Device: AeroForm Tissue Expansion
Procedure: Saline Tissue Expansion
Phase 2

Study Type: Interventional

Primary Outcome Measures:
  • Successful tissue expansion and exchange to a permanent breast implant unless precluded by a non-device related event [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    The primary endpoint will be assessed when the subject has completed tissue expansion and had an exchange to permanent breast implants. Subjects not completing permanent breast implant procedure will be considered failures if the procedure could not be completed due to a device related event.

Secondary Outcome Measures:
  • The safety of the device will be evaluated by the data collected on device related adverse events, serious device related adverse events, all adverse and serious adverse events (regardless of their relationship to the device), and device malfunctions [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
    All adverse events will be collected and reported during the time that the expander is implanted. All events will be reported and categorized based on their relationship to the device or procedure. All device malfunctions will be reported.

Estimated Enrollment: 138
Study Start Date: October 2011
Estimated Study Completion Date: January 2015
Estimated Primary Completion Date: December 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: AeroForm Tissue Expansion
AeroForm Tissue Expansion inflation with carbon dioxide by remote control
Device: AeroForm Tissue Expansion
The AeroForm Patient Controlled Tissue Expander is a breast tissue expander implanted following mastectomy and activated by remote control to release small doses of carbon dioxide from an internal reservoir to fill and inflate the expander.
Other Names:
  • AirXpander Tissue Expander System
  • Patient Activated Controlled Expansion (PACE)
  • AeroForm Patient Activated Tissue Expander
  • AeroForm Tissue Expander System
  • AeroForm Tissue Expander
Active Comparator: Saline Tissue Expansion
Saline Tissue Expansion inflated by needle injections of saline
Procedure: Saline Tissue Expansion
A saline tissue expander is a breast tissue expander which is implanted following mastectomy and inflated over time using needle injections to fill and inflate the expander with saline.
Other Names:
  • saline breast tissue expander
  • saline expander
  • breast tissue expander
  • tissue expander

Detailed Description:

This is a pivotal, prospective, multi-center randomized, controlled, open-label clinical study designed to compare the performance and safety of the AirXpander Tissue Expander System to currently cleared saline tissue expanders. Subject who meet the inclusion and agree to participate in the study will be enrolled and randomized to either the investigational arm (AirXpander Tissue Expander) or the control arm (standard saline tissue expander) using a 2:1 (AirXpander to saline) permuted block randomization stratified by investigational center and procedure (unilateral or bilateral). If the subject is having a bilateral procedure, the same type of expander will be implanted in each side. Subjects in both arms will be followed in the same manner until the explantation of the tissue expander(s) and exchange for permanent implant(s).


Ages Eligible for Study:   18 Years to 70 Years
Genders Eligible for Study:   Female
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  1. Subject is a woman between the ages of 18-70.
  2. Subject needs to have tissue expansion as part of her breast reconstruction.
  3. Subject is able to provide written informed consent.
  4. Subject is able and willing to comply with all of the study requirements.
  5. Subject is able to understand and manage at home dosing regimen.

Exclusion Criteria:

  1. Subjects skin is not suitable for tissue expansion.
  2. Subject has remaining tumor cells following her mastectomy.
  3. Subject has a current or prior infection at the intended expansion site.
  4. Subjects skin has been damaged by previous radiation treatments and the use of non radiated tissue from another part of her body will not be used.

4a. Subject had planned radiation therapy at the intended expansion site while the expander is implanted.

5. Subject has a history of failed tissue expansion or breast implantation at the intended expansion site.

6. Subject has any existing medical condition that the doctor thinks puts the subject at an increased risk of complications (e.g., severe collagen vascular disease, poorly managed diabetes).

7. Subject is taking any medications that the doctor thinks puts the subject at an increased risk of complications (e.g., prednisone, Coumadin).

8. Subject is currently participating in a concurrent investigational drug or device study.

9. Subject is a current tobacco smoker. 10. Subject is overweight (BMI > 33). 11. Subject is unwilling to comply with the air travel or altitude restriction of not > 3300 feet (1000 meters) from baseline during the time the AeroForm tissue expander is implanted.

12. Subject has a currently implanted electronic device such as a pacemaker, defibrillator, neurostimulator device, or drug infusion device.

13. Subject is pregnant or planning on becoming pregnant during the study period.

14. Subject has a history of psychological condition, drug or alcohol misuse which may interfere with their ability to use the device safely.
