Abstract: A method for grinding a surface of a rolling element for a roller bearing, the method including scrolling the surface along a trajectory extending successively over at least one draft band and over at least one finishing band of a grinding wheel, each one of the bands being formed from a binder wherein an abrasive is dispersed, the method providing that the binder of the finishing band be of an epoxy resin base, the binder of the draft band being of an organic resin base of a different chemical nature and comprising an abrasive of which the size of the grains is greater than that of the abrasive of the finishing band.

Abstract: A dynamic device for reducing functional mitral regurgitation is described. The device is disposed externally to the heart and effectively acts as a splint for reducing further dilation of the heart in patients diagnosed with cardiomyopathy, and for reducing tethering of the papillary muscle on the mitral valve. The device does not require cardiopulmonary bypass for its installation since it is attached to the outside of the left ventricle, thereby reducing surgical risk, and is not exposed to the patient's blood once installed, thereby reducing the risk of thromboembolic disease.
