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.
