Abstract: A medical instrument may include a tube, a sheath provided around and coaxial with the tube, and an inflatable balloon at a distal end of the sheath. The balloon may receive a fluid from a lumen of the sheath, and may have a central opening along a longitudinal axis thereof, and into which the tube extends, a proximal portion, a middle portion adjacent to and distal of the proximal portion, and a distal portion adjacent to and proximal of the middle portion. When the balloon is inflated with the fluid, a maximum diameter of the middle portion may be less than a maximum diameter of the proximal portion, and less than a maximum diameter of the distal portion. The medical instrument may also include an extraction member provided at a distal end of the tube, distal to the balloon, and movable axially relative to the balloon.

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: The present disclosure relates generally to stents and methods for managing passage of material through a body lumen. In some embodiments, a medical stent may include a stent body defined by a hollow tubular elongate structure extending along a central axis, the stent body including a first portion and a second portion. The medical stent may further include a control region between the first and second portions, wherein in a first configuration the hollow tubular elongate structure of the control region is in a closed, twisted configuration, and wherein in a second configuration the hollow tubular elongate structure of the control region is in an open, expanded configuration.

Abstract: A device for occluding flow of materials is formed as a simple structure permitting a compact delivery configuration which may shift to an expanded deployment configuration. The device has at least one expandable portion formed of a plurality of elongated longitudinally extending frame elements. The frame elements may be spaced apart to define spaces therebetween, and a flexible occlusive material may be provided to block flow of material through such spaces. A flexible occlusive material may form one of two expandable portions of the device without the need for frame elements.

Abstract: Devices, systems, and methods for treating wounds in endoluminal spaces of a patient are disclosed. A device may include an elongate tube defining a proximal end, a distal end, and a lumen, an expandable component adjustably positioned at the distal end of the elongate tube, and a tether coupled to the expandable component and extending proximal from the expandable component through the lumen to a location exterior of the elongate tube. The expandable component may be adjustable between a delivery position within the elongate tube and a fully deployed position at least partially exterior of the elongate tube. The expandable member may be absorbent. A proximal end of the elongate tube may couple to a vacuum source to apply a negative pressure at or proximate the expandable component. An inner member may extend through the elongate tube and be configured to adjustably engage the expandable component.

Abstract: An endoprosthesis includes an elongated tubular member including a filament forming circumferential rows having a plurality of knitted loops and intermediate rungs extending between adjacent knitted loops. The tubular member includes at least one window and may include a plurality of anti-migration loops adjacent the at least one window and configured to shift between first and second positions when unconstrained. Making the endoprosthesis includes forming the plurality of knitted loops and intermediate rungs in a first row of loops and rungs, extending the filament to form a second row of loops and rungs interwoven with the first row, and forming the at least one window without cutting the filament. Placing the endoprosthesis includes positioning the endoprosthesis within a body lumen adjacent a branch lumen, expanding the tubular member to span the branch lumen, and shifting at least some anti-migration loops toward the second position and into the branch lumen.

Abstract: An esophageal stent may include an expandable framework having a first end, a second end, and a central longitudinal axis extending from the first end to the second end, the expandable framework being configured to expand from a radially collapsed configuration to a radially expanded configuration, and a polymeric outer sleeve disposed radially outward of and spaced apart from a body region of the expandable framework. The expandable framework may include a plurality of anti-migration supports extending radially outward from the body region of the expandable framework toward the polymeric outer sleeve.

Abstract: An illustrative stent includes an elongated tubular member comprising at least one strut or filament forming a tubular wall having a plurality of cells extending through a thickness of the tubular wall. The elongated tubular member may be configured to move between a radially collapsed configuration and a radially expanded configuration. A coating is disposed on the elongated tubular member and spanning the plurality of cells. The coating forms a pocket within at least some of the cells of the plurality of cells and extends radially inward of the tubular wall to define a void. In some instances, a partition or wall is positioned within at least some of the pockets and transects the void.
