    摘要: A balloon catheter having a multi-layered balloon which has a first layer and at least a second layer, and which has noncompliant limited radial expansion beyond the nominal diameter of the balloon. By selecting the polymeric materials forming the balloon layers, and arranging and radially expanding the multiple layers of the balloon in accordance with the invention, a balloon is provided having an improved low compliance, preferably in combination with high flexibility and softness.

    摘要: Tubing made of two or more polymers circumferentially arranged around the perimeter of the tubing in a single layer may be useful as medical tubing. Specifically, such tubing may be useful in catheters, sheaths, sheath introducers, implant delivery systems, and other medical devices having elongated tubular components. Selection of the two or more polymers based on the durometer and melting temperature permits optimization of axial strength and flexibility for particular applications. Such tubing may be extruded as a single layer tubing or a multi-layer tubing where the additional layers may be single material layers or more multi-polymer layers.

    摘要: A silicone composition having anti-microbial properties contains well distributed silica and nanoparticles of a noble metal. Silica and nanoparticles of a noble metal are added to liquid vinyl-terminated polydimethylsiloxane. A coupling agent is then added to the mixture and heated, the coupling agent comprising trialkoxysilane having a formula R1Si(OR2)3, wherein R1 is vinyl or allyl, and R2 is an alkyl radical having from 1 to 3 carbon atoms. In one embodiment, trimethylsiloxy terminated polymethylhydrosiloxane is then added to the mixture and heated in the presence of a catalyst so as to cross-link and cure the same into a silicone elastomer. In another embodiment, in place of the trimethylsiloxy terminated polymethylhydrosiloxane, a peroxide is added to mixture and heated to form the silicone. In this later example, no catalyst is needed.

    摘要: A method for producing a bioactive surface on an endoprosthesis, or on the balloon (3) of a balloon catheter (1) is described, wherein the surface (15) of the endoprosthesis, or the surface (4) of the balloon (3) is softened. The surface (15) of the endoprosthesis, or the surface (4) of the balloon (3) is moistened with a solution (6) of an active ingredient (7), and the solvent (8) is separated from the active ingredient (7). In addition, a balloon (3) of a balloon catheter (1) is disclosed, which comprises an uncoated surface (4), wherein an unencapsulated active ingredient (7) is embedded at least partially into the material of the surface (4). Furthermore, a balloon catheter (1) is described, which comprises a balloon (3) according to the invention. In addition, an endoprosthesis, particularly a polymer stent is described, which comprises an uncoated surface (15), wherein an active ingredient (7) is embedded at least partially into the material of the surface (15).
