    摘要: An example stent delivery system is disclosed. The example stent delivery system includes an outer shaft having a distal end region, an inner surface and a lumen extending therein. The delivery system also includes an inner shaft extending within the outer shaft lumen, the inner shaft having a stent receiving region disposed along a distal end region thereof. Additionally, the delivery system includes a stent disposed along the stent receiving region and a braided member positioned radially outward from an outer surface of the stent and radially inward from the inner surface of the outer shaft, the braided member being attached to an outer surface of the inner member proximal of the stent. Additionally, the delivery system includes a plurality of tether members coupled to the braided member, wherein longitudinal retraction of the outer shaft relative to the inner shaft exposes the stent from the braided member.

    摘要: An endoprosthesis may include an expandable framework configured to shift between a delivery configuration and a deployed configuration, and a covering including a plurality of polymeric cover segments disposed about at least a portion of the expandable framework. A portion of each of the plurality of polymeric cover segments may be fixedly attached to the expandable framework. The plurality of polymeric cover segments is longitudinally spaced apart from each other in the delivery configuration. The plurality of polymeric cover segments longitudinally overlaps each other in the deployed configuration.

    摘要: An esophageal stent may include an expandable framework having a first end, a second end, and a central longitudinal axis extending from the first end to the second end, the expandable framework being configured to expand from a radially collapsed configuration to a radially expanded configuration, and a polymeric outer sleeve disposed radially outward of and spaced apart from a body region of the expandable framework. The expandable framework may include a plurality of anti-migration supports extending radially outward from the body region of the expandable framework toward the polymeric outer sleeve.

    摘要: An illustrative stent includes an elongated tubular member comprising at least one strut or filament forming a tubular wall having a plurality of cells extending through a thickness of the tubular wall. The elongated tubular member may be configured to move between a radially collapsed configuration and a radially expanded configuration. A coating is disposed on the elongated tubular member and spanning the plurality of cells. The coating forms a pocket within at least some of the cells of the plurality of cells and extends radially inward of the tubular wall to define a void. In some instances, a partition or wall is positioned within at least some of the pockets and transects the void.
