  • Publication number: 20100112033
    Abstract: 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.

  • Publication number: 20080234662
    Abstract: Constructive disposal placed in artifon catheter applied in perforations above the papillae in fistula-papillotomy, where the procedure known as Endoscopic Retrograde Cholangiopancreatography (ERPC) is characterized by the combination of instrumental transpapillary access and the obtaining of contrasting images through pancreatic bile, a result obtained through the use of the artifon catheter device (A) claimed herein, which regards a perforation catheter above the papilla in fistula-papillotomy, to obtain access to biliary passages, making way for an alternative to known surgical techniques, this artifon catheter device (A) presenting a constructive concept composed of a Y connector component (1); a manipulating component of the concentric perforating tube (2); an external concentric tube component (3), within which a concentric perforation tube component (4) is located of which the far end is connected to a needle component (5); radiopaque marks components (6); a manipulating component of the external conce

  • Publication number: 20080077075
    Abstract: Constructive disposition introduced in indeflator equipment applied in coronary angioplasty intervention represented by an evolutionary solution translated by improvements of construction nature in the locking/unlocking system of the embolus, providing a better control over the injection or removal of liquids and/or fluids in a balloon catheter, being such locking/unlocking system (A) presents a simple construction concept, with bigger reliability and durability, making easy its assembling, with small quantity of pieces, minimizing the possibility of non-conform mechanical performance, and additionally providing easy handling by nurses and/or auxiliary people, being that the operation to inflate or to empty the balloon catheter with liquid or fluid is made possible by the embolus (B) movement over the syringe (D), through the application of a force to inflate (Fi) or to empty (Fe) in the hold element (C), through an embolus rotation, since to inflate the balloon the system must be locked, where to that the lo
