Patent number: 8663314Abstract: The present invention relates to stent structures having improved migration resistance. In particular, the invention relates to mesh stents, such as braided or twisted stent designs, where at least a portion of the stent is folded back over itself to form a multi-layered stent device. Such multi-layered portions provide for migration resistance, among other advantages.Type: GrantFiled: February 14, 2012Date of Patent: March 4, 2014Assignee: Boston Scientific Scimed, Inc.Inventors: Mark Wood, Paul Norton, William Bertolino, F.

Publication number: 20140018901Abstract: A stent loading and deployment device includes an outer elongate tubular member having opposed proximal and distal ends and an inner elongate tubular member having opposed proximal and distal ends and slidably disposed within the outer tubular member. When the distal ends of the outer tubular member and the inner tubular member are axially aligned, a stent deployment region is defined there in between. The device further includes a stent loading member having opposed proximal and distal ends and slidably disposed between the outer tubular member and the inner tubular member. The distal end of the stent loading member is slidable to a distal position past the distal end of the outer tubular member for receiving a stent and is further slidable toward the proximal end of the outer tubular member to a location past the stent deployment region for disengagement of a stent from the stent loading member.Type: ApplicationFiled: September 16, 2013Publication date: January 16, 2014Applicant: Boston Scientific Scimed, Inc.Inventors: F.

Publication number: 20130231734Abstract: 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: March 29, 2013Publication date: September 5, 2013Applicant: Boston Scientific Scimed, Inc.Inventors: Claude Clerc, F.

Publication number: 20120017916Abstract: There is provided a device for performing a tracheotomy. The tracheostomy dilator has a body, tip and guiding catheter which are non-detachably attached to each other. The dilator has a cannula sized to accommodate a guide wire. After the trachea has been dilated, the entire device may be removed, leaving only the guide wire in the stoma, and a tracheostomy tube may be inserted over the guide wire and into the trachea. This substantially reduces the number of components and steps required for a successful tracheostomy procedure.Type: ApplicationFiled: July 26, 2010Publication date: January 26, 2012Inventors: James F.
