Patent number: 10925761Abstract: 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: GrantFiled: March 28, 2018Date of Patent: February 23, 2021Assignee: BOSTON SCIENTIFIC SCIMED, INC.Inventors: F.

Patent number: 9801742Abstract: 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: GrantFiled: June 4, 2014Date of Patent: October 31, 2017Assignee: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Claude O. Clerc, F. Anthony Headley, Jr., Forrest D. Whitcher, Suresh Gidwani
