Publication number: 20090132025Abstract: A composite stent structure includes separate and distinct stent elements or members: an outer stent element and an inner stent element removably attached to the outer stent element. The outer element may be, for example, a bioabsorbable stent typically constructed of a relatively non-resilient material such that the outer bioabsorbable stent element may not be self-expanding and subject to migration within the lumen over time. In contrast, the inner element may be, for example, a removable SEMS used to urge and maintain the outer element in position in the body lumen. The temporary inner SEMS may retain the composite structure (including the underlying inner element) in position until such time as the outer element is appropriately incorporated into the surrounding tissue or some other criteria occurs such that the removal of the SEMS is indicated. The SEMS may then be detached from the outer element and removed from the body lumen.Type: ApplicationFiled: January 30, 2009Publication date: May 21, 2009Inventors: Peter J. Shank, F. Anthony Headley, JR.

Publication number: 20080300673Abstract: The invention relates to an implantable radiopaque stent adapted to be disposed in a body lumen. In one aspect of the invention, a plurality of elongate filaments including one or more radiopaque filaments are arranged to form a hollow tubular structure having a tubular wall that defines an inner surface and an outer surface and opposing first open end and second open end. One of the open ends of the stent is formed by an intersection of adjacent filament ends. A radiopaque compound is applied to the intersection, the radiopaque compound comprising radiopaque material and polymeric material. The radiopaque compound and radiopaque filament provide improved external imaging of the tubular structure on imaging equipment.Type: ApplicationFiled: April 2, 2008Publication date: December 4, 2008Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Claude Clerc, F.

Patent number: 6090108Abstract: A bipolar endoscopic scissors is provided with scissor blades where at least one scissor blade is coated with an electrically non-conductive ceramic from its cutting edge along at least a contiguous portion of its shearing surface. The coated blade is provided with a cutting edge having an obtuse included angle which is preferably between approximately 95.degree.-140.degree., and more preferably between 110.degree. and 120.degree.. The blades according to the invention may be configured in several different ways with regard to the number of layers and types of material used, the extent of the ceramic coating, and whether one or both blades are configured in an identical manner. The blades according to the invention having cutting edges defined by obtuse angles cut well and provide a good cutting feel to the practitioner while preventing the ceramic coating from chipping at the cutting edge.Type: GrantFiled: July 17, 1997Date of Patent: July 18, 2000Assignee: Symbiosis CorporationInventors: Michael Sean McBrayer, F.
