Abstract: A device may include an elongated housing formed of an optically transparent material, the housing extending from a proximal end to a distal end and including a lateral wall extending from the proximal end to a distal tip of the housing, the housing defining a lumen extending into the housing from a proximal opening in the proximal end of the housing. The device also may include a first port extending through the lateral wall of the housing to open the lumen of the housing to an exterior of the housing, the first port being sized and shaped to receive therein a target portion of tissue to be inspected and/or treated.

Abstract: Medical devices for applying a cinch to a suture and methods for making and using such devices are disclosed. An example medical device may include an elongated shaft including a proximal region and a distal region. The distal region may define a lumen having a lumen dimeter, and a distally facing end surface. The medical device may also include an outer cinch member defining a bore and having an outer surface defining a shoulder. An elongated inner shaft may extend through and be longitudinally movable within the lumen and the bore and including a distal end section. An inner cinch member may be engaged with the distal end section of the elongated inner shaft.

Abstract: Exemplary embodiments of the present disclosure relate to devices, systems, and methods for tissue resection in a body lumen of a patient, and may include an elongate body having a cavity at a distal end and a tissue retractor extendable distally from the distal end of the elongate body. The tissue retractor may include an expansion mechanism. The expansion mechanism may include a plurality of arms each having a first end coupled around a distal cap and expandable radially outward from the distal cap such that an anchoring mechanism on a second end of the arms is engageable with selected tissue for resection of the body lumen. The tissue resection device may further include a tissue resecting device.

Abstract: An endoscopic handle attachment is adapted to be secured to an endoscope having a working channel and used in combination with a suture device adapted to extend through the working channel. The attachment includes a backbone adapted to conform to an outer surface of the endoscope and that includes one or more attachment features adapted to enable releasable securement to the endoscope. A primary arm extends radially outwardly from the backbone and includes one or attachment points, at least one of the one or more attachment points adapted to releasably secure a proximal handle of the suture device such that a translation handle may be moved relative to the proximal handle without an operator needing to separately hold the proximal handle.

Abstract: A tissue grasping device for use with an endoscope may include a sheath, a control wire slidably disposed within the sheath, and a helical coil disposed over and attached to the control wire. The helical coil may include a proximal region in which adjacent windings are in contact, and a distal region in which adjacent windings are spaced apart. The helical coil may have a sharpened distal tip.

Abstract: A device includes a handle having a trigger in combination with a distal portion, the distal portion including a rigid elongated hollow member which receives tissue therein and a plunger fitted with and configured to slide longitudinally within the hollow member to induce suction at a distal end of the hollow member as the plunger is moved proximally within the hollow member. The trigger is hingedly coupled to the plunger so that pulling the trigger slides the plunger proximally with respect to the hollow member to generate suction to draw the tissue into the distal end of the hollow member. The device further includes a tissue treatment mechanism for encircling the tissue received at the distal end of the hollow member.
