TECHNICAL FIELD

The present application relates generally to the field of prepectoral or subcutaneous breast reconstruction.

BACKGROUND

The use of acellular dermal matrices (ADMs) or acellular tissue matrices (ATMs) has become more prevalent in immediate one stage (i.e., direct to implant) and staged breast reconstruction (i.e., tissue expander followed by implant). These ADMs and ATMs are derived from cadaveric dermis and are composed primarily of extracellular matrix (ECM) components. The ADMs and ATMs function to provide a scaffold upon which resident (i.e., host) cells migrate following implantation, facilitating matrix integration and incorporation.

SUMMARY

In an embodiment, a reconstruction support is provided for insertion above muscle for the facilitation of breast reconstruction. The reconstruction support includes an upper half, a lower half joined to the upper half, a plurality of alignment perforations disposed on at least one of the upper half and the lower half, and a plurality of fenestrations disposed on at least one of the upper half and the lower half. The plurality of fenestrations is configured to facilitate selective expansion of at least one of the upper half or the lower half.

In another embodiment, a reconstruction support is provided for insertion above muscle for facilitation of breast reconstruction. The reconstruction support includes an upper half, a lower half, and a plurality of fenestrations. The lower half is integrated with the upper half. The plurality of fenestrations is disposed on at least one of the upper half and the lower half. The plurality of fenestrations is configured to facilitate selective expansion of at least one of the upper half or the lower half. The plurality of fenestrations is arranged in a plurality of substantially parallel rows. The plurality of substantially parallel rows includes a first row containing a first subset of the plurality of fenestrations, a second row positioned adjacent the first row containing a second subset of the plurality of fenestrations, a third row positioned adjacent the second row such that the second row is positioned between the first row and the third row and containing a third subset of the plurality of fenestrations, and a plurality of substantially concentric arcs. The plurality of substantially concentric arcs includes a first arc containing a fourth subset of the plurality of fenestrations and a second arc positioned adjacent the first arc and containing a fifth subset of the plurality of fenestrations.

In another embodiment, a reconstruction support is provided for insertion above muscle for facilitation of breast reconstruction. The reconstruction support includes an upper half, a lower half, and a plurality of fenestrations. The lower half is integrated with the upper half. The plurality of fenestrations is disposed on at least one of the upper half and the lower half. The plurality of fenestrations is configured to facilitate selective expansion of at least one of the upper half or the lower half. The plurality of fenestrations is arranged in a first row containing a first subset of the plurality of fenestrations and a first arc containing a fourth subset of the plurality of fenestrations. The reconstruction support is bisected by a horizontal plane. The first arc is bisected by the horizontal plane. The horizontal plane separates the upper half from the lower half. The first row is contained within one of the upper half and the lower half.
