摘要： An illustrative stent may include a tubular member defined by at least one knitted filament forming a plurality of twisted knit stitches with rungs extending circumferentially between radially adjacent twisted knit stitches, where each twisted knit stitch is interconnected with a longitudinally adjacent twisted knit stitch forming a series of linked stitches. The tubular member may be implanted to connect two spaced apart anatomical locations within the digestive tract, moving between a relaxed configuration and an elongated configuration. The tubular member has a first longitudinal length in the relaxed configuration and a second longitudinal length in the elongated configuration, and the first longitudinal length is less than the second longitudinal length.

摘要： The present invention relates to an endograft device (101) for treatment of ruptures (104.9) in one or more inner layers of a blood vessel (104), in particular, an aorta, comprising an anchoring unit (101.1) and a sleeve unit (101.2). The endograft device (101) defines an upstream endograft end (101.3) and a downstream endograft end (101.4), upstream and downstream being defined, in an implanted state of the endograft device (101), in relation to a general natural blood flow defining a blood flow direction within the blood vessel (104). The anchoring unit (101.1) is a collapsible unit located at the upstream endograft end (101.3), wherein the anchoring unit (101.1) is configured to anchor, in the implanted state, the endograft device (101) within the blood vessel (104) by engaging an inner surface of the blood vessel (104) with an expanded anchoring section (101.5). The sleeve unit (101.2) is located downstream of the anchoring unit (101.1), wherein the sleeve unit (101.2) is a thin- walled foldable element defining a longitudinal direction, a radial direction, a circumferential direction, an upstream sleeve unit end (101.7) and a upstream sleeve unit end (101.8). The sleeve unit (101.2) comprises an unsupported section (101.9) located at the upstream sleeve unit end (101.7), wherein the unsupported section (101.9) extends along the longitudinal direction and, at least in the implanted state, is unsupported over its entire circumference. The sleeve unit (101.2) is configured to be expanded, in the implanted state, to rest against an inner wall of the blood vessel (104) to sealingly cover the rupture (104.9) with the unsupported section (101.9).

摘要： A stent (100) can include outwardly facing protruding features (120) that facilitate engagement with a wall of a body vessel. The protruding features (120) can deploy from a frame (110) of the stent (100) to extend radially outwardly. When deployed into a body vessel, the protruding features (120) engage and anchor against the wall of the body vessel to ensure accurate and secure placement of the stent (100).

摘要： A medical device for treating a body lumen, such as a medical stent, includes an expandable scaffold configured to shift from a radially collapsed state to a radially expanded state. The stent includes a coating disposed along the outer surface of the expandable scaffold in which a portion of the coating includes a plurality of anti-migration members and one or more preferential separation regions. Each preferential separation region is configured to permit first and second regions of the coating to separate from one another along the preferential separation region therebetween as the expandable scaffold shifts from the radially collapsed state to the radially expanded state.

摘要： Side -branch, piercing stents and corresponding methods are provided. The stent body has apically controllably movable leaves that have a closed state and an open state, and at least one of the leaves has an apical piercing tip that is controllably moveable from a contracted state to an extended, piercing state, in which it pierces an apically adjacent element such as a main stent graft, an aneurism or a blood vessel, creates an opening therein, enables insertion of the apical tip of the side -branch stent and allows for spreading the leaves to anchor them within the element and ensure blood flow between the volume of the element and the side branches. Controlling element(s) control the movements of the tip(s) and the leaves to enable controlled and accurate positioning of the side -branch stent, its attachment to the main element and its anchoring therein.

摘要： Stents useable for treating venous stenosis are disclosed. In embodiments, a stent is configured to be auxetic, expanding axially as it is expanded radially, to prevent the imposition of tension on portions of a blood vessel adjacent to the stented portion of the blood vessel, and thereby prevent a narrowing of the adjacent portions and improving luminal gain. The stent may include one or more cross members that are deformable axially, to allow the axial length of the stent to be adjusted while maintaining a constant diameter, and further to allow the stent to be curved to conform to vessel curvature.
