Patent number: 7993387Abstract: A method for making an implantable stent includes the steps of (i) providing a plurality of elongate stent wires; (ii) forming said wires into a hollow tubular structure having opposed first and second open ends; (iii) terminating said wires at the second end; (iv) aligning the wires at the second end into a plurality of mated adjacent wires to define a plurality of abutting regions; (v) welding the mated adjacent wires to one and the other at the abutting regions to define a plurality of welds; and optionally (vi) chemically or electro-chemically removing a portion of the welds. The method may further include the steps of (a) extending at least one of the mated stent wires to provide an extended stent wire; (b) looping the extended stent wire so the extended end abuts a proximal pair of stent wires; and (c) welding the extended and looped wire to the proximal pair of wires.Type: GrantFiled: May 14, 2004Date of Patent: August 9, 2011Assignee: Boston Scientific Scimed, Inc.Inventors: Claude O. Clerc, Paul K. Norton, Michael Zupkofska, Gary J. Leanna, George Tom Roberts

Publication number: 20110046719Abstract: A luminal endoprosthesis for treating aneurysms, particularly aneurysms located at an arterial bifurcation. One feature of the endoprosthesis is a tubular armature that can expand radially from a compressed state to an expanded state. A further feature of the endoprosthesis, when in the expanded state, is a lenticular head whom axis coincides with that of the tubular armature, and which can be inserted into an aneurysm pocket. A method of manufacturing such an endoprosthesis is also described.Type: ApplicationFiled: May 30, 2005Publication date: February 24, 2011Inventor: Noureddine Frid

Patent number: 7857844Abstract: An implantable stent includes a plurality of elongate wires braided to form a hollow tubular structure having a tubular wall to define an interior surface and an exterior surface and having opposed open first and second ends, wherein the opposed open first and second ends are atraumatic ends The atraumatic ends of the stent are desirably free of any loose wire ends. The wires include composite wires to enhance visibility of the wires to provide improved external imaging of the wires in the body. The elongate composite wires of the stent may be metallic wires having an outer metallic portion including a first metal, such as nitinol, and an inner metallic core portion including a second metal, which is a radiopaque material, such as gold, barium sulfate, ferritic particles, platinum, platinum-tungsten, palladium, platinum-iridium, rhodium, tantalum or combinations thereof.Type: GrantFiled: October 30, 2008Date of Patent: December 28, 2010Assignee: Boston Scientific Scimed Inc.Inventors: Paul K. Norton, Michael Zupkofska, Peter Brady, Gary L. Leanna, Claude O. Clerc, William Bertolino, Grainne Hanley

Patent number: 7846198Abstract: The present invention is directed to an implantable vascular prosthesis configured for use in a wide range of applications, such as treating aneurysms, maintaining patency in a vessel, and allowing for the controlled delivery of therapeutic agents to a vessel wall. The prosthesis comprises a helical proximal section coupled to a distal anchoring section having a generally zig-zag configuration. The prosthesis is configured to comply to a vessel wall without substantially remodeling the vessel, and further is configured to be precisely deployed in a vessel without shifting during deployment. The prosthesis also has a substantially small delivery profile compared to other known stents, while having an increased surface area to enhance delivery of therapeutic agents.Type: GrantFiled: January 13, 2003Date of Patent: December 7, 2010Assignee: NovoStent CorporationInventor: Michael Hogendijk

Patent number: 7758631Abstract: A bioabsorbable implantable endoprosthesis having elongate elements including hollow, cavity or porous portions adapted to accumulate by-product from the degradation of the bioabsorbable material and shortening the diffusion distance for water absorption and thereby relatively increasing the degradation of the structure.Type: GrantFiled: November 25, 2003Date of Patent: July 20, 2010Assignee: Boston Scientific Scimed, Inc.Inventor: Jonathan S. Stinson

Publication number: 20100063578Abstract: Embodiments of the present invention provide medical devices and methods for treating a target site within the body. For example, one embodiment provides a stent graft for treating a target site proximate to a bifurcated lumen, wherein the stent graft includes a first tubular structure having proximal and distal ends and a side wall extending therebetween. The first tubular structure includes an opening defined within the side wall and is configured to define a first portion having first and second ends and a second portion having first and second ends. The opening corresponds to the first ends of the first and second portions and the second ends of the first and second portions respectively correspond to the proximal and distal ends of the first tubular structure, and at least a portion of the first and second portions are configured to be positioned within respective branches of a bifurcated lumen.Type: ApplicationFiled: September 5, 2008Publication date: March 11, 2010Inventors: Brooke Ren, Daniel O.
