Abstract

A system for providing negative-pressure therapy to breast tissue is disclosed. In some embodiments, the system may include a dressing assembly shaped for placement on a breast, an absorbent pouch, and a negative-pressure source. The system may further include an additional dressing assembly for placement on a second breast. Various shapes and configurations of the breast dressing assemblies may be included in the system.

Claims (19)

1. A system for providing negative-pressure treatment, the system comprising:

a first dressing assembly shaped for placement on a breast and comprising:

a crown comprising a substantially circular section having a diameter and adapted to cover an areola, and

an elongate arm having a medial portion forming a first end of the elongate arm and a lateral portion forming a second end of the elongate arm, the elongate arm adapted to cover a wound site along an inframammary fold,

wherein the first dressing assembly further comprises:

a dressing tissue interface formed from a silicone adhesive, the dressing tissue interface comprising a first surface adapted to adhere to the breast and comprising perforations,

a dressing manifold having a first side and a second side, wherein the first side of the dressing manifold is disposed against a second surface of the dressing tissue interface, and

a dressing cover disposed on the second side of the dressing manifold and having an adhesive border for sealing the dressing manifold and the dressing tissue interface to the breast;

a bridge extending from the second end formed by the lateral portion of the elongate arm, the bridge being perpendicular to the elongate arm;

wherein each of the crown, the elongate arm, and the bridge comprises a portion of the dressing tissue interface, the dressing manifold, and the dressing cover;

a second dressing assembly;

an absorbent pouch comprising a first port configured to be in fluid connection with the first dressing assembly, a second port adapted for receiving negative pressure, and a third port configured to fluidly connect the second dressing assembly to an interior of the absorbent pouch; and

a negative-pressure port positioned on the first dressing assembly and configured for fluid communication with a negative-pressure source.

2. The system of claim 1 , wherein the first dressing assembly further comprises a connector positioned proximate to a lateral terminus of the bridge.

3. The system of claim 1 , wherein the perforations consist of a first plurality of holes in the crown and a second plurality of holes in the elongate arm.

4. The system of claim 2 , wherein the dressing manifold comprises a plurality of fibers oriented towards the lateral terminus of the bridge.

5. The system of claim 4 , wherein the plurality of fibers are oriented towards the connector.

6. The system of claim 1 , wherein the silicone adhesive is a low-tack silicone adhesive.

7. The system of claim 1 , wherein the first dressing assembly and the second dressing assembly comprise different geometries.
