Patient Activated Controlled Expansion (PACE) Trial
Patient Activated Controlled Expansion (PACE) for Breast Reconstruction Utilizing Controlled CO2 Inflation
The purpose of this study is to determine whether a patient controlled tissue expander can improve the results and patient experience in breast reconstruction. The study hypothesis is that patient controlled expansion will lead to rapid and more comfortable outcomes than historical precedents.

Title: Patient Activated Controlled Expansion (PACE) for Breast Reconstruction Utilizing Controlled CO2 Inflation

Design: Prospective, open-label, single-arm, feasibility trial Purpose: To evaluate the AirXpanders tissue expander in patients undergoing breast reconstruction surgery following mastectomy.

Enrollment: This feasibility trial will enroll up to 10 patients. Following enrollment of the first 5 patients, the sponsor will determine if additional subjects will be recruited to further evaluate treatment outcome.

Clinical Sites: Up to 3 sites and 3 surgeons will participate in this study. The surgeon(s) should have the necessary qualifications and sufficient experience (minimum of 12 breast tissue expanders placed per year) to participate in the trial.

Duration of Patient Participation: Eligible patients will be enrolled over approximately 2 months.

Patients will be instructed on the tissue expansion protocol pre-operatively and undergo post-operative clinical follow-up on a weekly basis or more frequently if deemed necessary by the treating surgeon.

Each patient will be followed through removal of the tissue expander.

Study Population:

The study population will consist of up to 10 patients. Eligible patients are females between the ages of 18 and 65 years who are planning to undergo breast reconstruction surgery following mastectomy. Eligible patients must be able to provide informed consent and understand protocol components.
