Abstract
Tissue sticking is substantially reduced or eliminated altogether by smoothing a working surface of a ceramic material or material with a ceramic-like surface microstructure of a tissue fusion instrument to an Ra in the range of less than 0.15 to 0.40 microns. The ceramic material may be aluminum nitride. Reducing or eliminating tissue sticking is particularly advantageous when fusing tissue.
