Medical systems, devices, and related methods

A medical system, comprising:

• an endoscope, including a distal end;
• a medical device, wherein the medical device includes:
• a handle, wherein the handle includes a primary actuator and one or more secondary actuators, wherein the one or more secondary actuators are movably positioned within one or more channels in the primary actuator;
• an end cap coupled to the distal end of the endoscope, wherein the end cap includes a stationary portion and a movable portion, and wherein the movable portion includes a proximal ring and a distal ring;
• one or more patches, wherein the one or more patches are coupled to the movable portion of the end cap between the proximal ring and the distal ring;
• one or more control elements coupling the primary actuator to the movable portion of the end cap;
• and
• one or more actuation elements, wherein the one or more actuation elements extend from the one or more secondary actuators to a position between a portion of the one or more patches and the movable portion of the end cap,
• wherein movement of the primary actuator moves the movable portion of the end cap relative to the stationary portion of the end cap and relative to the endoscope, and
• wherein movement of the one or more secondary actuators at least partially deploys the one or more patches from the movable portion of the end cap.

A medical device, comprising:

• a handle, wherein the handle includes one or more actuators;
• an end cap configured to be coupled to a distal end of another medical device, wherein the end cap includes:
• a proximal ring including a proximal groove,
• a distal ring including a distal groove, and
• a body portion between the proximal ring and the distal ring;
• one or more patches, wherein the one or more patches are coupled to the end cap such that a portion of each of the one or more patches is positioned within the proximal groove, and such that another portion of each of the one or more patches is positioned within the distal groove;
• and
• one or more actuation elements, wherein the one or more actuation elements extend from the one or more actuators to a position between a portion of the one or more patches and the body portion of the end cap,
• wherein a distal portion of each of the one or more actuation elements is positioned within the distal groove, and
• wherein movement of the one or more actuators at least partially deploys the one or more patches from the end cap.
