## Abstract

According to one aspect, a medical device system may comprise a bag including a first opening; a pad coupled to the bag proximate to the first opening; and a tube including a distal portion. The distal portion may be coupled to the pad and includes at least one opening; and the tube may be configured to provide negative pressure therapy to a wound site.

## Claims

### Claim 1

A medical device system comprising:
a bag including a first opening;
a pad coupled to the bag proximate to the first opening; and
a tube including a distal portion, wherein the distal portion is coupled to the pad and includes at least one opening;
wherein the tube is configured to provide negative pressure therapy to a wound site.

### Claim 2 (depends on 1)

The medical device system of claim 1, further comprising a pump assembly fluidically coupled to the tube, wherein the pump assembly applies negative pressure to the tube.

### Claim 3 (depends on 1)

The medical device system of claim 1, wherein the pad is circular and includes a central lumen, and wherein the central lumen aligns with the first opening.

### Claim 4 (depends on 3)

The medical device system of claim 3, wherein the distal portion of the tube extends circumferentially around the central lumen.

### Claim 5 (depends on 4)

The medical device system of claim 4, wherein the at least one opening of the tube includes a plurality of openings, and wherein the plurality of openings face a direction towards the pad.

### Claim 6 (depends on 1)

The medical device system of claim 1, further comprising a filter assembly coupled to the tube and configured to filter material received from the wound site.

### Claim 7 (depends on 2)

The medical device system of claim 2, wherein the pump assembly includes a pump and a reservoir configured to receive material from a wound site.

### Claim 8 (depends on 1)

The medical device system of claim 1, wherein the pad includes a channel configured to receive the tube, wherein the channel extends circumferentially around a central lumen of the pad.

### Claim 9 (depends on 1)

The medical device system of claim 1, wherein the pad includes a perforated portion configured to be removable from the pad.

### Claim 10 (depends on 1)

The medical device system of claim 1, wherein the pad includes a first layer of porous material and a second layer of porous material, and wherein a portion of the tube is positioned between the first layer of porous material and the second layer of porous material.

### Claim 11 (depends on 1)

The medical device system of claim 1, wherein the pad includes an adhesive on a first side of the pad, and wherein the adhesive extends across a first portion of the first side of the pad and not across a second portion of the first side of the pad.

### Claim 12 (depends on 1)

The medical device system of claim 1, further comprising a wafer, wherein a first side of the wafer is configured to couple the bag to the wafer, and wherein a second side of the wafer is configured to couple the pad to the wafer.

### Claim 13 (depends on 12)

The medical device system of claim 12, wherein the wafer includes a convex portion, wherein the convex portion extends circumferentially around a central lumen of the wafer, and wherein the tube is positioned radially-outward, relative to a central longitudinal axis of the central lumen, relative to the convex portion.

### Claim 14 (depends on 2)

The medical device system of claim 2, wherein the bag includes a pocket and the pump assembly is positioned within the pocket.

### Claim 15 (depends on 1)

The medical device system of claim 1, wherein the pad is C-shaped.
