The objective of this clinical study is to evaluate the operative performance of the PEAK PlasmaBlade® 4.0 during bilateral breast reduction; to monitor and record post-operative pain, adverse events and skin scarring following surgery; and to compare these outcomes to the HARMONIC SYNERGY® BLADE.

Condition Intervention
Macromastia (Symptomatic)
Device: PEAK PlasmaBlade
Procedure: Scalpel and Traditional Electrosurgery

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind (Participant)
Primary Purpose: Treatment
Official Title: A Prospective, Randomized, Controlled Superiority Study to Evaluate Use of the PEAK PlasmaBlade® 4.0 in Bilateral Breast Reduction

Further study details as provided by Medtronic Surgical Technologies:

Primary Outcome Measures:
  • Difference in pain [ Time Frame: 24 hours and first 10 days post-op ]
    The primary endpoint will be the difference in pain between the Harmonic and PlasmaBlade operative sites. The primary efficacy variable will be pain at each treatment arm operative site, as measured by visual analog scale for 24 hours post-operatively and for 10 post-op days twice daily.

Secondary Outcome Measures:
  • Operative performance [ Time Frame: Intraoperatively on day 0 ]
    Dissection time (normalized), estimated blood loss, use of traditional device for bleeding control, volume of tissue resection.

  • Adverse events [ Time Frame: 1 month post-operatively ]
    Monitoring for adverse events following surgery, including hematoma, seroma, wound dehiscence, etc.

  • Cutaneous scarring [ Time Frame: Up to one year post-operatively ]
    Scar width, quality, pigmentation, elevation, nodularity, thickness, and cosmetic appearance will be blindly evaluated by subject and independent observers.

Primary Completion Date: October 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: PEAK PlasmaBlade Device: PEAK PlasmaBlade
Active Comparator: Standard of Care
The Standard of Care arm will consist of the scalpel for the skin incision and traditional electrosurgery for subcutaneous dissection.
Procedure: Scalpel and Traditional Electrosurgery
