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 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 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: 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: Polypectomy devices and methods for making and using polypectomy devices are disclosed. An example polypectomy device may include an elongate sheath having a proximal end and a distal end. A handle assembly may be coupled to the proximal end. The handle assembly may include a first actuator and a second actuator. A first shaft may extend through the sheath and may be coupled to the first actuator. An end effector may be coupled to the first shaft. A second shaft may extend through the sheath and may be coupled to the second actuator. A retention member may be coupled to the second shaft. The first actuator may be designed to shift the end effector between a housed configuration and a deployed configuration. The second actuator may be designed to shift the retention member between a retracted configuration and a holding configuration.

Abstract: A knitted stent extending along a central longitudinal axis may comprise a filament forming a plurality of cells arranged in a plurality of columns and a plurality of rows. The plurality of rows may extend parallel to the central longitudinal axis. The plurality of columns may extend circumferentially around the central longitudinal axis. The plurality of rows may include a plurality of loop rows and a plurality of rung rows interposed between adjacent loop rows. Each cell within the plurality of loop rows may include a circumferential loop element connected to two longitudinally oriented connector elements. The plurality of rung rows may include a plurality of circumferential rung elements connected to adjacent loop rows. A majority of the plurality of loop rows may include open cells having an open end. At least one of the plurality of loop rows may include a plurality of closed cells having a closed end.

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.
