Filed: 2002-05-15
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method and device by which a thin sheet magnet that is high in residual magnetization and is large in an aspect ratio can be manufactured.  <P>SOLUTION: In the method, a film is formed of slurry composed of magnet powder, a binding material, and a solvent and the intensity of an oriented magnetic field is increased in accordance with the cured degree of the slurry film. To be concrete the slurry film is disposed between the pole pieces of an electromagnet on a placing base provided with a heating device and the intensity of the oriented magnetic field is increased while the cured degree of the slurry film is controlled by heating the film at a fixed rate of temperature rise. When a magnetic field is applied to the low-viscosity slurry in which the magnet powder is scattered, the surface of the slurry is not maintained in a flat state, because the magnet powder is arranged in the direction of the magnetic fluxes. However, according to this invention a sheet magnet having high characteristics can be obtained, because this phenomenon does not occur.  <P>COPYRIGHT: (C)2004,JPO

Title: Ventricular assisting device and ventricular assisting method
Inventor: LANDESBERG AMIR
IPC: A61F2/48
Filed: 2002-05-16
Abstract: PROBLEM TO BE SOLVED: To enable the recovery of a failing heart. SOLUTION: In this device for assisting the failing heart by use of a single blood displacement chamber 19 and a single cannula 14, the cannula is inserted to an failing ventricular cavity 15 and connected to the blood displacement actuator 18. This device causes a displacement of blood at a critical time for a critical period in a time change curve of blood such that the systolic function of the heart is improved, or the cardiac output is increased to the normal pressure. This device further improves the diastolic function by increasing the ventricular compliance to improve the rapid relaxation of the ventricular wall. This device provides an additive external work without deteriorating the mechanical function of the failing ventricle, and further reduces the energy consumption of the failing heart to improve the coronary perfusion.  Consequently, this device improves the balance between the energy supply (coronary perfusion) to the ventricular wall and a mechanical request.
