Abstract: A stent configured to change in length while maintaining a constant inner diameter is disclosed. The stent includes an elongated tubular member comprising at least one knitted filament forming a plurality of twisted knit stitches with rungs extending circumferentially between adjacent twisted knit stitches, wherein each twisted knit stitch is interconnected with a longitudinally adjacent twisted knit stitch forming a series of linked stitches. The tubular member is configured to be stretched from a first length to a second length while in a radially expanded configuration without substantially changing the inner and/or outer diameter of the tubular member.

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.

Abstract: A braided stent having a plurality of retrieval and/or repositioning levers includes a stent body formed of a plurality of wires interbraided in a braided pattern. The repositioning and/or retrieval levers have a loop portion extending radially away from the stent body and first and second legs extending along the stent body. The levers are configured to be actuated radially inward toward the central longitudinal axis of the stent by a radially inwardly directed force to radially collapse the stent.

Abstract: A stent delivery device having a delivery configuration for delivering a stent to a treatment location and a deployment configuration for deploying the stent at the treatment location may include an outer sheath, an inner shaft slidably disposed within a lumen of the outer sheath, and a distal tip member fixedly attached to a distal end of the inner shaft. A distal portion of the outer sheath may include a plurality of longitudinal strips circumferentially disposed about the lumen of the outer sheath. At least a portion of the distal tip member may be configured to slide over a distal end of the outer sheath in the delivery configuration.

Abstract: A stent includes a tubular body formed of one or more interwoven wires, the tubular body having first and second opposing open ends and a lumen extending therebetween. The stent further includes a first anchor member disposed adjacent the first open end and a second anchor member disposed adjacent the second open end, the first and second anchor members each extending radially outward from the tubular body, the first and second anchor members each having an outer diameter larger than an outer diameter of the tubular body disposed between the first and second anchor members. A plurality of spacer members are disposed around the first open end and extending longitudinally beyond the first open end, wherein when a pulling force is applied to the spacer members, the outer diameter of the tubular body is not reduced.

IPC: A61F5/445
Abstract: A stent formed of a radially-outwardly expandable material to exert a radially expansive force to inhibit migration. The stent includes a retention member configured to retain the stent in place relative to the body lumen in which the stent is placed. The retention member may further contribute to inhibiting migration of the stent and/or tissue at which the stent is deployed. Various features may be provided on the retention member to adapt the stent for use with a stoma and/or ostomy appliances or other particular locations in the body benefiting from the stent.

Abstract: The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to delivery systems configured to position a distal portion of a medical device within a restricted anatomical area. In one example, a delivery system may include a flexible elongate member with an inner member within a lumen of the flexible elongate member. A stent may be constrained therebetween. The stent may be configured to move between a first configuration to a second deployed configuration when unconstrained from the flexible elongate member. When the stent moves from the first configuration to the second configuration, the inner member may change from a first length to a second, shorter length. Other embodiments are contemplated.

Abstract: An implantable stent may include a braided tubular member formed of braided wires and including radially outward wire segments crossing over and positioned radially outward of radially inward wire segments at a plurality of crossover points. Also, the radially outward wire segments may be coated with a coating and the radially inward wire segments may be uncoated and devoid of the coating.

Abstract: Stent delivery device including an inner member having a distal tip, a stent support member, and a stent disposed over a stent receiving region of the stent support member. An elongated outer sheath is slidably disposed over the inner member and the stent. The stent delivery device includes a distal junction removably coupling the distal end of the outer sheath to the distal tip, where the distal junction is actuatable to decouple the outer sheath from the distal tip. The stent delivery device includes a proximal junction removably coupling a distal portion of the outer sheath to a proximal portion of the outer sheath, where the proximal junction is actuatable to decouple the distal portion of the outer sheath from the proximal portion of the outer sheath. The distal and proximal junctions may be separately actuatable by rotating the inner member relative to the proximal portion of the outer sheath.

Abstract: An example medical device is disclosed as an expandable stent. The stent includes a tubular scaffold having an inner surface, an outer surface, and a lumen extending therein. The expandable stent also includes a liner disposed within the lumen of the tubular scaffold. Further, the liner is radially spaced from a medial region of the tubular scaffold to define a tissue ingrowth region along an uncovered portion of the medial region. Additionally, the liner extending along the tissue ingrowth region is configured to limit the amount of tissue ingrowth along the medial region of the scaffold.
