Abstract: Disclosed is a device for sheet insertion includes: a cylindrical mantle tube of which the front and back ends are opened and the inside is formed to be a sheet receiving part and an extruding member for sheet extrusion that is inserted into the mantle tube in a state of moving in a back and forth direction that is a tube-axis direction and of rotatable, wherein the extruding member has a shaft having a longer length than that of the mantle tube and a forked sheet winding part disposed at a tip portion of the shaft, and axial slits having a size enough to insert the sheet are formed therethrough on walls facing each other at the front end of the mantle tube over approximately the same length as that of the sheet winding part.

Abstract: A balloon catheter having a purge hole according to the present invention is configured with a duplex tube structure of an inner tube and an outer tube both of which having an opening at the distal end thereof. A balloon is provided to stretch over the section between the distal ends of the inner tube and the outer tube. A purge hole is provided on the inner tube covered by the balloon, through which the remaining air inside the balloon lumen and the balloon is discharged to a main lumen formed in the inner tube when the balloon is expanded, and which is closed by the balloon when the balloon is contracted.

Abstract: A water evacuating tube for washing an electric knife of the present invention includes a heat resistant tube main body, in which front and rear ends are open, and an inside in an axial direction is a hollow portion in which the electric knife is disposed and held. In a peripheral wall of the tube main body, a lumen for pouring water is disposed in the axial direction, and a front end portion of the tube main body is provided with a pouring water aperture for dropping the water from the lumen onto an electrode of the electric knife.

Abstract: A gas exchange apparatus for use as a artificial lung incorporates a hollow fiber module for bundling a plurality of thin-walled hollow silicone fibers. The fibers are wound in the form of a twilled pattern so as to form an internal perfusion passage and an external perfusion passage. A housing encloses the hollow fiber module. The housing incorporates a first inlet and outlet formed on the housing for communication of gas or liquid with the internal perfusion passage, and a second inlet and outlet formed for communication of gas or liquid with the external perfusion passage.

Abstract: Disclosed is a small-sized gas exchange apparatus of high performance having an increased gas exchange rate and a reduced priming volume, comprising a hollow fiber module M.sub.1 formed by bundling a plurality of silicone membrane hollow fibers 1 wound in the form of a twilled pattern, a housing H.sub.1 for enclosing the hollow fiber module, an internal perfusion passage and an external perfusion passage formed within the housing H.sub.1, a first inlet A and a first outlet B formed on the housing for gas or liquid for communication with the internal perfusion passage, and a second inlet C and a second outlet D formed on the housing for gas or liquid for communication with the external perfusion passage.

Abstract: A stent for intracorporeal retention is inserted in a human body, for instance, inside an airway, esophagus, or bile duct, and used for preventing a bore of the internal organs described above from being occluded. With this stent, discharge from the airway does not easily adhere to, nor deposit on, the internal surface of the cylindrical body, so that the occlusion thereof can effectively be prevented and, at the same time, granulation does not easily occur and, for this reason, occlusion of the airway can be prevented, which insures a high degree of safety for a human body.

Abstract: A thermoplastic resin-silicone rubber composite shaped article comprising (a) a shaped article of a thermoplastic resin selected from the group consisting of soft vinyl chloride resins, olefin resins, urethane resins and styrene resins and (b) a cured layer of an addition polymerization type silicone rubber composition adhering to the one or both surfaces of the shaped article of a thermoplastic resin. To the surface of the above shaped article of a thermoplastic resin to which the above cured layer of an addition polymerization type silicone rubber composition does not adhere, there may adhere another cured layer of the above addition polymerization type silicone rubber composition. To either or both of these cured layers, there may further adhere a layer of the above thermoplastic resin, other thermoplastic resin, a silicone rubber, a silicone resin, glass, ceramics or a metal.

Abstract: This invention relates to a medical sealant comprising polyorganosiloxane gel for sealing a junction part between living skin and a medical instrument penetrating through the skin, said polyorganosiloxane gel having a partially cross-linked three dimentional structure expressed by the basis general formula ofR.sub.n SiO.sub.(4-n)/2(wherein R represents hydrogen or monovalent hydrocarbonyl group and n represents an integer of 1 to 3), characterized in that said gel self-supports its figure at room temperature and has a hardness expressed by a loading weight of 1 g to 250 g by which a disc of a diameter of 10 mm sinks to 1.0 mm on the gel.

Abstract: A soft vinyl chloride resin-silicone composite shaped article consisting of a soft vinyl chloride resin shaped article and a cured layer of an addition polymerization type silicone composition adhered to the surface of the vinyl chloride resin shaped article, wherein said addition polymerization type silicone composition contains an organohydrogenpolysiloxane having at least two hydrogen atoms directly bonding with silicon atoms in each molecule, in an amount enough to provide one to six such hydrogen atoms per one vinyl group of the silicone composition. The above composite shaped article has a very high bonding strength between the vinyl chloride resin shaped article and the cured layer of an addition polymerization type silicone composition.
