简要总结
This phase 1 trial studies how well Blossom Smart Expander Technology works in breast reconstruction in participants with breast cancer undergoing mastectomy. Blossom Smart Expander Technology allows for slow and continuous injection of small amounts of saline, from an external pouch and based on precise pressure and volume measurements, into breast expander implants. It may help in achieving the same reconstructive goals as conventional tissue expansion in a shorter period of time and while avoiding frequent injections through the skin, which cause patient discomfort and require many clinic visits.
详细描述
PRIMARY OBJECTIVES:
I. To assess the clinical effectiveness of the application of Blossom Smart Expander Technology in 2-staged tissue expander/implant-based breast reconstruction.
SECONDARY OBJECTIVES:
I. Patient satisfaction. II. Patient self-reported pain. III. Incidence of complications.

结局指标
主要结局
Time to Full Expansion Defined as Number of Days Until Desired Breast Tissue Expansion Volume is Achieved
时间窗: Assessed weekly for up to 12 weeks
Measured by calculating the number of days from expander placement to achievement of desired expansion volume. Data were collected on a weekly basis until completion of breast expansion along with stabilization of surgical scars and percutaneous drain removal.
次要结局
- Number of Participants With Device Malfunction Associated With Tissue Expansion Process(Assessed weekly for up to 12 weeks)
- Pain Score(Assessed weekly for up to 12 weeks)
- BREAST-Q Reconstruction Module Version 2.0 Patient Satisfaction Score(Assessed weekly for up to 12 weeks)
- Number of Participants With Major Complications Associated With Tissue Expansion Process(Assessed weekly for up to 12 weeks)
