The present invention, in the preferred embodiment, is a surgery recovery brassiere which resolves many of the problems faced by women who have undergone breast surgery and particularly, mastectomy. The present invention comprises front panels, prosthesis panels, rear panels, torso band, straps, drain tube apertures and fluid collection storage pouch.More specifically, two front panels each comprise a cup portion and a conforming portion. The prosthesis panels are attached to the rear facing of the cup portion of the front panel to form enclosed pockets to hold one or two prosthesis. Each of the two rear panels are joined at one end to the front panels and extend to meet the opposing rear panel at a back closure. The free end of each of the front panels meet to form a front closure. Straps extend from the top of the front panel to the top of the adjacent rear panel. The torso band extends around the lower edge of the surgery recovery brassiere to form an almost continuous strip of material along the lower edge of the front and rear panels.The surgery recovery brassiere further accommodates post-operative surgical drainage systems composed of one or more drain tubes and associated fluid collection bulbs. The position of drainage tube apertures, generally located proximate to the joint between the front and rear panels, allow drainage tubes to protrude from the chest wall, through the apertures and into the collection storage pouch. Tab closures allow the wearer to secure the drainage tubes within the aperture to further reduce movement of the tubes and disturbance of the drainage system. The storage pouch provides pockets with elastic top entry so that collection bulbs are within easy, convenient reach for emptying lymphatic fluids and other waste materials. The upper edge of the storage pouch releasably attaches to the torso band with a hook-and-loop fastener system.

Absorbable implants for breast surgery that conform to the breast parenchyma and surrounding chest wall have been developed. These implants support newly lifted breast parenchyma, and/or a breast implant. The implants have mechanical properties sufficient to support a reconstructed breast, and allow the in-growth of tissue into the implant as it degrades. The implants have a strength retention profile allowing the support of the breast to be transitioned from the implant to regenerated host tissue, without significant loss of support. Three-dimensional implants for use in minimally invasive mastopexy/breast reconstruction procedures are also described, that confer shape to a patient's breast. These implants are self-reinforced, can be temporarily deformed, implanted in a suitably dissected tissue plane, and resume their preformed three-dimensional shape. The implants are preferably made from poly-4-hydroxybutyrate (P4HB) and copolymers thereof. The implants have suture pullout strengths that can resist the mechanical loads exerted on the reconstructed breast.

A post operative breast surgery drain support garment including a form fitting support structure and one or more pouches attached to the front of the support structure and unobstructed from access. Each pouch is adapted in size and shape so as to form fittingly receive and maintain therein a single drainage receptacle. A drainage tube passes through drainage tube openings defined in the garment. Retaining devices are releasably mounted to the support structure and extend across at least a portion of the drainage tube openings to retain the drainage tube against the body thereby minimizing uncomfortable tugging. Retaining devices preferably include two main releasable retaining devices disposed substantially horizontal and substantially parallel to one another. Additional restraint may be provided by a supplemental retaining device disposed substantially perpendicular to the first and second main releasable retaining devices. The retaining devices substantially inhibit movement of the drainage tube thereby minimizing uncomfortable tugging of the drainage tube at the point of exit from the body.

Full contour absorbable implants for breast surgery redistribute breast volume between the breast's upper and lower poles in exact and desirable ratios. The implants preferably redistribute breast volume so that the upper pole breast volume is 20-40% of the total volume, and the lower pole breast volume is 60-80% of the total volume. The implants are also designed to provide specific curvatures to the poles of the breast, and to angulate the nipple areolar complex slightly skyward so that the patient's nipple is positioned at an angle above the nipple meridian reference line. The implants are designed to be transitory, with sufficient strength retention to allow transition from support of the breast by the implant to support by regenerated host tissue growing in and around the implants, without any significant loss of support during or subsequent to remodeling. The implants may optionally be used with permanent breast implants.
