Abstract: A protective sheath apparatus and method for protecting surgical conduits from contamination by liquids resulting from a surgical procedure. The protective sheath also provides a restraint system for securing the various surgical conduits on the surgical field. The protective sheath is configured as a tubular element fabricated from a liquid-resistant, fabric-like material. An annular shield is affixed to one end of the tubular element and serves as the entry for inserting the surgical conduits through the tubular element. A pair of guide members are mounted to the shield and serve as a basal element over which the tubular element is longitudinally folded and as a guide for assisting in the passage of the surgical conduits through the folded tubular element. Retainer strings releasably hold the tubular element in its telescopically folded configuration.
