  • Patent number: 7955383
    Abstract: A laminated stent encapsulated with a metal coating is provided. The metal coating may be a very thin metal coating. Portions of the metal coating may be removed such that the metal coating covers voids in the laminate, particularly in the area where the different layers of the laminated stent come together. The metal coating for the laminated stent may be provided by sputtering, such as vacuum deposition or ion beam sputtering, spraying, dipping, or other known methods.

  • Patent number: 7651527
    Abstract: A bioresorbable endoluminal prosthesis for placement in a body lumen having a stent substrate of a first metallic material that has a lower electrical potential than a standard reference electrode. The stent substrate is coated with a biodegradable polymer having a second metallic material dispersed therein, wherein the second metallic material has a higher electrical potential than the standard reference electrode. After implantation of the stent within the body lumen, the second metallic material is present in the polymeric coating in a sufficient concentration to cause galvanic corrosion of the first metallic material such that over time the stent substrate is bioresorbed.

  • Publication number: 20080319529
    Abstract: A stent includes a central portion having a first waveform. The first waveform is wrapped around a longitudinal axis of the stent at a pitch to define a plurality of helical turns. The stent also includes an end segment connected to one end of the central portion. The end segment has a second waveform that includes a plurality of struts and a plurality of crowns. Each of the plurality of struts has a different length so that peaks of the crowns that define an end of the stent lie within a plane that is substantially perpendicular to the longitudinal axis. Cross-sectional areas of the struts having different lengths vary so that the struts move substantially uniformly during radial contraction and/or radial expansion of the stent.

  • Patent number: 7318837
    Abstract: A balloon-expandable stent formed from a customized alloy formulation. The stent alloy has a either a high, variable or no work hardening rate, very high modulus of elasticity (Young's modulus), and a low yield point. A stent constructed of a material with this combination of properties undergoes significant plastic deformation upon deployment in vivo to its implantation diameter and exhibits minimum recoil for better sizing. The plastic deformation also raises the subsequent yield point of the stent material resulting in a stronger stent upon implantation that is more resistant to vascular loading.

  • Publication number: 20070244544
    Abstract: A valve replacement system that can be used for treating abnormalities of the right ventricular outflow tract includes a prosthetic valve device having a sealant contacting at least a portion of the outer surface of the valve device. The sealant may be breakable, and may be a hydrogel, an expandable hydrogel, or a solid. One embodiment of the invention includes a flowable sealant that is injected within the vascular system. Another embodiment of the invention includes a method for replacing a pulmonary valve that includes forming a seal around the exterior surface of a replacement valve and preventing blood flow around the replacement valve.
