Abstract: A stent includes an elongated tubular member formed from at least one filament, the elongated tubular member including a first segment in which the at least one filament is knitted into a first knitted pattern providing the first segment with a first performance characteristic and a second segment in which the at least one filament is knitted into a second knitted pattern providing the second segment with a second performance characteristic different from the first performance characteristic. Either the first knitted pattern or the second knitted pattern includes a plurality of anti-migration loops that extend radially outwardly from the elongated tubular member.

Abstract: A medical device, comprising a tube having a sidewall defining a lumen within the tube, wherein a plurality of openings extend through a distal portion of the sidewall and are in fluid communication with the lumen; a support structure coupled to the distal portion of the sidewall, the support structure having a contracted configuration and an expanded configuration, and the support structure having support openings through a wall of the support structure; and a porous body over at least a portion of the support structure.

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: 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.
