| 20090048667 | Controlled Drug-Release Composition and Drug-Releasable Medical Device - A drug-releasable medical device contains a controlled drug-release composition comprising 100 parts by weight of an organic polymeric material which is soluble in an organic solvent and insoluble in water, 5 to 60 parts by weight of a lipid-soluble, low molecular weight release auxiliary agent and 1 to 70 parts by weight of a drug. When the composition is applied on a stent, a catheter, an organ replacement medical device, an artificial organ or the like in the form of coating or the like, the medical device is provided with a drug release function. Argatroban or sarpogrelate hydrochloride or both of them are gradually released from the surface of a stent for treating coronary artery stenosis, for example. In order to exhibit a sustained-release function for a desired period of time, the drug to be gradually released is carried in a polymeric material coated on a surface of a metal forming the stent or in a porous stent substrate. | 02-19-2009 |
| 20100198344 | SUSTAINED DRUG-RELEASING STENT - A stent includes a stent body of a cylindrical configuration having outer and inner surfaces, a first coated layer coating at least the outer surface, and a second coated layer coating substantially completely over the first coated layer. The first coated layer is prepared of a first composition comprising a polymer and a vascular intimal hyperplasia inhibitor (preferably argatroban) of a kind, which does not inhibit proliferation of endothelial cells, the weight compositional ratio of the polymer to the inhibitor being within the range of 8:2 to 3:7. On the other hand, the second coated layer is prepared of a polymer alone or a second composition comprising a polymer and a drug, the weight compositional ratio of the drug to 80% by weight of the polymer being less than 20% by weight. | 08-05-2010 |

| 20080237098 | MAGNETIC SEPARATION FILTERING AND CLEANING APPARATUS - A magnetic separation filtering and cleaning apparatus for adding flocculant and magnetic powder to raw water containing pollutant particles to form magnetic floc in treated fluid and separating and removing the magnetic floc from the treated fluid, comprising: a magnetic field generation device being provided in a rotating body for suctioning the magnetic floc on a surface of the rotating body from the treated fluid containing the magnetic floc, a magnetic field rotating device for rotating the magnetic field generation device, a sludge recovery device for separating sludge including the magnetic floc mechanically from the surface of the rotating body of the magnetic field generation device; and a filtering device having a rotating net for filtering out the magnetic floc from the treated fluid including the magnetic floc and flowing down the treated fluid filtered through the rotating net. | 10-02-2008 |
| 20080245739 | TREATMENT METHOD OF ORGANIC COMPOUNDS INCLUDED IN WASTE WATER, A TREATMENT APPARATUS OF ORGANIC COMPOUNDS INCLUDED IN WASTE WATER, A TREATMENT SYSTEM OF ORGANIC COMPOUNDS INCLUDED IN WASTE WATER, AND A BITUMEN COLLECTING SYSTEM - A treatment method of organic compounds included in waste water, comprising the steps of: | 10-09-2008 |
| 20090215161 | MICROORGANISM TESTING DEVICE AND CHIP FOR TESTING MICROORGANISMS - There is disclosed a microorganism testing device in which various types of microorganisms can be easily concentrated. The microorganism testing device includes a detection chip, a carrier device, a controller, and a magnet. The detection chip includes a specimen container for holding a specimen containing microorganisms, a trapping particle liquid container for holding trapping particle liquid containing magnetic particles, a microorganism trapping section for trapping the microorganisms, and a liquid flow path. In a state where a magnetic force of the magnet acts on the microorganism trapping section, the controller controls the carrier device to flow the trapping particle liquid into the microorganism trapping section to form a filtration filter by trapping plural magnetic particles in the microorganism trapping section, and in this state, to flow the microorganisms into the microorganism trapping section so that the microorganisms within the specimen are deposited on one side of the filtration filter. | 08-27-2009 |
