1. An electrosurgical generator, comprising:
a power supply configured for generating non-pulsing radiofrequency (RF) power having an output voltage and an output current; and
control circuitry configured to control delivery of the non-pulsing RF power to tissue being sealed by a tissue sealing device electrically connected to the generator, the non-pulsing RF power being delivered for a limited period of time,
wherein the limited period of time is no greater than 5 seconds and begins upon delivery of the non-pulsing RF power to the tissue, and
wherein the control circuitry is configured to hold the output current under 2 Amperes root mean square (RMS), and to hold the output voltage under 100 Volts RMS, respectively, throughout the limited period of time.
