Abstract
A pulsed insulation system for administering an insufflation procedure includes a controller programmed to have a multi-mode operation. The controller switches the insufflation system to adjust an insufflation pressure to a nominal value in a first mode of operation of the controller. Upon encountering an obstruction by a Veress needle, the controller switches the insufflation system in a second mode, so as to adjust the insufflation pressure to a maximum target value and to have an interruption phase of pulse controllably increased. The interruption phase of pulse in the second mode is extended so as to enable a pressurized fluid accumulated at an upstream end of the Veress needle to dissipate therethrough before a measurement of the intracavity pressure is made.
