NCT00943150

Brief Summary

The objective of this clinical study is to evaluate healing of incisions made with the PEAK PlasmaBlade 4.0 compared to scalpel and traditional electrosurgery (Bovie); to monitor and record key post-operative metrics following abdominoplasty with the PEAK PlasmaBlade 4.0 versus current standard of care (SOC); and to evaluate performance metrics of the PEAK PlasmaBlade 4.0 during abdominoplasty.

Outcome Measures

Primary Outcomes (2)

  • Acute Thermal Injury Depth

    Histological samples were created by first incising the area to be resected with all 3 modalities (PEAK PlasmaBlade, electrocautery, and scalpel) at 6 and 3 weeks before the operation. Then, the incised tissue was resected during the abdominoplasty and was assessed by analyzing incisions created in the resected area for histological measures. Acute thermal injury depth was assessed by incising the resected area during the abdominoplasty operation.

    Immediately postoperative

  • Inflammatory Cell Count

    Histological samples were created by first incising the area to be resected with all 3 modalities (PEAK PlasmaBlade, electrocautery, and scalpel) at 6 and 3 weeks before the operation. Then, the incised tissue was resected during the abdominoplasty and was assessed by analyzing incisions created in the resected area for histological measures.

    0, 3, and 6 weeks
