1. A medical device comprising:
a longitudinal portion with a plurality of discrete tubes configured to be spaced around an exterior of an endoscope, wherein each tube includes a channel;
a distal portion with a plurality of arms, wherein each of the arms includes an arm lumen, wherein each arm lumen is connected to a respective channel of a respective tube, wherein the channels and arm lumens are aligned and configured to receive and deliver one or more end effectors out of the arm lumens, and wherein the distal portion is configured to be coupled to an outer surface of a distal end of the endoscope; and
one or more actuation mechanisms, wherein the one or more actuation mechanisms are movable to transition the plurality of arms from a closed configuration to an open configuration, wherein in the closed configuration, the arm lumens are not exposed from the distal portion, and wherein in the open configuration, the arm lumens are exposed from the distal portion, and wherein the arm lumens are distal of the endoscope in the closed configuration, wherein the arm lumens extend from interior portions of the arms and curve towards a longitudinal axis of the endoscope and are configured to deliver the one or more end effectors to a target treatment site.
