgery implants are inserted into the left ventricle, the mitral valve annulus, the left atrium and adjacent tissue in order to augment the natural up and down movement of the mitral valve and thereby increasing the left ventricular diastolic filling and the piston effect of the closed mitral valve when moving towards the apex of said heart in systole and / or away from said apex in diastole.

Description

RELATED APPLICATIONS[0001]This application is a U.S. National Stage Application based on International Patent Application No. PCT / SE2001 / 050338 filed Mar. 25, 2011 entitled A Device And A Method For Augmenting Heart Function, which claims priority to U.S. Provisional Application Ser. No. 61 / 317,631 filed Mar. 25, 2010, and Swedish application Serial No. SE1050283-9 filed Mar. 25, 2010, both entitled Device And A Method For Augmenting Heart Function, all of which are hereby incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to an intra-cardiac blood circulation enhancing apparatus, a system for intra-cardiac blood circulation enhancement and a method for enhancing left ventricular pump function of a patient. The present invention is in particular applicable to enhance the pump function of the left ventricle, including as a permanent measure for treating a heart failure disease where the heart function is deficient.BACKGROUND OF THE INVENTION[00...
