Abstract
A method using a sheathed surgical apparatus includes equalizing a pressure differential between a surgical insufflation gas pressure and an initial pressure lower than the insufflation gas pressure. The insufflation gas pressure is external to a portion of a surgical apparatus upon which a sheath is disposed, and the initial pressure is within the surgical apparatus. The equalizing of the pressure differential occurs via permeation of insufflation gas through the sheath.
