Abstract: A filament cutting device may include an outer sheath. A bushing may be coupled to a distal end of the outer sheath. An inner diameter of the bushing may be a cutting edge at a distal tip of the bushing. An actuation wire may be slidably extendable within the outer sheath and bushing. An engaging body may be coupled to a distal end of the actuation wire. A cavity may be defined along a length of the engaging body configured to capture a portion of the filament within the cavity. Movement of the actuation wire and engaging body with the filament captured within the cavity may cause the cutting edge to sever the filament.

Abstract: A tissue traction device having a segment defined along a limited extent about the perimeter of the tissue traction device and more flexible than surrounding regions of the tissue traction device. The tissue traction device is actuatable to bend along the more flexible segment thereof, generally in a direction of a side of the tissue traction device opposite the more flexible segment thereof. The tissue traction device may be formed from one or more flexible tubular elements, with the flexible segment along a limited extent about the perimeter of the one or more tubular elements. A tissue traction system may be configured to provide actuation medium, such as an inflation medium, to the tissue traction device to control movement of the tissue traction device. The tissue traction system may include one or more flexible tubular elements, a distal end of which forms the tissue traction device.
