Abstract: A delivery system for delivering an implant having both a rigid portion and a flexible portion to a body lumen. The delivery system includes an outer tubular member and an inner tubular member slidably disposed within the lumen of the outer tubular member. The inner tubular member includes at least one opening positioned in a side wall adjacent to a distal end region. An expandable implant, including a rigid portion and a flexible portion, is disposed about the outer surface of the inner tubular member. A distal portion of a thread is wrapped around the flexible portion of the implant and configured to maintain the flexible portion in a radially collapsed configuration during delivery of the implant. A distal end region of the outer tubular member is disposed around the rigid portion of the implant to maintain the rigid portion in a radially collapsed configuration during delivery of the implant.

Abstract: An illustrative endoluminal implant having an elongated tubular member. The elongated tubular member having a stent and a retrieval suture interwoven with the stent. The retrieval suture including a first suture loop extending about a circumference of the stent and adjacent to a suture retrieval loop and a second suture loop extending about a circumference of the stent and longitudinally spaced from the first suture loop. The first and second suture loops coupled via one or more interconnecting segments. At least one of the first or second suture loops has an arc length of less than 270° of the circumference of the stent.

Abstract: An example medical device for treating a body lumen is disclosed. The medical device includes an expandable scaffold including first and second regions, each of the first and second regions include a plurality of interstices located therein. The medical device also includes a covering spanning each of the plurality of interstices of the first region. The second region is free of the covering. A biodegradable gripping material is disposed on an outer surface of the covering. Further, the expandable scaffold is configured to shift from a collapsed state to an expanded state and the second region is configured to contact an inner surface of the body lumen in the expanded state. Additionally, the gripping material is designed to initially prevent migration of the expandable scaffold upon implantation in the body lumen until the second region is secured to the inner surface of the body lumen.

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: A mandrel for forming a stent with a tapered profile and one or more anti-migration features includes a first stent shaping segment having a first diameter, a second stent shaping segment having a second diameter less than the first diameter and a tapered segment disposed therebetween. A third stent shaping segment is releasably securable to the second stent shaping segment and has a third diameter greater than the second diameter. One or more movable pins are outwardly extendable from corresponding apertures formed within the tapered segment. An actuation element is engagable with the first stent shaping segment and includes a tapered surface configured to engage the one or more movable pins and support the one or more movable pins extended from the corresponding apertures.

Abstract: A medical stent having a first end, a second end, and a central longitudinal axis extending from the first end to the second end, may include a plurality of first filaments each extending in a first helical path around the central longitudinal axis in a first direction and a plurality of second filaments each extending in a second helical path around the central longitudinal axis in a second direction. The plurality of first filaments may be interwoven with the plurality of second filaments. The first helical path of at least one of the plurality of first filaments may include a circumferential offset disposed between the first end and the second end.

Abstract: A system for treating a body lumen including a first stent configured to be positioned in a body lumen and a second stent configured to be positioned in the lumen of the first stent prior to removing the first stent from the body lumen. The first stent includes a liner disposed radially inward of the tubular scaffold of the first stent to permit tissue ingrowth within a tissue ingrowth region defined between the liner and the tubular scaffold. The retrieval stent is configured to be expanded within the previously implanted first stent to cause tissue to recede from the tissue ingrowth region to facilitate removal of the first stent from the body lumen.
