1. A medical device, comprising:
a first tube including at least one lumen;
an absorbent located at a distal portion of the first tube, the absorbent being configured to transition from a compressed state to an expanded state, and wherein the first tube is movable relative to the absorbent;
an actuation tube movable within the at least one lumen and relative to the absorbent, wherein a proximal opening of the actuation tube is connectable with a vacuum source, and a distal opening of the actuation tube is configured to supply a negative pressure;
a structure fixed to the absorbent and including a cavity, wherein the cavity includes a distal opening and a proximal opening, wherein the structure is configured to flex into a compressed state and an expanded state simultaneously with the compressed state and the expanded state of the absorbent, and the structure exposes at least a portion of the absorbent; and
a netting configured to maintain the absorbent in the compressed state,
wherein the first tube extends through the distal opening and the proximal opening, thereby exposing a distal end of the first tube, and
wherein only the actuation tube is configured to supply a negative pressure to the cavity and the absorbent when the distal end of the first tube and the distal opening of the actuation tube are within the cavity.
