Device and method to control volume of a ventricle

ActiveUS7530998B1Small sizePrevent further enlargement of a diseased heartHeart valvesHeart stimulatorsCardiac cycleReverse remodeling
A device used to treat heart disease by decreasing the size of a diseased heart, or to prevent further enlargement of a diseased heart. The device works by limiting the volume of blood entering the heart during each cardiac cycle. The device partitions blood within the heart, and protects the heart from excessive volume and pressure of blood. The device is placed within the interior of the heart, particularly within a ventricular cavity. The device is a hollow sac, with two openings, which simulates the shape and size of the interior lining of a ventricle of a normal heart. It allows the ventricle to fill through one opening juxtaposed to the annulus of the inflow valve to a predetermined, normal volume, and limits filling of the heart beyond that volume. It then allows blood to be easily ejected through the second opening through the outflow valve. By limiting the amount of blood entering the ventricle, the ventricle is not subjected to the harmful effect of excessive volume and pressure of blood during diastole, the period of the cardiac cycle when the heart is at rest. This allows the heart to decrease in size, or to reverse remodel, and to recover lost function. In some applications, a second device may be simultaneously placed inside the heart to take up excessive space between the heart and the primary device.

Semiconductor apparatus for fingerprint recognition

A semiconductor apparatus, which comprises: a substrate having a transistor; a first electrode formed on the substrate and connected to the transistor; a second electrode formed on the substrate and electrically separated from the first electrode; and an insulating film formed on the substrate so as to cover the first electrode, wherein, when a plane of the insulating film which is not on a side of the substrate is taken as a first plane, a surface facing the first plane of the first electrode is taken as a first surface, and a surface facing the first plane of the second electrode is taken as a second surface, a distance between a surface of the substrate and the second surface is larger than a distance between the surface of the substrate and the first surface. By virtue of having the above unique structure, the semiconductor apparatus of the present invention is advantageous in that, when a finger or any other material which is electrostatically charged is brought closer to the substrate, the static electricity is not discharged into the electrode but into the static-electricity drawing wiring and then drawn out of the semiconductor device, so that the semiconductor devices, the circuits and the like which are connected to the electrode can be prevented from suffering a damage due to the static electricity and from losing the functions thereof.
