Abstract: An accessory device for use with a medical device includes a first cuff secured to a distal end of the medical device, a second cuff secured to the medical device proximal of the first cuff, an actuator, and at least one actuation wire extending from the first cuff, through the second cuff, to the actuator.

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: The present disclosure, in its various aspects, is directed to expandable guide devices, implementation methods, and related systems. In one example, an expandable guide device is configured to receive an instrument through an instrument lumen of the device. Each of a plurality of expandable members are disposed circumferentially about a body of the device that defines the instrument lumen, and each expandable member is configured to be independently transitionable between an expanded configuration and an unexpanded configuration.

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.
