COROLLA

Medical apparatus, namely, a device comprising an elastic metallic implant to be inserted into the left ventricle (LV) and positioned on the endocard, the implant harnessing energy produced by the LV during systole and releasing it during diastole, for improving ventricular diastolic function, intended for implantation in a minimally invasive procedure thorough a trans-apical procedure or catheterization and kits consisting of the elastic metallic implant, and medical instruments in the nature of Trans Apical Sheath (TAS), Dilator or catheter, Delivery Tool (DT) for placement of implant and Papillary Muscle (PM) marker for marking the papillary muscles location on the external surface of the left ventricle, all sold as a unit; kits comprising a circumferential elastic metallic implant for long term implantation, Dilator for dilating the incision through the apex for the TAS insertion, TAS for a transapical implantation procedure for the device implantation by the DT, and PM marker for marking the papillary muscles location on the external surface of the LV; kits comprising a circumferential elastic metallic implant for long term implantation, and additional medical instruments, such as catheters, to enable implantation of the implant in a catheterization procedure
