A valve prosthesis which is especially useful in the case of aortic stenosis and capable of resisting the powerful recoil force and to stand the forceful balloon inflation performed to deploy the valve and to embed it in the aortic annulus, comprises a collapsible valvular structure and an expandable frame on which said valvular structure is mounted. The valvular structure is composed of physiologically compatible valvular tissue that is sufficiently supple and resistant to allow the valvular structure to be deformed from a closed state to an opened state. The valvular tissue forms a continuous surface and is provided with strut members that create stiffened zones which induce the valvular structure to follow a patterned movement in its expansion to its opened state and in its turning back to its closed state.

A device and method for treatment of atrioventricular regurgitation comprises a suturing device. The suturing device is configured to be introducible, via blood vessels leading to the heart, to two leaflets of the atrioventricular valve between the atrium and a corresponding ventricle of the heart. The suturing device is configured for binding together the two leaflets along the free edges of the leaflets. A method of using the device includes inserting the suturing device into a catheter, introducing the catheter to the heart and positioning a distal end of the catheter close to two leaflets of an atrioventricular valve, capturing the free edges of the two leaflets with the suturing device in its open state, binding together the two leaflets by transition of the suturing device into its closed state, and retracting the catheter from the heart. As a result, the closing of the valve is improved.

A glasses type display that is connected to an information communication terminal via a wire line or a wireless line, in which the operation by the user is made simple by preventing error operation and the power consumption is decreased by not consuming the unnecessary power, is provided. The glasses type display provides lenses, a main frame, side frames, a microphone, a speaker(s), open and closed state detecting sensors, wearing state detecting sensors. When the user opened the side frames, the open and closed state detecting sensors react, and the wearing state detecting sensors become the on state. When the user put on the glasses type display, the lenses automatically become the on state by that the wearing state detecting sensors detected the wearing state. And when the reaction from a part of the wearing state detecting sensors was turned off, caused by some vibration, the lenses are not immediately turned off. Therefore, an error operation is avoided. When the side frames were closed, the lenses were turned off automatically by the operation of the open and closed state detecting sensors. Therefore, the unnecessary power consumption is avoided.
