Terms & Conditions of Use

A new carbon dioxide-filled tissue expander offers a needle-free, patient-controlled alternative for breast reconstruction. This innovative device significantly reduces expansion and overall reconstruction times compared to traditional saline methods.

Area of Science:

Plastic Surgery
Biomedical Engineering
Medical Devices

Background:

Two-stage saline tissue expander-to-implant procedures are the standard for breast reconstruction in the US.
For decades, saline tissue expanders have been the established method for prosthetic reconstruction.
Percutaneous saline injections are typically required for traditional tissue expander-based breast reconstruction.

Purpose of the Study:

To evaluate the novel AeroForm Tissue Expander System, a carbon dioxide-filled device for breast reconstruction.
To compare the efficacy and patient experience of the CO2-filled expander against traditional saline expanders.
To assess the impact of a patient-controlled, needle-free tissue expander on reconstruction timelines.

Main Methods:

A multicenter, randomized, prospective clinical trial was conducted.

The study compared the AeroForm Tissue Expander System with conventional saline tissue expanders.

Patient-controlled, wireless remote device operation was utilized for CO2 expansion.

Main Results:

The AeroForm system demonstrated statistically significant shorter times to full expansion.
Overall reconstructive times were significantly reduced with the CO2-filled expander.
The device offers patient-controlled, needle-free expansion, eliminating the need for saline injections.

Conclusions:

The carbon dioxide-filled AeroForm Tissue Expander System presents a novel advancement in breast reconstruction.
This CO2-filled expander offers advantages including patient convenience, needle-free operation, and reduced expansion duration.
The system represents a significant departure from traditional saline-based tissue expanders, improving patient outcomes and procedural efficiency.
