    Abstract: A medical device including an application device with a first fluid path and a container movably attached to the application device. The container and the application device have a second fluid path therethrough, the container includes an inner chamber that is intermediate proximal and distal portions of the second fluid path, the inner chamber is fluidly isolated from the proximal portion of the second fluid path at a first position of the container, and the inner chamber is fluidly coupled to the proximal and distal portions of the second fluid path at a second position of the container. The first fluid path bypasses the container and the passage of fluid through the first fluid path is separately controllable from the passage of fluid through the second fluid path.

    Abstract: A handle for a medical device includes a proximal segment defining a proximal lumen extending therethrough and sized and shaped to receive an endoscopic medical device therein. A medial segment is received within a distal portion of the proximal segment and has an outer diameter smaller than an inner diameter thereof. A medial lumen extends through the proximal segment and is open to the proximal lumen. A distal segment is received within a distal portion of the medial segment and defines a distal lumen extending therethrough open to the medial lumen. The distal segment has an outer diameter smaller than an inner diameter of the medial segment. The medial segment includes a first movement limiting mechanism limiting movement of an endoscopic medical device inserted therethrough along an axis of the distal lumen and a second movement limiting mechanism limiting advancement of an endoscope attached to the distal body portion.

    Abstract: A system for treating tissue includes a capsule including a channel extending therethrough; first and second clip arms each extending from a proximal end to a distal end, the proximal ends being received within the channel of a capsule to be moved between an open tissue receiving configuration; and a closed tissue clipping configuration. The first clip arm includes a first tissue retention feature at a distal portion thereof configured to pierce through a target tissue when in the tissue clipping configuration and subsequently release the target tissue when the clip arms are moved to an at least partially open configuration. The second clip arm includes a second tissue retention feature at a distal portion thereof configured to pierce and retain the target tissue thereon when in both the closed tissue clipping configuration and the open tissue receiving configuration.
