Abstract

A surgical tissue bag for percutaneously debulking large volumes of tissue contained within the bag. The tissue bag comprises two layers of material, an inner layer of a puncture-resistant material and an outer layer of moisture-proof material for containing cells and fluid therein. The bag material is foldable and flexible for insertion through an access sheath into the surgical site and for forming a gas-tight seal when extended through the access sheath or puncture site. A drawstring is attached to the open end of the bag to close the bag when the tissue is contained therein and pulled through the puncture site in the outer surface of the skin. After the closed open end of the bag is pulled through the puncture site, the closed end is fanned out against the outer layer of the skin, and a morcellator is inserted into the bag for debulking the large volume of tissue. The open end of the bag is continually fanned out to maintain a compact and tight containment of the tissue and fluid remaining in the bag. The morcellation process is continued until the entire volume of tissue is removed at which time the remaining portion of the bag is completely removed from the surgical site area.
