Abstract: Medical devices and methods are disclosed in the present application. In one illustrative example a tissue removal device may comprise an elongate shaft defining a lumen and having a proximal end and a distal end, wherein a proximal portion of the elongate shaft has a first diameter and a distal portion of the elongate shaft has a second diameter, and wherein the first diameter is less than the second diameter and an elongate member disposed at least partially within the elongate shaft, the elongate member having a proximal end and a distal end, the distal end of the elongate member comprising a cap. In some further embodiments, the elongate member may be axially translatable between a proximal position and a distal position, and the cap may form a closed receptacle with the distal portion of the elongate shaft when the elongate member is in the proximal position.

Abstract: A medical stent includes a central stent segment, a proximal stent segment adapted to be positioned over a proximal region of the central stent segment, and a distal stent segment adapted to be positioned over a distal region of the central stent segment. A polymeric coating extends over the proximal stent segment, the distal stent segment and at least a portion of the central stent segment, the polymeric coating adapted to allow the proximal stent segment to float over the proximal region of the central stent segment and to allow the distal stent segment to float over the distal region of the central stent segment. Upon implantation, the central stent segment is adapted to translate relative to the proximal stent segment and the distal stent segment in response to peristaltic forces.

Abstract: The present disclosure provides medical devices such as self-expanding stents or tissue lumen stents with an overlapping layer. The medical devices can have a coating or cover disposed over all or a portion of the medical device. The overlapping layer define a doubled back portion at an end of the medical device that includes an elongate section to provide dynamic movement of the end of the medical device relative to a central portion of the medical device.

Abstract: Example medical stents are disclosed. An example stent includes a tubular framework including an inner surface, an outer surface and a lumen extending therethrough. Additionally, the stent includes a tissue ingrowth scaffold extending along a portion of the outer surface of the tubular framework, wherein the tissue ingrowth scaffold is spaced radially away from the outer surface of the tubular framework to define an expansion cavity therebetween and wherein the tissue ingrowth scaffold permits tissue ingrowth along a portion thereof. Further, the stent includes an expandable member positioned within at least a portion of the expansion cavity.

Abstract: An illustrative stent may comprise an elongated tubular member having a first end and a second end and an intermediate region disposed therebetween. The elongated tubular member may include at least one barb attached thereto. The barb may be configured to be tucked under a filament of the stent during delivery of the stent and protrude radially from the stent, when the stent is deployed.

Abstract: An endoprosthesis includes an elongated tubular member including a filament forming circumferential rows having a plurality of knitted loops and intermediate rungs extending between adjacent knitted loops. The tubular member includes at least one window and may include a plurality of anti-migration loops adjacent the at least one window and configured to shift between first and second positions when unconstrained. Making the endoprosthesis includes forming the plurality of knitted loops and intermediate rungs in a first row of loops and rungs, extending the filament to form a second row of loops and rungs interwoven with the first row, and forming the at least one window without cutting the filament. Placing the endoprosthesis includes positioning the endoprosthesis within a body lumen adjacent a branch lumen, expanding the tubular member to span the branch lumen, and shifting at least some anti-migration loops toward the second position and into the branch lumen.

Abstract: The disclosure provides a tissue lumen stent that has an elongated tubular configuration and a foreshortened configuration in which the upstream, the downstream, or both the upstream and downstream ends expand radially into flanged and/or flared structures while the region therebetween is generally cylindrical. The upstream flange structure has a larger maximum lateral dimension, axial width and/or axial radius than that of the downstream flange structure and may include an inclined portion having an axial length at least as long as a maximum diameter of the saddle region when the body is in the foreshortened configuration.
