• Subject was a current or former tobacco/nicotine user, within 90 days prior to Index Surgery (i.e., TE placement).
• Subject is currently taking medication (e.g., systemic steroid), which in the investigator's opinion, may increase the risk of local complications of breast reconstruction.

• Subject is pregnant or lactating at the time of the index procedure (i.e., TE placement) or is planning to become pregnant prior to the Exchange procedure. Intraoperative Index Procedure Exclusion
• Based on investigator's opinion, subject has unsuitable tissue integrity for immediate 2-stage breast reconstruction or is no longer a candidate to receive the TRBR Device (will be recorded as a screen failure).
• Subject receives an Acellular Dermal Matrix (ADM) or mesh that is not the TRBR Device in the target breast(s)
