  • Balloon dilatation catheter provided with soft coating
    Patent number: 9199068
    Abstract: The present invention relates to technical field of cardiac medical instruments, and more particularly to a balloon dilatation catheter provided with soft coating tip. In the balloon dilatation catheter provided with soft coating tip of the present invention, the balloon dilatation catheter comprises a balloon, and inner catheter. A distal end of the balloon at a terminal end of the inner catheter extends outward to form a catheter tip with taper inner cavity. A tip coating layer made of a material which is softer than a material of the balloon is coated on the catheter tip. The material of the balloon generally selects a relatively hard material. The distal end of the balloon extends outward to form a catheter tip.

  • Battery controller for controlling batteries of different kinds and including battery monitoring means for calculating remaining operation time and an information processing apparatus including such battery controller
    Patent number: 5963010
    Abstract: A battery controller for controlling at least two batteries of different kinds, includes a kind-of-battery detection unit for detecting a kind of battery, and a battery switching unit in which a switching voltage, a suspended mode shift voltage and a termination voltage having different values in accordance with the kind of the battery detected by the kind-of-battery detector are previously set to compare an output voltage of a battery being discharged with the previously set switching voltage, suspended mode shift voltage and termination voltage so that switching of the battery being discharged, stopping of operation of an apparatus being supplied with electric power by the battery being discharged or stopping of supply of electric power by the battery being discharged is performed.
