摘要： An anti-thrombogenic substance is immobilized on a base of a medical device to impart anti-thrombogenic properties to the medical device. The method comprises the steps of applying a photo-reactive azide derivative macromolecular material to a base to form a bonding layer, coating the bonding layer with a macromolecular layer composed of a water-soluble photo-crosslinking macromolecular material containing the anti-thrombogenic substance, and irradiating the base with ultraviolet light with the bonding layer and the macromolecular layer formed thereon to develop inter-molecular covalent bonding in the bonding layer. The macromolecular layer containing the anti-thrombogenic substance is thus fixed onto the base. Concurrently, the anti-thrombogenic substance is immobilized in the macromolecular layer which is crosslinked. The azide derivative can be poly-m-azidostyrene, copolymers, of poly-m-aziodstyrene with styrene and copolymers of poly-m-azidostyrene with methyl methacrylate. The water-soluble photo-crosslinking macromolecular material can be a copolymer of a photo-dimeric monomer with a water-soluble monomer or a copolymer of a photo-reactive azide with a water-soluble monomer.

摘要： An apparatus for separating a balloon from a catheter member of a balloon is capable of melting and breaking a heat-meltable connecting member through which the balloon is connected to the catheter body by causing an electric current to flow between at least a pair of electrodes arranged on or in the vicinity of the connecting member. The apparatus has impedance measuring means for measuring the impedance of an electrode circuit including a pair of electrodes and lead lines connected to the electrodes, and judging means for comparing the measured value of the impedance with a predetermined reference range and capable of producing an abnormal signal when the measured value of the impedance does not fall within the predetermined reference range. The apparatus enables the operator to judge whether the electrode circuit is in safe condition, before changing the balloon with a settable liquid and to charge a settable liquid into the balloon only when the safe condition of the electrode circuit is confirmed, so that the balloon after the setting of the liquid can be separated from the catheter body without fail, thus eliminating any risk for the catheter body to dangerously remain in the living body.

摘要： Photocurable glycosaminoglycan (GAG) derivatives and crosslinked glycosaminoglycans, which are highly safe and biocompatible, a method of preparing such photocurable GAG derivatives readily moldable by casting using a solvent when desired, by which method unreacted substances causative of adverse effects can be readily eliminated, and a method of producing the crosslinked GAGs and medical materials based on the photocurable GAG derivatives or crosslinked GAGs are provided. The photocurable GAG derivatives comprise a glycosaminoglycan and a photoreactive compound bound thereto and can be produced, for example, by subjecting hydroxyl or carboxyl groups of the glycosaminoglycan to esterification reaction or amidation reaction, respectively, with the photoreactive compound. The crosslinked GAGs are derived from the photocurable GAG derivatives by intermolecular crosslinking of the photoreactive compound bound thereto.
