Abstract: A vasodilating catheter is disclosed which is characterized by using a triple-flow catheter tube and allowing two of the three flow paths formed by the catheter tube to communicate with a balloon. Owing to this configuration, the air entrapped inside the balloon can be easily removed and, as the result, the otherwise inevitable degradation of the balloon's opacitying property is precluded and the angioplasty is performed with increased safety and ease.

Abstract: In a device for loading a tape-like substance, in which the tape-like substance, such as tape, film or the like paid out of a supply reel is conveyed with air to a take-up reel's side through a duct as a tape path having a peripheral path provided along the periphery of a guide drum, a movable guide for leading the tape-like substance together with the air to the beginning of the peripheral path is disposed, so that it can be smoothly operated to load the tape-like substance.

Abstract: A catheter for the repair of an injured blood vessel, characterized by comprising a multiple-lumen type catheter tube having at least two tubular cavities, at least one dilating member disposed in the distal portion of said catheter tube and adapted to communicate with one of said tubular cavities, a lateral hole for the injection of a blood coagulation accelerant disposed on said catheter tube at the proximal side than said dilating member side and adapted to communicate with the other tubular cavity, and a hub having a plurality of flow conduit communicating severally with said tubular cavities of said catheter tube and adapted to communicate with the proximal portion of said catheter tube.

Abstract: In a device for loading a tape-like element, such as, a magnetic tape, film or the like, in an apparatus having supply and take-up reels which are disposed side-by-side with their axes substantially horizontal in a normal operating position of the apparatus, and a guide drum located under the supply reel in such normal operating position; a generally zig-zag path for the tape-like element is provided with an inlet adjacent the supply reel for receiving the tape-like element paid out from the latter and an outlet arranged near to the take-up reel, such path includes a supply side path portion extending from the inlet to a peripheral path portion around at least a part of the periphery of the guide drum and a take-up side path portion extending from the peripheral path portion to the outlet, the supply side, peripheral and take-up path portions have respective lower wall sections facing upwardly in the normal operating position of the apparatus, and air under pressure is introduced into the path of the tape-lik

Abstract: In a device for loading a tape-like element, such as, a magnetic tape, film or the like, from supply reel to take-up reel, a tape path for the tape-like element is formed from the vicinity of the supply reel to the vicinity of the take-up reel, a rotation detector is connected with the supply reel to detect the rotation of a predetermined angle in the supply reel and generates a control signal therefrom, and a blower is provided to introduce air under pressure into the tape path for conveying the tape-like element along the tape path in response to the control signal.

Abstract: A structural arrangement for members to be operated for control over varied functions of a camera, such as operation buttons, terminals for connection with accessories, etc. A grip part is openably carried by one side of a camera body. A camera function control arrangement is disposed within the grip.
