About this study

This is a prospective, multi-center, single arm, open-label, continued access clinical study. Subjects who meet the inclusion criteria and agree to participate in the study will be enrolled and implanted with the investigational AeroForm Tissue Expander. If the subject is having a bilateral procedure, the AeroForm expander will be implanted in each side. Subjects will be followed until the first post-operative visit after explant of the tissue expander(s) and exchange for permanent implant(s).

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Subject is female between the ages of 18-70
  • Subject requires tissue expansion as part of breast reconstruction
  • Subject is able to provide written informed consent
  • Subject is able and willing to comply with all of the study requirements
  • Subject has the physical, perceptual and cognitive capacity to understand and manage the at home dosing regimen

Exclusion criteria

  • Subject's tissue integrity is unsuitable for tissue expansion
  • Subject has residual gross malignancy at the intended expansion site
  • Subject has current or prior infection at the intended expansion site
  • Subject has a history of failed tissue expansion or breast reconstruction
  • Subject has any co-morbid condition determined by the Investigator to place the subject at an increased risk of complications (e.g., severe collagen vascular disease, poorly managed diabetes)
  • Subject is taking any concomitant medications determined by the Investigator to place the subject at an increased risk of complications (e.g., Prednisone, Coumadin).

Treatment and study plan

AeroForm Tissue Expander

Device

The AeroForm 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.

Primary outcomes

  1. Number of Breasts With Successful Tissue Expansion With Exchange to a Permanent Breast Implant Unless Exchange is Precluded by a Non-device Related Event

    Time frame: 6 months

    The primary endpoint is analyzed per breast. Breasts in which the expander is removed and/or replaced due to a device related adverse event or a device malfunction are counted as failures.

Secondary outcomes

  1. Number of Breast With Successful Tissue Expansion With Exchange to Permanent Implant Including All Breasts in the Per Protocol Cohort.

    Time frame: 6 months

    Secondary analysis is repeated including all breasts in the PP cohort (including non-device related failures). The Treatment Success Rate by breast, based on the Per Protocol cohort, including all cause failures, is 95.2% (80/84). One subject (2 breasts) are not included in the analyses due to not completing the second stage surgery and withdrawal of consent.
