    摘要: Disclosed is an extracorporeal blood circulation device including a blood circulation circuit including a blood extraction line and a return line, a blood circulator in the circulation circuit and a control unit including a calculator arranged determining at least one parameter, recording it in a memory, and then comparing the standard value of the parameter with the recorded value. The device also includes a source of solution for liquefying blood clots, a device injecting and conveying the liquefaction solution in the circulation circuit, the control unit including a driver for the injector of the liquefaction solution. The control unit is arranged to actuate the driver when the value is exceeded, meaning that at least one clot has formed, the driver being arranged so that the liquefaction solution is present in the circulation circuit in an amount and for a time determined to be sufficient for liquefying the clot formed.

    摘要: This invention relates to stents coated with hydrophilic polymers containing S-nitrosothiols, which are able to provide local delivery of both nitric oxide and S-nitrosothiols by diffusion. This device is intended for coronary angioplasty applications with the purpose of inhibiting acute and chronic restenosis and refers to processes of stent coating with hydrophilic polymers containing incorporated S-nitrosothiols. This invention refers to an intracoronary implant device used in medical procedures, and introduces new S nitrosothiol-eluting stents coated with hydrophilic polymer multilayers. The hydrophilic polymers used for coating are polyvinyl alcohol, polyvinylpirrolidone and polyvinyl alcohol/polyvinylpirrolidone, polyvinyl alcohol/polyethylene glycol, polyvinylpirrolidone/polyethylene glycol and polyvinyl alcohol/polyvinylpirrolidone/polyethylene glycol blends. The S-nitrosothiols incorporated to the polymer coatings are mainly primary S-nitrosothiols, characterized by the fact of the nitric oxide (NO) molecule being covalently bound to a sulfur (S) atom which, in turn, is linked to a primary carbon in the molecule's structure, thus constituting the S—NO chemical group. The coating processes include immersion of the stents in polymer solutions containing S-nitrosothiols and nebulization processes of the polymer solutions containing S-nitrosothiols onto the stent surface.
