Abstract: An illustrative stent may comprise an elongated tubular member having a longitudinal axis, the elongated tubular member comprising at least one knitted filament forming a plurality of twisted knit stitches with intermediate rung portions extending circumferentially between radially adjacent twisted knit stitches. Each twisted knit stitch may be interconnected with a longitudinally adjacent twisted knit stitch forming a series of linked stitches. The elongated tubular member may be configured to move between a collapsed configuration and an expanded configuration, wherein in the collapsed configuration the series of linked stitches form longitudinal columns and in the expanded configuration the series of linked stitches extend helically around the elongated tubular member.

Abstract: A stent delivery device including an elongate shaft having a proximal region, a distal region and at least one lumen extending therein. The stent delivery device also includes a collapsible frame attached to the distal region of the elongate shaft. The collapsible frame includes a plurality of arms configured to surround a stent such that the plurality of arms define a stent containment region. The stent delivery device also includes an inner member extending within a least a portion of the stent containment region and an actuation member configured to actuate the plurality of arms of the collapsible frame from an expanded configuration to a collapsed configuration.

Abstract: An illustrative endoluminal implant having an elongated tubular member. The elongate tubular member having a proximal stent, a distal stent and an interconnecting sleeve. The proximal stent tapers from a first outer diameter adjacent the proximal end region to a second smaller outer diameter adjacent the distal end region. The distal stent has an outer diameter less than the first outer diameter of the proximal stent. The interconnecting sleeve is collapsible in response to an applied radial force such that the sleeve is positionable across a natural valve or sphincter.

Abstract: A lumen-apposing access system may include a catheter and a cauterization tip. The cauterization tip may include a biasing member and a cautery element. The cauterization tip may move relative to the catheter between a first position in which the cautery element is electrically inactive, and a second position in which the cautery element is electrically active. The biasing member biases the cautery element in the first position.

Abstract: A gastrointestinal assembly may be deployed within a patient's gastrointestinal tract in order to facilitate drainage of an abscess. The gastrointestinal assembly may include an outer stent and an inner stent disposed within the outer stent. The inner stent divides a volume within the outer stent into a primary passageway through which nutritional contents may pass and a secondary passageway protected from nutritional contents and configured to accommodate a passive drainage system for draining the abscess.

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 configured to move between a collapsed configuration and an expanded configuration. The elongated tubular member may comprise at least one twisted filament, such as a knitted filament having a plurality of twisted knit stitches with intermediate rung portions extending between adjacent twisted knit stitches, or a plurality of helical filaments twisted with a plurality of longitudinal filaments.

Abstract: The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to devices and methods for controlled delivery of a stent, such as a self-expanding stent, and more particularly for controlling the full deployment of a stent in incremental steps from a sheath and for controlling the reconstrainment of a stent in incremental steps within a sheath.

Abstract: Stent delivery device includes an inner member having a distal tip, a stent disposed over a stent receiving region of the inner member, an outer sheath slidable over the inner member, a stent sheath removably coupled to both the distal tip and a distal end of the outer sheath, and a stent expanding element attached to the distal tip and/or the distal end of the outer sheath. The stent expanding element is biased in an elevated position and aids expansion of the stent when the stent sheath is removed. The stent delivery device includes a proximal junction removably coupling the distal end of the outer sheath to the stent sheath, and a proximal junction removably coupling the stent sheath to the distal tip. Each of the proximal and distal junctions are separately actuatable to decouple the stent sheath from either the distal tip or the outer sheath.

Abstract: An example stent delivery system is disclosed. The example stent delivery system includes an inner shaft having a proximal portion, a distal portion and at least one lumen extending therein. The inner shaft further includes a stent receiving region disposed along the distal portion. The stent delivery system further includes a stent disposed along the stent receiving region. Additionally, the inner member includes a plurality of apertures disposed along at least a portion of the stent receiving region and the plurality of apertures are configured to permit fluid to flow therethrough and expand the stent.
