Abstract
The present invention provides a ventricular function assisting device configured to be implanted in a heart ventricle designed in a form of flower-like configuration comprising two or more petals attached at a base section, said petals comprise elastic elements and/or portions capable of being elastically bent in radial directions and optionally also in sideway and/or longitudinal directions, which allow changing the state of the device between: i) a folded conformation, in which its petals are radially pressed inwardly towards each other to assume a reduced diameter of its flower-like configuration; and ii) a deployed conformation, in which the petals are opened in a radial outward direction as the device is discharged from the delivery tube or sheath into a heart ventricle and implanted thereinside in a preloaded state.
