HARMONIC ACE®+ Shears with Adaptive Tissue Technology
Enhanced precision vs HARMONIC ACE® Shears
- 23% less thermal spread1 reduces tissue damage to surrounding vital structures
- 21% shorter transection times2 with the same reliable hemostasis you expect from HARMONIC ACE®
- Refined blade design enables precision in dissection, sealing, transection, grasping, and otomy creation Advanced energy delivery through Adaptive Tissue Technology
- New technology responds intelligently to tissue conditions for greater precision
Regulates energy delivery when needed for improved temperature management
A tone change signals when Adaptive Tissue Technology is regulating energy delivery,thereby improving efficiency with enhanced feedback
- The surgeon retains ultimate control over the device
Adaptive Tissue Technology provides the benefits of greater precision without compromisingthe surgeon’s control of device function
HARMONIC ACE®+ Shears:
The precision of advanced energy delivery

1 23% less thermal spread exhibited in porcine histology vs HARMONIC ACE® Shears without Adaptive Tissue Technology (1.7mm vs 2.2mm; P<0.001).
2 21% shorter transection times measured in porcine labs vs HARMONIC ACE® Shears without Adaptive Tissue Technology (4.5s vs 5.7s;P<0.001).
3 In a benchtop study on Power Level 5, HAR36 and HAR23 exhibited 30.1% and 34.2% lower mean (P=0.000) and median (P=0.000)blade heat, respectively, than HARMONIC ACE® Shears without Adaptive Tissue Technology.
