  • Publication number: 20060276820
    Abstract: A medical balloon catheter according to the present invention includes a balloon having a groove and/or a projection helically provided relative to the longitudinal axis of the balloon. By such a structure, even after inflating the balloon once, for example, when the balloon is pushed into or removed through a severely stenosed lesion having a diameter smaller than that of the deflated balloon, the balloon can be easily wound more tightly. Therefore, pushing resistance can be reduced.

  • Publication number: 20050065544
    Abstract: The present invention provides a catheter which makes it possible for a biaxial type balloon catheter having a flexible structure in the joint part between a sleeve on the proximal side of the balloon and a shaft on the distal side thereof, showing no abrupt change in rigidity, reducing the step, and capable of being smoothly advanced through highly constricted and curved blood vessel portions, to be manufactured easily with a high production yield using a small number of manufacturing steps. The balloon catheter is a biaxial type for medical use, wherein only the inflation lumen of the shaft is removed from the area extending from the joint part between the shaft and the balloon sleeve on the proximal side to the distal end of the shaft, and main walls of the inflation lumen on the distal side from the joint part are formed by the proximal side balloon sleeve.

  • Patent number: 5049057
    Abstract: A device for continuously measuring and correcting a tackiness of a sheet of rubber material including a feeding unit for continuously feeding an unvulcanized rubber sheet along a flat support surface and a rotatable roller in contact with the unvulcanized rubber sheet, whereby the roller is rotated by the movement of the unvulcanized rubber sheet, and entrained in the sheet feed direction due to a tackiness of the unvulcanized rubber sheet. A load cell is connected to the roller via a linkage, for measuring a resistance to the rolling of the roller, i.e., a change of a position of the roller entrained in the sheet feed direction.

  • Patent number: 5026762
    Abstract: Rubber compositions for tire treads of an all-weather type are disclosed which are so designed as to exhibit high dynamic Young's modulus, sufficient resistance to snow and ice skidding, to abrasion, to cracking and to crack growth and adequate durability. A selected base rubber is combined with a selected carbon black and a selected m-cresol resin. The base rubber is a blend of two different rubbers, one being natural rubber alone or a combination with a diene rubber and the other being butadiene rubber. The carbon black has specified absorptivity of iodine and dibutyl phthalate. The m-cresol resin is a novolak condensate.

  • Patent number: 4826911
    Abstract: Tread rubber compositions or use in automobile tires are disclosed which essentially comprise matrix rubbers and specified amounts of a selected class of low-hardness vulcanized rubbers having specified particle sizes. The matrix and vulcanized rubbers include carbon black, respectively, in amounts defined by the equation 0<X.ltoreq.Y/3 where X is the amount of carbon black present in the vulcanized rubber, and Y is the amount of carbon black in the matrix rubber, each such amount being based on the total weight of the matrix rubber. The resulting tire is rendered highly resistant to snowy and icy conditions and also to abrasive wear.
