## Abstract

A medical device, comprising a tube including at least one lumen, an absorbent located at a distal portion of the tube, the absorbent being configured to transition from a compressed state to an expanded state, and a structure fixed to the absorbent, 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.

## Claims

### Claim 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.

### Claim 2 (depends on 1)

The medical device of claim 1, wherein the absorbent comprises a foam, a sponge, a gel, or combinations thereof.

### Claim 3 (depends on 1)

The medical device of claim 1, wherein the structure includes one or more woven wires.

### Claim 4 (depends on 1)

The medical device of claim 1, wherein the structure is fixed to the absorbent via adhesion, sewing, or molding.

### Claim 5 (depends on 1)

The medical device of claim 1, wherein the absorbent assumes a substantially spherical configuration when in the expanded state.

### Claim 6 (depends on 1)

The medical device of claim 1, further comprising a wire coupled to a portion of the netting, wherein the wire is configured to shear the netting from the absorbent by an application of a force to the wire, thereby transitioning the absorbent from the compressed state to the expanded state.

### Claim 7 (depends on 1)

The medical device of claim 1, wherein the absorbent is exposed from within the structure.

### Claim 8

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;
a structure fixed to the absorbent and including a cavity, 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;
an actuation tube movable within the at least one lumen and relative to the absorbent, wherein the actuation tube is connectable with a vacuum source to supply a negative pressure to the absorbent via a distal opening of the actuation tube; and
a wire coupled to a netting surrounding the absorbent and the structure, wherein
the wire is configured to shear the netting to transition the absorbent from the compressed state to the expanded state,
wherein a distal end of the first tube extends distally past the absorbent, thereby exposing the distal end of the first tube, and
wherein the actuation tube is configured to supply the negative pressure to the absorbent when the distal end of the first tube and the distal opening of the actuation tube are within the cavity.

### Claim 9 (depends on 8)

The medical device of claim 8, wherein the actuation tube is configured to extend distally and/or retract proximally within the at least one lumen.

### Claim 10 (depends on 1)

The medical device of claim 1, wherein at least a portion of the structure is coated with at least one drug.

### Claim 11 (depends on 1)

The medical device of claim 1, further comprising an end effector, wherein the end effector is coupled to the distal portion of the first tube.

### Claim 13

A medical device, comprising:
a first tube including at least one lumen;
an absorbent at a distal portion of the first tube, wherein the absorbent is configured to transition between a compressed state and an expanded state;
an actuation device within the at least one lumen, wherein the actuation device is a second tube configured to move distally and proximally relative to the absorbent, and the actuation device is connectable with a vacuum source to supply a negative pressure to the absorbent;
a stent surrounding the absorbent, wherein the stent is fixed to an outer surface of the absorbent, and the stent exposes at least a portion of the absorbent; and
a containment configured to maintain the absorbent in the compressed state,
wherein the containment is a netting, a wrapping, or a suture, and
wherein the stent includes a first opening and a second opening, wherein the first tube is configured to extend outside of the stent and the absorbent and retract within the stent and the absorbent through the first opening and the second opening, such that the first tube and the second tube are the only tubes within the stent and the absorbent.

### Claim 14 (depends on 13)

The medical device of claim 13, wherein the stent comprises a bioabsorbable material.

### Claim 15 (depends on 14)

The medical device of claim 14, wherein the stent comprises one or more woven wires.

### Claim 16 (depends on 13)

The medical device of claim 13, wherein the absorbent further includes a cavity configured to contain a distal end of the first tube when the first tube is retracted into the cavity, and
wherein the actuation device is configured to supply the negative pressure directly to the absorbent via a distal opening of the actuation device when the distal end of the first tube is retracted within the cavity of the absorbent.

### Claim 17 (depends on 12)

The medical device of claim 12, wherein the cautery device is coupled to the exposed distal end of the first tube.

### Claim 18 (depends on 8)

The medical device of claim 8, wherein the wire extends through a lumen of the first tube.

### Claim 19 (depends on 13)

The medical device of claim 13, wherein the containment is a netting, and wherein the netting is coupled to a wire configured to shear the netting.

### Claim 20 (depends on 8)

The medical device of claim 8, further comprising a cautery device coupled to the distal portion of the first tube.
